Public Service Announcement:
My Yucatecan wife explains that the local Yucatan news programs announced last night that: … For typical people, ONLY one person per car will be allowed to travel on Yucatan’s roads due to the COVID-19 problems …
and … All people in cars must wear face masks …

The news described exemptions for Uber drivers + 1 passenger … and for “essential personnel” … and for a driver taking someone to the hospital, doctor, or medical treatment.
** CAVEATS:
Uber driver +plus passenger = allowed
Taxi driver +plus passenger = allowed
Professional DRIVER with Chauffer’s License +plus passenger = allowed.
ALL OF THE ABOVE… +plus patient-passenger +Plus one companion … = allowed…
and … Ordinary driver … +plus patient-passenger … headed to some medical activity = allowed.
Then note… ALL must have on masks, when in the car … and ALL passengers must ride in the BACK-seat…
= = = =
Plus …
~ The government will be adding more police retenes (check-points) throughout the state … to check on compliance with the new sanctions.
All of the various new limitations (including the # of people in the car) STARTS FRIDAY (tomorrow) April 24, 2020 …

Per an April 17’th CFE & Federal Govt. of Mexico announcement:
“Se estima necesario que durante el período que se mantenga vigente la declaratoria de emergencia sanitaria por causa de fuerza mayor genera por el virus SARS-CoV2 (COVID-19), no se considere el consumo de energía eléctrica realizado por los usuarios del servicio doméstico […] así como permitir la permanencia de dichos usuarios en una tarifa de bajo consumo (1, 1A, 1B, 1C, 1D, 1E y 1F)”, establece el Acuerdo.”
” During this period of the declared National health emergency … because of the force majeure conditions, caused by the SARS-CoV2 virus (COVID-19) … Domestic home-owner electricity high consumption (DAC) usages will not be “charged” for their excessively high (DAC) consumptions. […] There will also be a “stay” (stoppage) – holding-maintenance-stabilization of high-energy user’s rates, keeping them in the low consumption rate categories (1, 1A, 1B, 1C, 1D , 1E and 1F)”, per the formal Agreement between CFE and the Gobierno de Mexico.”
“Con ello, los usuarios domésticos no pasarán a la tarifa de Servicio Doméstico de Alto Consumo (DAC) aunque rebasen el límite de consumo mínimo, es decir, que durante el periodo indicado, se les se les continuarán aplicando las tarifas 1, 1A, 1B, 1C, 1D, 1E y 1F, según corresponda.”
” This will prevent domestic users from going to the Domestic High Consumption Service (DAC) rate even if they exceed the minimum consumption limit, i.e. that during the period indicated, they will continue to be subject to rates 1, 1A, 1B, 1C, 1D, 1E and 1F, as applicable. “
“El acuerdo especificó que durante el periodo “no se podrán realizar reclasificaciones a la tarifa DAC a los usuarios de servicio doméstico de energía eléctrica”.
La CFE no cobrará más a usuarios que excedan su consumo de luz durante el aislamiento por COVID-19
“Through the agreement published in the evening version of the Official Gazette of the Federation (DOF), the Ministry of Finance and Public Credit (SHCP) determined that the measure will be effective between March 30, 2020 and up to seven calendar days after end the coronavirus emergency. “
= = = = = =
In simple language: Mary Maas explains (from FB):
“The notice is for the entire country (published in the official record), and is in effect from March 30 until six days after the emergency state is lifted. It says that CFE will not reclassify users who are in the domestic use tarifs 1A, 1B, 1C, 1D, and 1E ( which inclues Yucatan) from their domestic tariff to the domestic high consumption (DAC) tarif based on their usage during the emergency.”
Yet one more time … Mary Maas’s good addition … ~ ROCKS THE HOUSE ~

SATURDAY … in the park …
MAY 16 … 2020
Mark your calendars for a really fun event … to enjoy … as millions of people will be out looking into sky.. trying to see … ~this~ … faux News … imagined image.

BASED ON A BBC REPORT:
Fun hoaxers are claiming that on May 16, 2020 … Venus, Jupiter and a crescent Moon will ~ magically~ align and look like a smiling face looking down on us, it’s supposed to be a “quite a rare astronomical phenomenon” … and that it’s even hoak-ily called an occultation .
Can you say … “Fake News” ?
Why? …. Venus, Jupiter and the Moon will be in entirely different parts of the night sky on May 16, 2020.
= = = =
The worst lies are embroidered with lots of details … to suck people in.
It did not happen in 2008 … nor is it an occultation. (Occultations are defined as when one celestial object is hidden by another.)
REAL Occultations are a fun kind of celestial event … like when the moon is positioned between Earth and Venus – with Jupiter lurking in the background …
If it does happen at some point…
you might see one eye being … more twinkly … than the other.**
= = = =
Real Science…
** ~ Why could ~ “one eye be more twinkly than the other ~ ???
It’s due to regular “wavy” … rhythmic … partial-thermal lensing effects in our sky’s atmosphere, ( not due to the inherently-random “turbulence” that Lucy’s & Physicists incorrectly insist on ) …
Instead …. Think wavy rhythmic atmospheric air molecules, dancing, waving … between you & far-off dim Jupiter.
Yes … Physicists & other theoretical Know-it All’s … love parrot the old saw:
“ Only stars twinkle … ”
= = = =

Just like Lucy … older brothers… and older sisters … & physicists …
abusing their perpetually-younger brothers … like Linus …
= = = =
All the Lucy’s of the world … love to ~proudly ~ announce:
“Planets do not twinkle … ”
and then, they opine …
” … THAT’s how you can tell the difference between a planet and a star … ”
= = = =
But just like bossy-Lucy … insisting that everybody must believe what she imagines …
Instead …
In the real world … (versus artificial Physics-land ) …
People who actually look at the sky,
…. Know that some planets twinkle …
despite what years of Know-It-Alls have told us about “Stars twinkle … Planets don’t ”
= = = =
Why?
Why look for Jupiter “winking” at us … on May 16’th ??
When Jupiter & Saturn lie lower in our skies … nearer the horizon … rhythmic partial-thermal lensing (NOT random-turbulence) … rhythmic partial-lensing from rising warm air in our atmosphere … briefly deflects (re-directs) the dim light rays from Jupiter & Saturn off to other angles … for the person next to you see …

Rhythmic partial thermal lensing (due to rising heated air) moving the light beams
… is exactly the same as watching the “heat waves” ripple in the air … above a hot asphalt road … that bends & distorts … and ripples what we see ….
So yes, Charlie Brown …
It is sometimes best to ignore the loud-bossy Lucy’s of the world …
because what think you see … might actually be real …
regardless of what Lucy is telling you.
… Because rhythmic partial-thermal-lensing … by hot rising air …
… doesn’t even need a hot-asphalt road … to create a little wonder & mystery …

and yes … Linus …
That “twinkling” effect from warm air rhythmically gyrating the light we see is not the random, swirling “turbulence” that Physicists, Engineers & other Lucy’s insist on …
Instead, there are many kinds of various real wold events…. that real scientists enjoy … including rhythmic partial-thermal lensing …. and twinkly PLANETS !!

April 18, 2020
I received a curious email late last night … from a person fussing that $50 DHL express shipping from Yucatan to the USA just seemed “too high” … unreasonable.
= = = = = = =
Dear Friend …
Rather than worrying about $50 shipping seeming “too high” for 7 masks for me & my husband … Can you consider just one … of 7 paradigm shifts:
1. Consider the shipping to be both a useful step (like in a set of steps) … and it could be a bolt cutter that cuts~breaks the chain of COVID 19 infections … going beyond just protecting you.
Instead of just buying a few for your self… consider using that same $50 shipping cost to ship 50 … and ~give~ 40 to your local nursing home personnel … who likely do NOT have any decent masks … and certainly none of this medical grade mask’s high efficiency special surgical barrier cloth filters.
When we put a superior mask on a nursing home medical staff person, each mask can protect 12 – 20 elderlies from the nursing home staff person from bringing COVID 19 into the home, from the workers travels around town – back home … and then back in to work doing that most critical work of helping our precious elderlies.
Donating those 45 medical grade high-efficiency filtering special masks … to the key nursing home people …. can protect all several hundred residents of the home, by breaking just one link in the chain of COVID-19 transmission … by keeping both the nursing home workers safe, and the elderlies safe … 24 – 7 for 2 months.
and… you pay just $4 each for each of the 50 masks (just $200) … and reduce your shipping cost per mask to just
$1 a mask… ![]()
In that case … you just protected 200 nursing home residents .. for just about $1.50 each. ![]()

2. A second paradigm shift:
That same $50 shipping can be both… a bolt cutter that cuts the chain of COVID 19 infections … and a lever ….
The same $50 shipping could also ship 200 masks … simultaneously lowering your shipping cost per mask down to just 50 cents…. and you pay just $4.50 total per mask (versus $16 each for buying just 7)
… to put superb masks on 4 different nursing home’s personnel …. and then, your $50 shipping .. levers you into protecting 800 elderlies in 4 nursing homes for just $1 dollar a resident …. for less than $1000 total.
3’rd Paradigm shift:
That $850 total spent for 200 superior masks … to protect 800 elderlies for 2 months …. is far less than the cost of treating one sick elderly … for one day of Covid-19
4’th Paradigm shift:
We define ourselves …. and we define our society by our actions ~ Especially how we act in a crisis ~ … We define our culture & society …. by how we treat others in a crisis.
Some people & some cultures get clannish and go into full-on bunker-mode… selfishly hoarding stuff … caring only for us & ours … effectively shunning “them”.
Some people get personally nasty … viciously snapping & sniping at other people … harshly judging… and snapping-at people they never even met.

5’th Paradigm Shift
In times of crisis … some ~other~ people stretch grow and become so much more… (than the clannish hoarders – snapping at others).
Imagine 10’s millions of people across America …. stretching … to create the America we want …
and …. With that ….
We get to the heart of why I conceived this mask …designed this mask, got it produced by Maya women, who can now feed their extended families by sewing safely individually in their homes …. getting paid superbly as piecework… where each woman can literally make $1600 pesos a day sewing masks to protect 1,000 of needy pitiful Americans.
That’s why I worked over 540 hrs in just one month …. to create this opportunity for America & all of us …
to become who we really could be….

6’th Paradigm Shift:
I also set this up …. “Talking Aerosols” … with 40% of profits going to help the neediest people … putting masks on poor nurses … where again, a single well-placed mask, protects 10 – 20 people (back to breaking the chain of infection, to protect the nurses extended family sheltering back home) … and profits that are used to help & protect Yucatan’s poorest people & poorest elderlies.
=> Donating 100’s of Masks to the horribly under-supplied and under-funded Mexican govt’s public hospitals providing 100’s of masks for Mexican doctors & nurses so far to 4 hospitals who have none.
and
The 7’th Paradigm Shift…
We donate more masks than we sell …
… using the profits & donations from others … to masks on those who need them most…. changing the world for the people who have no voice … for the people who have no resources, let alone having no leverage …
Can you use your lever … of the $50 shipping…. to literally help 1,000’s … by protecting Mexican Doctors, Nurses & Mexico’s really desperate elderlies ?

= = = =
In that reality
Our little group: called “Talking Aerosols” … a group of just 7 … me and 6 wonderful Maya ladies sewing …. We have currently donated over 6800 masks, while selling less than 6000.
… Do you now see why I worked so long & so hard (18 hr days for 30 days straight) …. to make this possible?

Read on, MacDuff …
For people still afraid of touching things
… Consider the 3 following realities of supposed touch-smear transmission … versus talking (vibrating vocal cords) generated … highest-risk respiratory fine aerosols.
… Were all the risks … all the millions of transmissions…. just like the choir … just like aircraft carrier … just like on all the cruise ships …. and just like the 17 yrs of SARS-CoV-1 research has shown… caused by mainly generated by ordinary talking …. or were the millions of exploding transmissions due to fearful people’s claims of supposedly touching things …. ?
Notice that even the CDC has changed their tune… finally reporting that the PRIMARY mode of spreading COVID-19 :
” (COVID-19) spread is by primarily by asymptomatic infected people simply breathing, and talking, ”
https://www.cdc.gov/coronavirus/2019-ncov/hcp/infection-control-recommendations.html
” Once the patient has been discharged or transferred, HCP, including environmental services personnel, ~ should refrain from entering the vacated room ~ until sufficient time has elapsed for enough air changes to remove potentially infectious particles ~
(more information on clearance rates under differing ventilation conditions is available).
After this time has elapsed, the room should undergo appropriate cleaning and surface disinfection before it is returned to routine use.”
https://www.cdc.gov/coronavirus/2019-ncov/hcp/infection-control-recommendations.html#adhere
= = = =
Remember, just 5 minutes of loud talking => 104 coughs coughs worth of highly infectious fine aerosols… trapped inside – floating …. slowly circulating …. a swirling infectious invisible mist … for 4-5 hrs … persisting ~after~ the talker left the room

Then remember …. These fine aerosols are only STOPPED by wearing a superb mask.
= = = =
1’st Really Troubling Example:
At just one single, loud, choir practice very-early in the COVID-19 outbreak:
~ 45 singers infected … out of 60 singers
… from just ONE COVID-19 infected asymptomatic spreader… at a church choir practice in Washington
… EVERYONE used hand “sanitizing” gel as they entered… no shared music … and there was ~NO TOUCHING~ allowed …
~ Note that hand sanitizer is not going to save you from the toxic talking-aerosol mists. ~
Just loud vibrating vocal cords from singing … making easily 80,000 of the most infectious fine aerosols … from just ONE asymptomatic spreader. … Toxic fine aerosols breathed in by all the young people in the choir…
… No coughing … No sneezing … NO TOUCHING…
4 dead now …
Why? … Because the fine aerosol toxic-talking invisible mist … persists highly-infectious for 4-5 hours indoors … and gradually swirls out up to 30 ft indoors …
~ Note that “Social Distancing” cannot save you from the toxic talking-aerosol mists. ~
https://www.latimes.com/world-nation/story/2020-03-29/coronavirus-choir-outbreak
= = = =
2’nd Troubling Example:
How can we ignore … the YOUNG HEALTHY 550 US sailors on the USS Roosevelt aircraft carrier … all …. now very sick from COVID-19 coronavirus?
Do we really believe that 550 of our young, best, robust, highly-disciplined, highly-monitored servicemen & women… somehow ignored the rules on hand washing & hand sanitizing??
or … Were they breathing shared-air in below decks cabins & rooms … where just one asymptomatic spreader ~innocently~ TALKING for just 7 minutes … fills the room with over 10,000 highest-risk … highly-infectious fine aerosols … an invisible toxic mist that floats & swirls … invisible & dangerous … for the next 4 – 5 hours …. trapped indoors.
USS Roosevelt Crew Stricken by Coronavirus

= = = =
3’rd Troubling Example:
Remember all the Cruise Ship passengers … trapped in their closed cabins … breathing shared-air from the neighboring rooms, big common shared ventilation systems.
Notice that on pretty much every Cruise Ship with Coronavirus Outbreaks … it only took 1 infected asymptomatic spreader … talking … infecting others through his invisible but highly infectious fine aerosols … lingering … and spreading … highly infectious fine aerosols persisting 4-5 hours in the air that the infected person ~innocently~ talked into.
Do we really believe that the 70% infection rates from COVID-19 Coronavirus on Cruise Ships happened … because people somehow touched things, WHILE TRAPPED IN THEIR CABINS ?
Do we really believe that ship’s kitchen staff were so clumsy, touching things without washing hands …. licking their fingers … sneezing on the food & plates (not) … magically caused the continuing devastating Coronavirus spread among the quarantined passengers … stuck in their cabins …
or…
Do we believe the top Epidemiologists who say that there has NOT BEEN EVEN ONE CASE of someone catching COVID-19 from food prep, nor from touching food containers ??
Not one proven case from food prep or touching food containers.
but 1
0,000’s of cases proven transmissions by Respiratory Aerosols … from TALKING.
= = = =
Were all the risks … all the millions of transmissions…. as Coronavirus EXPLODES, despite CDC advice …. Were the millions of transmissions from “touching things” or ….
Have they been just like the choir … just like aircraft carrier & Cruise ships … and just like the 17 yrs of SARS-CoV-1 research has shown… The PRIMARY transmission (96%?) comes from fine aerosols mainly generated from talking…
… Just 5 minutes of loud talking => 104 coughs coughs worth of highly infectious fine aerosols…
Fortunately…. Almost ALL of these highly-infectious fine aerosols from talking can be STOPPED by wearing a superb mask.
Why not wear a home-made mask? … or Cheap mask? … or 3D Printer fake-N95 mask?
We breathe in as many as 4000 highly infectious fine aerosols ~with every breath~ through a CHEAP MASK … or fake-N95 3D printer mask … or homemade mask …. just from stepping inside a closed room, where just one infected asymptomatic spreader, talked for just 7 minutes… 3-4 hours ago.
Remember…. 10,000 highly infectious fine aerosols … from just 7 minutes of a loud talker…
lingering as an invisible mist … 4 – 5 hrs later…
“ Putting it into different words…
Would you give (donate) to someone you love … a car with almost no brakes … ?
The (home*made mask) free car goes fast and looks really good
… but … with no brakes… it has really ugly consequences … when we need to stop. ”

People in Mexico, Canada, USA and anywhere DHL ships … can get superb medical-grade masks … re-washable up to 70 times … by sending me an email steven.m.fry@gmail.com
Please describe where you are, where you need the masks, what sizes, and how many you need-want.
We offer substantial volume discounts for 100-lots of masks. … especially if you agree to donate them to people in need, medical personnel, old folks homes, and on & on & on.

After 3 months of giving completely wrong, hazardous, too-often-fatal advice … the CDC has finally changed it’s tune…
“… coronaviruses spread is thought to occur mostly from
person-to-person via respiratory droplets ”
Click to access caring-for-patients-H.pdf
Aerosol scientists, 17 yrs of SARS-CoV-1 and the last 2 months of SARS-CoV-2 scientific testing, and top Virologists have all been saying the the PRIMARY risk from catching Coronavirus (COVID-19) is from breathing in fine aerosols from coughs, sneezes, & talking … These fine respiratory aerosol droplets ( ≤ 1 um diameters) from … infected Asymptomatic Spreaders talking without a mask … float around inside rooms … as a swirling invisible mist … with over 90% infectious potency after 3 hours …
These fine aerosols, primarily produced by talking … are the particulate-aerosols-droplets MOST easily breathed deep into our throats & lungs … going right through homemade masks & leaky flat masks …. (that leak 4000 aerosol particulates out of 10,000 total from someone talking in a room in the room during the past 4 hrs without a mask) … prove the risks of inhaling fine droplets ≤ 1 um in size.
Side Note:
A good mask filter material only leaks 3 out of 10,000 of these most risky fine aerosol respiratory droplets that the CDC warns about … while an N95 mask leaks 500 of them.
https://yucalandia.com/2020/04/08/coronavirus-update-how-to-avoid-or-prevent-your-most-risky-exposures/
~ Stay well, stay informed, stay safe. ~
So … What is an ordinary person to do … besides getting a fine high-function mask?
Seriously … Think of an old-time castle … and the layered Castle-defenses.
1. The moat (a good mask) blocks general entry … makes it difficult for invaders to get at the 2’n & 3’rd lines of defenses.
2. A GOOD STOUT WALL … aka the mucous layer in your nose throat and lungs … Keep it healthy, robust and strong… because that mucosal coating traps the virus particles, and temporarily blocks the Coronavirus from getting to target – mucosal lining cells underneath the mucous layer. **
3. Have a robust set of peak levels of Immune System compounds, waiting in the mucosal layer (protected by Vitamin C) … Superb levels of: Antibodies & Lymphokines and Immune System defense cells: Macrophages, Killer-T Cells (T-Lymphocytes), Dendritic Cells, White Blood Cells (Basophils & Eosinophiles) …. the key defensive components of our immune system, that attack and destroy the Coronaviruses … ready to RUMBLE, and take out the inhaled respiratory aerosol Coronaviruses …
https://yucalandia.com/2020/04/10/improved-coronavirus-covid-19-protection-by-consuming-vitamin-c/
**4. Have your nose, throat, & lung’s mucous layer system running at peak efficiency!
That means having …. ~ Thin watery mucous ~ …. coating your lungs, throat & nose … as your SECOND line of defense (behind your mask)
How do we get “thin watery mucous” ?
… Drink enough fluids until your pee is clear or only light straw color, to keep your mucous thin & runny …
Why do we want “thin watery mucous” ?
Because there are 10’s of millions of the cilia in your mucosal layer (10’s of millions little sweeper cells) ALL beating in unison … waving, whipping…. to sweep the virus particles out of your throat & lungs … to go past your epiglottis… and fall into your stomach to die immediately in the acidic low pH 2, due to stomach acids.. 😉
So, “thin watery mucous” allows the little sweeper-cilia cells to sweep the Coronavirus fine particulate aerosols… down into our stomach … to be destroyed by our stomach acid.
😉

Since the PRIMARY mode of Coronavirus (COVID-19) transmission is inhaling respiratory aerosols … Keep drinking, till your pee is clear… or only light-straw yellow color … to keep those sweepers, sweepin’…
and keep those immune system components … on deck … ready to rumble… when the virus hits.
😉

Eating Enough Vitamin C to Keep Your Immune System at Peak Efficiency
During times of stress … and during Coronavirus spreading .. We need a daily consumption of 500 mg – 1000 mg. total of vitamin C … split into at least four (4) … 125 mg doses …. each about 4 hours apart. Taking a single Vitamin C supplement pill in the morning just doesn’t work, because we pee out ~eliminate through urination~… the Vitamin C about 4 hrs after eating it.
500 mg – 1,000 Vit. C a day is necessary during stressful times to protect your already stress compromised immune system, specifically higher levels of Vit. C throughout the day … to protect our highly-important immune compounds ~ responses that fight Coronaviruses …
By taking enough Vit. C, the Vitamin C acts a “body-guard” molecules throughout your body to protect critical … Antibodies & Lymphokines and Immune System defense cells: Macrophages, Killer-T Cells (T-Lymphocytes), Dendritic Cells, White Blood Cells (Basophils & Eosinophiles) …. the key defensive components of our immune system, that attack and destroy the Coronaviruses … But note…. These immune system components need protection, by their own body-guards, so they don’t get ruined before they can do their job.

Sadly, all of these critical immune system components are all damaged or ruined by the consequences of viral attacks on our nasal, throat, & lung lining (mucosal lining) cells. When the virus causes the death of our mucosal layer cells … the dying cells lyse (apoptosis) and split open, releasing lots of nasty free-radicals, nitric oxide & harmful oxidants… chemicals that damage or wreck our immune system’s Antibodies & Lymphokines and Immune System defense cells.
To protect these most important immune system components, they need a powerful-but-proven-safe anti-oxidant “body-guard” molecule, like Vitamin C. … Vitamin C reacts within nano-seconds to neutralize the free radicals, oxidants & nitric oxide & cell death products => protecting our critical Immune System components, allowing them to do their jobs of killing viruses & bacterial invaders.
Why eat Vitamin C?
Only 2 kinds of creatures on earth need to eat dietary Vitamin C … Primates ( including Humans) … & Red Vented Bul-bul birds (and other birds). … Why? … All other animals evolved to make it themselves, but because we primates have evolved over millions of years, with lots of fresh fruits & veg in our diet, we don’t make it ourselves… and we must EAT Vit C every day …. Pigs make their own Vitamin C, Goats, Cats, Dogs make their Vitamin C…. but we have to eat FOODS CONTAINING Vitamin C, about 4 times a day.

~ Stay well, stay informed, stay safe. ~
Four (4) doses of Vitamin C @ 125 mg per dose, requires the following amount of foods, 4 times a day.
Servings (as cups) every 4 hours of Vitamin C … Vit C Content …. mg / serving
10 cups – Apple (manzana) = 12 mg. (1 cup raw)
12 cups – Avocado (aguacate)=10 mg (1 cup raw).
1½ cup -Brocoli = 81 mg (1 cup raw)
1¼ cup – Cabbage (repollo) = 93 mg. (1 cup raw)
2 cup- Cantaloupe (Melon Chino) = 57 mg (1 cup serving)
2/3 cup- Chaya 180 mg (1 cup serving)
… a super-food with 7 g protein, 300 mg Ca, 10 mg iron,1357 units Vitamin A, (1 cup raw)
2½ cup – Grape fruit (toronja)= 50 mg (whole)
1/3 cup of Guava (guayaba)= 373 mg (1 cup raw)
1½ cup – Kiwi = 93 mg (1 cup raw)
3 -Lemon = 44 mg (whole)
4 – Lime (Limon)= 30 mg (whole)
2 cup – Mango = 60 mg (1 cup raw)
2 – Orange (Naranja) = 58 mg (whole)
1 cup – Orange Juice (Jugo de Naranja) = 125 mg (1 cup)
2/3 cup- Pepper (pimiento rojo)= 190 mg (1 cup raw)
1¼ cup – Pepper -Green Chile (spicy) (ChileVerde) = 109 mg (1 cup raw)
1¼ cup – Papaya = 100 mg (1 cup raw)
1½ – cup – Pineapple (Piña) = 78 mg (1 cup raw)
2 cup – Potato (Papas) (Microwaved) = 72 mg
1¼ cup – Strawberry (fresa) = 100 mg. (1 cup raw)
Again, these portions are eaten about 4 times a day, to maintain good Vit C levels to fight the Coronavirus.
NOTE: Boiling any of these reduces Vitamin C by at least 50% … Microwaving preserves most Vit C.

The ≤ 1 μm fine aerosols from talking do not “fall” down to the ground …. They weigh less than 100 femtograms … so … They float & swirl & circulate for at least 4 – 5 hours … and they remain hazardous~infectious with 90% viral loads beyond 3 hours….
0.0000000000001 g = 100 femtograms… => an aerosol so fine, that it barely evaporates, even after hours of swirling around inside a room
These fine aerosols are so small & so-easily sucked deep into our throat & lungs by our normal breathing , that if you have any leaks or gaps around your mask (5% leakage for N95 masks and 40% leakage for cheap flat masks … and 70% leakage for home-made masks) , then these tiniest, invisible, most-infectious, highest-risk aerosols are swept around your mask … through your cheap mask … and DEEP into your throat & lungs…
Consider how we panic over just one 1 cough …. while a cough has just 60 of these fine aerosols…
While 5 min of normal-volume talking by a person without a mask … produces 104 coughs worth of these most infectious aerosols… 1500 Fine Aerosol Particulates for just 5 min of talking…
Our vibrating vocal cords are superb aerosol generators … and the Asymptomatic Spreader’s THROAT is putting-out peak amounts of virus during the 2 days before symptoms appear… dumping that throat virus-loaded mucous right onto our vocal cord fine-aerosol generators.
Note that these nastiest aerosols swirl & spread like mist … fog … slowly circulating out to 30 ft from the talker … CONTAMINATING a room for the next 4 – 5 hours…
Did anybody reading this notice that Social Distancing is DOES NOT WORK … not at all
… because these worst aerosols travel-swirl 20 – 30 feet from the talker … and the persist in a room … filling the room with contaminated infectious droplets …. circulating highly infectious for 4 – 5 hours … AND MOST MASKS DO NOT PROTECT AGAINST THEM…
Most masks leak too much … leaking in 4000 of the nastiest fine aerosols per 10,000 aerosols from an asymptomatic spreader – loud talker … who WAS IN THE ROOM 3 HOURS AGO…
Now, do we understand why compulsive hand washing, ~bleach spraying everything~ and “Social Distancing” are not working … They’re the wrong solution – that don’t work for this Coronavirus problem …. Instead,
Get a good mask!
The “95” in the N95 masks … means it leaks 500 of the worst nasty aerosols out of just 10,000 particulates …. INSTEAD A GOOD mask … made of surgical barrier cloth … like an N100 mask only leaks in 3 fine aerosols per 10,000 … and yes, our immune systems & respiratory mucous membranes EASILY HANDLE 3 fine aerosols…
So on a relative scale, your N95 mask is leaking 500 contaminated most-infectious aerosols, out of 10,000 ( 8 COVID-coughs worth ) … while a good surgical barrier cloth mask leaks only 3 particulates…
To protect your family & friends …
Open the attached diagrams … read them carefully… and consider ordering some masks

Why have CDC & WHO been unable to control the pandemic spread of COVID-19 Coronavirus disease?
Ironically, the real cause of the SARS-CoV-2 transmission has been know for the last 3 months by scientists, but the CDC & FDA officials have been promoting their own non-scientific personal false beliefs that SARS-CoV-2 virus is somehow a bacteria (supposedly not a virus) , insisting on their totally mistaken idea that the UPPER RESPIRATORY COVID-19 virus is supposedly transmited by fomites, from touching things.
SARS viral research since 2017 has shown that the real infectious transmission threat is airborne floating aerosols… from talking … vocalizing … or wheezing. Our vocal cords vibrate vigorously when we talk … flipping off 100’s to 10,000’s of tiny tiny fine aerosol droplets (1 um & smaller) … go out our mouths … and float in the air … highly infectious … for at least 3 hours when trapped inside rooms…
This is not the problem:
People talking, without tight-fitting medical grade N-95 or better masks, emit over 104 COVID coughs worth of fine aerosols, by talking loudly for just 5 minutes . … Invisible, highly infectious invisible aerosols from people talking or singing are the problem … especially when talking indoors, where the highly infectious COVID fine aerosols continue to float, swirl & circulate out to 30 ft, over the next 4 hours.
“Asymptomatic Spreaders”
Think: COVID-19 infected people, walking around talking … with no symptoms … while their throats are making the PEAK amounts of SARS-CoV-2 virus, during the 2 days before symptoms appear.
For comparison …
1 cough = 60 highest risk – most infectious fine aerosol droplets
Talking Loudy for 5 minutes Creates the Most Highest Risk Aerosols:
Soft talking for just 5 minutes => 750 fine aerosol droplets
…. equals => 12 mouth-uncovered coughs …
=>750 fine aerosol droplets which are considered enough to infect others within 6 feet of you. …
Normal talking for just 5 min. => 1500 fine aerosol droplets
… equals =>25 mouth-uncovered coughs
LOUD talking for 5 min. => 6,000 fine aerosol droplets
…equals => 100 uncovered coughs
Those 750 or 1500 or 6000 fine aerosol droplets float around inside rooms … for over 3 hours … remaining highly infectious the whole 3 hrs … spreading within 30 ft indoors of the infected speaker.
What Can we Do?
Wear a tight fitting medical grade mask** when inside public places… Need to eat or drink? => Have a fan or a breeze blowing fresh air across your face, to disperse ~ dilute~out fine aersols to safe levels …. Have conversations without masks when outside with 8 ft of Social Distancing, where the wind – breezes blow away your fine aerosols from talking (dilution) …
Then consider the special 1 in 50 people who are … “Super-emitters/Super-Spreaders”
The Super-Spreader people >= spew 15,000 fine aerosols in 5 minutes of LOUD talking
… equal to 250 uncovered-mouth coughs … in just 5 min of talking.
Think about all those invisible floating droplets … when walking into an OXXO minimart …. or in a combi bus … or any small enclosed space like a bank ATM room …. because the fine aerosol droplets slowly float, swirl & circulate between 6 meters – 9 meters … filling an OXXO … for the next 3 hours … with the worst, riskiest highly-contagious aerosols … so small that they are inhaled deeply into our throats – slipping around all masks with leaks…
Cloth masks … are proven to leak at least 40% to 70%, because it takes at least 12 layers of cloth (16 layers of cotton cloth) to equal just one good medical grade mask. … Do NOT trust a cloth mask.
**Note that good surgeons & Aerosol Scientists often wear 2 masks for the best protection, in the most critical situations. Wearing a flat, tight fitting good medical grade mask tight against your lips & nose acts like a condom, to protect an outer cup-cone N95 or KN95 mask. The combination of 2 masks seals much better around the nose & cheeks than one mask, giving full 99.9% levels of protection with both medical grade masks fit tightly.
Now do we understand why CDC’s & WHO’s advice to NOT wear masks… is exactly why Coronavirus has spread so quickly in the USA ?
Then, consider the Medical Doctor’s guess of “6 feet of Social Distancing”. The “6 ft Rule” only works if the talking-person’s invisible aerosols move out in all directions, evenly, at the same rates (like some diffuse mist or fog). Instead, scientists have proven for over 40 yrs that fine aerosols, when there are no fans or breezes, fine aerosols move exactly like cigarette smoke, moving outward in plumes – streams of concentrated aerosols … invisibly floating slowly out 8 ft to 10 ft, like forked-tongues, from the infected talker who is not wearing a medical-grade mask … until they disperse to safe-to-inhale levels at 8 – 10 ft when there is fresh air. That means the scientific rule is … 8 – 10 ft of Social Distancing, plus fresh air, when you have your mask off, like when eating or drinking.
Fortunately, all the facts above have been known by scientists, from 2 years ago to 16 yrs ago, by their reading ALL the very good scientific research done on SARS-CoV-1 & on other Coronaviruses.
Read the details at these websites:
https://www.nature.com/articles/s41598-019-38808-z
Aerosol emission and superemission during human speech increase with voice loudness
and
If you doubt these facts, consider the choir practice where just one COVID-infected singer, infected 60 other choir members … from them inhaling the sick-singers fine aerosols from talking & singing.
Touching things presents near infintesimal risks of transmitting COVID, because it takes roughly 1000 coronavirus particulates DEEP IN YOUR THROAT or Nasopharynx – which ONLY happens from inhaling aerosols …
Touching things … “fomite” or contacts as described by AS SEEN ON TV Medical Doctors is NOT THE PROBLEM … unless you collect an entire COVID sneeze’s goo and swab it deep into you throat. … It’s all about NOT inhaling COVID infected invisible fine aerosols.
~Stay safe ~
… Wear only a good medical grade mask … to protect yourself & others from COVID-19.
… If you don’t have a medical grade mask, like when eating or drinking, then stay 8 ft of Social Distancing from others (to allow the COVID fine aerosols to disperse to safe levels) … or have a fan blowing across your face to dilute the COVID aerosols from talking to safe low levels.

March 29, 2020
Have you considered why all our our efforts. and our authorities’ efforts are not working to stop the spread of COVID-19 ?
Can you imagine being able to see the invisible aerosols that we sneeze-out, cough & spray while talking?
How would you act, if you saw that the person just 1.5 m away from you … was spraying 1,500 ~highly infectious~ fine aerosol droplets … floating ~ swirling invisible … circulating out … up to 30 feet … as clouds of 1 micron (um) droplets … from just 5 minutes of talking …
How would you change your ways if you saw those clouds of 1 um ~highly infectious~ fine aerosols … 50 COVID-coughs worth – up to 117 COVIID-coughs were being BREATHED IN … with every breath … by everyone within 10 feet … even those wearing simple home-made masks … up to 5 hours … after the infected-person left the building ?
How would you change your ways … If you saw that those clouds of ~highly infectious~ fine invisible floating aerosols … were STILL in the room … 3 hours later …
Floating, swirling as each person walks by … infectious for 3 hrs … swirling & circulating inside the room for a full 3 hours … Lurking … waiting… invisible for people WITHOUT MASKS to walk in, and breath them deep into their lungs.
Does ” Social Distancing ” still sound like ‘THE Solution’ **
… when a LOUD TALKER who is shedding shocking amounts of Coronavirus into their throats …. in the 2 days BEFORE symptoms … peak amounts of SARS-CoV-2 virus into their throats … in the mucous … ON THEIR buzzing vibrating VOCAL CORDS … spewing out up to 15,000 highly-infectious fine aerosols
in just 5 minutes of talking…
Now … Do we see why the Coronavirus keeps spreading…. ?
because all the months of CDC and ” As SEEN on … TV ” Talking Head ‘experts’ … (aka Medical doctors) … do NOT know Aerosol Science nor airborne virus transmission ….
because all the months of CDC and ” As SEEN on … TV ” Talking Head ‘experts’ … (aka Medical Doctors) … advice on
~ Hand Washing … Gel … bleaching EVERYTHING… and “Social Distancing” … are basically TOTALLY ineffective … at stopping or protecting us from the PRIMARY COVID-19 risks … from invisible aerosols from TALKING
… moving out 30 ft … for 5 hrs … indoors…
= = = =
All the HANDWASHING in the WORLD … does not protect you at all from breathing in those 1,500 – 15,000 fine highly-infected aerosols floating infectious, circulating around inside a room … from just 5 minutes of talking by someone who was there 3 hrs before you arrived…
ONLY a good mask … that blocks, stops, catches all those 1,500 – 15,000 tiny fine TALKED aerosols … each weigh just 0.0000000000005 grams … so they do NOT fall onto counters or clothing like the big majority of coughed & sneezed droplets…
This means just 5 minutes of TALKING not only generates as many total droplets as an open cough …. TALKING generates 25X times more of those dangerous fine aerosols that we breath in with every breath …
~ 25X more highly infectious fine aerosols …. than an open cough … from normal volume talking ~ that linger lurk circulating in the room for the last 3 hours…
~ Stay well, stay informed, stay safe. ~
**Social Distancing does help protect you from the big heavy spitted droplets from messy talkers, from coughs & sneezes …. but Social distancing of 1.5 meters puts you RIGHT IN THE TARGET ZONE of the Corona virus talker’s fine highly-infectious aerosol clouds….

SO … Either stay home …** or
Only talk with other people in slightly breezy conditions OUTSIDE where the fine aerosols are quickly blown away … diluted out … to harmless levels..
or
WEAR A GOOD MASK … with proven N-95 materials … a mask that seals well …
to protect yourself … and others …. from the clouds of highly infectious fine aerosols spewed by talkers…
A good mask …. Protecting you as you walk through the grocery store …. from those 1500 fine aerosols … floating around infectious from the previous 3 hrs of people talking in that area that you just walked into…
and yes… There are YEARS of good aerosol science and high quality virology work that prove these troubling realities:
**Coronavirus Incubation Times & Times to onset of symptoms:

“A new study calculates that the median incubation period for COVID-19 is just over 5 days and that 97.5% of people who develop symptoms will do so within 11.5 days of infection.”

The Science behind the Coronavirus Spread by Talking Problem:
The scientific Aerosol Science results are conclusive:
“1. The particle emission rate during speech is linearly correlated with the amplitude (loudness) of vocalization, for four different languages tested.
2. The particle size distribution is independent of vocalization loudness or language spoken.
3. Some individuals (…. the mysterious Super Spreaders of Coronavirus …) emit particles at a rate more than an order of magnitude larger (10 times more) than their peers, i.e., they behave as “speech superemitters.”
https://www.nature.com/articles/s41598-019-38808-z
Notice GRAPH “D”
Loud talkers make 4X times more fine high-risk aerosols than soft talkers … Normal volume talkers making 2X times more fine high-risk aerosols than a soft talker.

The next article describes how long Corona virus lasts on surfaces, and in the air…
“Transmission of SARS-CoV-2, which causes COVID-19, has quickly outstripped the pace of the 2003 SARS epidemic. “Superspread” of the earlier disease arose from infection during medical procedures, in which a single infected individual seeded many secondary cases. In contrast, the novel coronavirus appears to be spread more through human-to-human transmission in a variety of settings. ”
HOW LONG DOES THE Coronavirus hang around in our homes?
“(Scientists) found that SARS-CoV-2 (in fine 1 um aerosols) was largely stable through the full 180-minute test, with only a slight decline at 3 hours. ”
“The researchers then tested the viruses on a variety of surfaces for up to 7 days, using humidity values and temperatures designed to mimic “a variety of household and hospital situations.” The volumes of viral exposures that the team used were consistent with amounts found in the human upper and lower respiratory tracts.”
“The novel coronavirus was most stable on plastic and stainless steel, with some virus remaining viable up to 72 hours (3 days). However, by that time the viral load had fallen by about three orders of magnitude, ”
Scientists found “the two viruses (SARS-CoV-1 and SARS-CoV-2) differed in staying power on copper and cardboard. No viable SARS-CoV-2 was detectable on copper after 4 hours or on cardboard after 24 hours. … “

TODAY’s FUN FUN Updates ! 3/26/20
It’s …. ” ~ Clearing up MISCONCEPTIONs Day ! ~ ”
Misconception #1:
Coronavirus (or any upper respiratory virus) is somehow magically handled like in the same ways you protect yourself from the “24 hr flu” (aka bacterial food poisoning) … imagining that Coronavirus is somehow magically like protecting yourself from Salmonella, fecal coliforms (pooh bacteria), Campylobacter, Listeria and other FOOD CONTAMINANTS … Fortunately … Coronovirus is completely different from bacteria … and the ways you protect yourself are very different from defeating GI-pathogenic bacteria.
Why?
Coronavirus DOES NOT REPLICATE on a surface …. It just slowly degrades ~ dies . So time is on your side…. as the viruses outside our mouth, throad & lungs … dry-out & die out ! … over time. … Time is on your side !
Table of SARS-CoV-2 Coronavirus Median Half-Life Times on Surfaces
| Surface | SARS-CoV-2 (hr) | SARS-CoV-1 (hr) |
|---|---|---|
| Copper | 3.4 | 3.76 |
| Cardboard | 8.45 | 1.74 |
| Steel | 13.1 | 9.77 |
| Plastic | 15.9 | 17.7 |
Notice that it takes 4 half lives for 94% of the viruses to die off…. and just 6 half lives for a 98.5% of a virus to die off… Just 1.5 out of 1000 viruses are alive after 6 x Half Life … Fortunately … at those low levels … the small amounts of remaining viruses (after 4 – 6 half lives) are very unlikely to be able to infect a healthy person, even if they touch the contaminated surface … and IMMEDIATELY stick their finger in their eye, nose, or mouth…
That’s why wearing even a simple paper mask can BREAK THE CHAIN of infection … because even the simple mask BLOCKS the finger-lickers & booger-pickers from sticking their fingers into their noses, and mouths. … and the simple paper mask catches the sneezed-droplets ~launched at 220 mph~ … & it catches the cough launched-droplets at 60 mph … and catches our spitted-droplets from talking (pppp’s,,, ttt’s, ssss’s , fffff’s )
because 5 minutes of talking spews out the same 3000 droplets that a cough launches…
😉
Misconception #2:
Viruses magically reproduce & grown on surfaces, like Bacteria …
Reality… Viruses do NOT grow on surfaces … They die on surfaces.
So why do the CDC & WHO talk so much this past years about cleaning surfaces?
Notice that BACTERIA, like salmonella, fecal coliforms, et al … DO grow and reproduce on surfaces … living & expanding over time on surfaces… while viruses just slowly dry out and die on a surface … dead in 4 hrs on copper, 24 hrs on cardboard (cloth etc), and 2 – 3 days on plastic, steel & tile …
Then realize that the cleaning methods are DIFFERENT for Bacteria vs Coronavirus.
…. Bacteria are not really harmed much by soap … while SOAP DESTROYS Coronavirus … and TIME destroys Coronavirus.
Educate yourself on the KEY DIFFERENCES ….
Corona virus is spread by SNEEZES, COUGHS, & TALKED viruses …sprayed aerosols of SPIT & SNOT … spread by people NOT wearing their little paper masks…. Wearing a mask, catches your 5 minutes of aerosol spit droplets from talking, that equals one COUGH…
3,000 spit droplets from talking for just 5 minutes IS primarily HOW THE CORONAVIRUS is spread by the people who are COVID-19 infected but have no symptoms…
WEAR A MASK … when around others … because you don’t want your ppp’s & bbb’s & tttt’s & ssss’s sprayed droplets floating around for hours…
~ Stay well, stay informed, stay safe. ~
= = = =
“Among patients infected with SARS-CoV-2, viral loads in the upper respiratory tract are high; as a consequence, respiratory secretion in the form of aerosols (<5 μm) or droplets (>5 μm) is likely, the authors note. ”
https://www.medscape.com/viewarticle/926929?src=soc_fb_200318_mscpedt_news_mdscp_surfaces&faf=1&fbclid=IwAR3iAooxQu5JmujwedyCbrTUsHD0xxbddMcl4iEa4AxafmPRI8aFdFVtx2g
The SCIENTISTS (not medical doctors) … found that SARS-CoV-2 was largely stable ~contagious~ in the air … through the full 180-minute test, with only a slight decline at 3 hours. … SO … IGNORE the WHO … IGNORE the CDC … MASKS WORK ! … to stop the virus spread.
MISCONCEPTION #3:
Sadly, the WHO Medical Doctors & CDC Medical doctors have been MISTAKENLY telling people that masks supposedly “don’t work” … while scientists prove that masks DO WORK.
Sadly, Medical Doctors typically have only very limited scientific training on these things (Medical Doctors are NOT scientists) … and … Sadly, for the last 3 months the Medical doctors … and TV DOCTORS … and CDC medical doctors …. have mistakenly CONFUSED Coronavirus upper respiratory-specific virus transmission methods with common Gastrointestinal bacterial transmissions**
**Bacterial infections are SPREAD BY CONTACT ~ “smear” ~ touch … while viruses spread by aerosol droplets … which is why a MASK protects people from Coronavirus spread… by BREAKING the chain of infection… while mask wearing does little to stop bacterial spread…
**Bacteria spread by growing, and often ~ MULTIPLYING ~ on each new surface … While Coronavirus needs human cells to reproduce … by specifically hijacking our nose-lining cells … our throat-lining cells … and our lung lining cells … THAT’s WHY IT IS SO CRITICAL TO wash your hands before touching your eyes, nose or mouth.
MISCONCEPTION #4
” You can catch Coronavirus from: ”
~ petting the dog
~ your clothes
~ the food you bring home from the grocery store…
~ sitting with someone who is 2 meters away, with both people wearing masks…
Notice that all of these routes would require you touching the other person’s still-wet snot droplets or wet spit droplets … and then you would have to nearly immediately SMEAR that wet snot-spit droplet into your eye, nose or mouth ….
and…. the snot-spit droplet would have to come from a sick person actively shedding lots of virus … (in the 2 days before the fever & the 2 days after the fever)…
So, if a sick person sneezes onto your clothes, or onto your dog … then don’t smear their snotty infected droplets into your eye, nose, mouth or throat … Protecting yourself from contact-based “smear”-based Coronavirus transmissions … is as simple as washing your hands … before you stick your fingers into your eyes, nose or mouth…
Or … better still … rub your itchy eye or itchy nose with the back-of-your hand or with your wrist … or … Even better ? Wear a little paper mask … to block yourself from unconsciously inserting your fingers into your mouth, eye or nose…
No more finger-lickin’ … nose-picking behaviors … unless you want to infect yourself.

~ Stay well, stay informed, stay safe. ~
Misconception #5 …
I can get Coronavirus by someone touching my plate, or my food, or sneezing in my food…
REMEMBER
Corona virus selectively attacks just throat, nose & lung tissue linings is also why we have seen ZERO Coronavirus transmissions by food contamination NOR by food packaging contamination … because YOU ARE SAFE, unless you touch slimy sneezed snot droplets … and then touch your own eyes, nose, or throat, with their slimy snot …
” Many studies have shown that people expel aerosol particles containing potentially infectious microorganisms during coughing, speaking, or breathing (Fabian et al. 2008; Morawska et al. 2009; Stelzer-Braid et al. 2009; Lindsley et al. 2010; Fennelly et al. 2012) …
Droplets you eat .. vs droplets you breathe in…
Normal stomach acids digest the Coronavirus immediately … so almost always, the Coronavirus must touch the nasal-lining, throat-lining, or lung lining cells … to infect those target cells in you.
… There are NO … ZERO reported cases of eating food contaminated by Coronavirus, causing a COVID-19 infection … 😉
~ Stay well, stay informed, stay safe. ~
Aerosol Science of Sneezed, Coughed & Spoken (spit-talked) droplets
…. MOST (typically 95%) of the spit, coughed & sneezed droplets are big … and they fall harmlessly to the ground within 1.5 meters of the spitter, talker, cougher (2m) , or sneezer …

Then note that those 99.9% of large droplets & medium droplets from talking, spitting, sneezing, and coughing … are caught~trapped~blocked … by even the cheapest paper masks … SO WEAR A MASK when around others … to protect them… and you.
” … Current infection control guidelines distinguish between “droplet precautions,” which are needed for diseases thought to spread primarily by larger spray droplets, and “airborne precautions,” needed for diseases that spread via small aerosols (Siegel et al. 2007). Large droplets (greater than ~50 µm) are primarily affected by gravity; they follow a ballistic trajectory and impact on surfaces or fall onto surfaces within a meter of the source. Intermediate-sized droplets (~10–50 µm) can deposit by impaction but can also be carried further from the source by the cough air flow and can travel 2 m or more before settling. Small droplets (less than ~10 µm) are much less prone to impaction or settling; they can remain airborne for an extended time and be spread throughout a room by air currents, especially after drying (CDC 2006).
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4615563/
“The geometric mean of the (sneezed) droplet size of all the subjects is 360.1 µm for unimodal distribution and 74.4 µm for bimodal distribution with geometric standard deviations of 1.5 and 1.7, respectively. “
These sneezed (possibly SARS-CoV contaminated) droplets are HUGE and launched at upwards of 220 mph – so they are blasted into even the simplest paper or cloth mask …
https://royalsocietypublishing.org/doi/10.1098/rsif.2013.0560
Meanwhile, a coughed aerosol “has a size range of 0.1–30 µm, a VMD of 3.4 µm, and a GSD of 2.3. ” …
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4615563/
This big droplet effect is also why SOCIAL DISTANCING works … Almost ALL of the nasty persons spoken or sneezed droplets … fall harmlessly to the ground or onto some surface ( counter or phone )
It’s the fine aerosols less than 5 um … and especially those less than 1 um that are a problem – AND … a well-fitted N-95 mask blocks 99.8% of even tiny tiny 0.045 um fine aerosols.
So … Is it clear now … why the WHO & CDC medical doctor’s bad advice that “masks don’t work” … is neither scientific … nor is their advice true … 🙂
Wear your masks ! 😉

March 23, 2020 Updates:
If you have just the one well-fitted N-95 mask, what should you do?
Because the Republicans spent so much effort eliminating funding to so many disaster response programs (as the Dems did nothing), even at the beginning of the crises, weeks ago, we have had so few masks
… that US Nurses, Doctors & Firefighters have chosen to disinfect their masks, daily… re-using the same mask day … after day .. after day … after day … for the past weeks … because they decided a disinfected used-mask … is better than no mask. 😦
The result? Our healthcare professionals, nationwide, are STERILIZING their masks, and reusing them, daily … over and over and over …. because of critical shortages …
while the DINOSAURS in Washington DC (aka the FDA & CDC) claim that masks “should not be reused.”
Ordinary people … generally have an oven in their house … an oven that can heats consistently at warming oven temperatures 180ºF – 200ºF (88ºC) … Pretty much any solid object (except wax etc) can be safely completely sterilized by heating it to 180ºF … and baking it for 20 minutes at that temperature (no higher than 200ºF).

Notice that common Mexican gas ovens do NOT have a “warming oven” setting … Read details here:**
Dry Heat Sterilization:
THE standard for over 100 yrs:
Realize that you can sterilize coins, paper money bills … and even plastic bills, by spreading them out on cookie sheets and baking them for 20 minutes at warming oven temps (180ºF to 200ºF)…. We can also safely sterilize pretty much ALL paper & plastic items using this same technique.
Just like baking cookies proves that our ovens have hot spots & cold spots … the cookies do not all bake the same way at the ends of the sheet vs the centre … Notice that YOU MUST WATCH your first baking operation like a hawk … 
You don’t want to fry the plastic in your N-95 mask because your oven thermometer isn’t quite right, or because your oven has a hot-spot …
Watch the heating process carefully… to quickly open the door if your objects start to look different during heating.
I have successfully dry sterilized plastics, papers, bill, masks … and it WORKS … to get the OBJECT up to 175º F for 3 minutes (using a special professional lab-grade laser-temp gun heat pistol thermometer) … Aimed NOT through the glass … but through just air – with the laser pointer on the sterilized object.
Since not many people have a professional temperature gun, you may have to carefully slowly heat the oven to 180ºF … especially if it is a (generally crappy) gas stove oven …and only then put your precious item onto the preheated cookie sheet … and WATCH IT LIKE A HAWK …
Background Science:
Dry heat sterilization has been used for over 100 yrs, for sterilizing surgical instruments … for sterilizing solids …. per US APHIS protocols. … Sadly …. The CDC & FDA Medical doctors may have forgotten … but the scientists at USDA have known & published for over 50 years … that dry heat works for sterilizing soil and even sewage sludge samples…
Notice the broth in Pasteur’s flasks are still clear .. sterile … after 140 years … even with a tube that open to the air ..
So, if you are one who has no additional cases of N-95 masks … if you are someone who must reuse their well-fitted N-95 mask, then … know that dry heat sterilization at 180ºF – 200ºF (88ºC) in a simple warming over, for 20 minutes … kills all microbes on the surfaces of solids.
… and … those temperatures do not harm paper nor plastics.
**NOTE … DO NOT PUT ANY PAPER OR PLASTIC OBJECTS close to the electric heating element of ANY oven, especially your Toaster Oven….
and DO NOT PUT ANY PAPER OR PLASTIC OBJECTS close to the bottom plate of a gas oven, where the gas flames heat that bottom plate….
**Mexican Gas Ovens
Most Mexican gas ovens do NOT have temperature indications on the dial … and MOST Mexican gas ovens keep the burner ON constantly … ON too long for staying in the 180ºF to 200ºF range …
If you fire up your Mexican gas oven, and set the dial to it’s lowest setting… it still gradually automatically, uncontrolled … OVERHEATS to OVER 245ºF … I test-baked plastic & paper bills$$ at this temperature … and the plastic bills got a little bit shiny … but came out fine, even after OVER HEATING for 20 extra minutes…
SO … To STAY BELOW 200ºF (93ºC) … you need to use a decent oven thermometer … and open your oven door a little , to let out the hot air … briefly cooling the oven back to the 180ºF to 200ºF range … for 20 minutes of your stuff sitting on the cookie sheet.
In other words… PUT THE OVEN thermometer ON THE COOKIE SHEET … with whatever you are sterilizing…
~ Stay well, stay informed, stay safe. ~
Practical Considerations for Dry Heat Sterilizing solid items:
Notice that your solid paper item might be contaminated, so handle it with care, like how our professionals remove a dirty surgical glove, by grasping it at the uncontaminated edge … or using a gloved hand … and placing the contaminated solid object either in the trash … or on a metal cookie sheet for sterilizing at 180ºF to 200ºF temperatures for 20 minutes …
Fortunately, 180ºF to 200ºF is not that hot … so things do NOT burn … just like keeping your medium rare steak warm – to relax the meat, … while but not cooking it further ….
Things at 180ºF – 200ºF cool quickly … and are safe to handle within minutes after opening the warming-oven door.
Keep your paper & other solid objects safe … watch them carefully as you bake them in case your oven is not reliable.
March 22, 2020 Updates:
Why is it likely safer to get take-out food, or delivered (servicio a domocilio)?
Can you get COVID-19 from touching … or eating contaminated food?
Reality: There is no current evidence that COVID-19 has spread through food or food packaging.**
Remember this SARS-CoV-2 virus is transmitted primarily by contagious invisible airborne aerosols from sneezes, coughs and talking* … lingering in the air for up to 3 hours … SARS-CoV-2 is ~not likely~ transmitted by touching things, or by “smear” transmissions.
Realize that the COVID-19 disease virus in the back of that sick guys throat (when he has not symptoms) … does not magically jump into your eye, nose or mouth. …
*3 minutes of talking … Sssch-peak-ing consonants .. Popped P’s, schusshed Ssssss … B’s , T ‘s, Ffffs … ALL SPRAY as many fine aerosol droplets as a single cough … up to 3,000 droplets sprayed by talking … where the big majority of talked aerosols are the BIG droplets that fall to the ground or onto the counter …

That’s why Social distancing of 1.5 protects you (and me) from their sprayed-talked aerosols…
It’s NOT the pizza guy making you a salad … It’s the person your standing too close to, as they gesticulate & pop-their-P’s, and hiss-their-Ssss’s … and THAT’s why it’s courteous to wear a surgical mask, to catch ALL of your coughed, sneezed, and TALKED aerosol sprayed-droplets.
Notice that even the CDC finally, after months of mistaken reporting and factually false announcements, .. finally the CDC changed, and reported last week that sprayed AEROSOLS … invisible, contagious sprayed by talking, sneezing, coughing ARE THE PROBLEM. … which is why masks & social distancing are important.
https://www.cdc.gov/coronavirus/2019-ncov/prepare/transmission.html

**Can I get COVID-19 from touching or eating contaminated food?
Seriously, there no current evidence that COVID-19 has spread through food or food packaging
Multiple health & safety organizations worldwide, (inc. the CDC, the USDA, and the European Food safety Authority), report that
” there is no evidence that COVID-19 has spread through food or food packaging. “
… Coronoavirus is primarily transmitted by AIRBORNE aerosols …
and possibly – but highly-unlikely by sneezed, coughed & talked-aerosols that land on surfaces. So you are safe touching things … unless you touch the contaminated aerosol on the counter, pizza box, etc … and then put your finger in your eye… or pick your nose.
It’s ALL up to you …
Don’t sneeze on Grandma or Grandpa …
… Stop putting your fingers in your mouth … Use the back of your hand or wrist to rub your eye or nose…. and WASH YOUR HANDS … before touching your face.
Whistle Yankee-Doodle … twice, while scrubbing your hands with soapy suds… 😉
Seriously … Previous coronavirus epidemics (SARS & MERs) … showed no evidence … of having been spread through food or packaging.
ENJOY !!!
but … Keep your distance from that guy who spits as he is talking
Do NOT shake that guy’s hand … who sticks his finger in his mouth.
Do not grab your change … $$money$$ from the cashier, and then rub your eye, or touch your nose…
Wash your hands after touching possilby nasty things … or sanitize (with gel) … before going into an at-risk person’s home … Care for our beloved Diabetics, elderlies, cardiology patients.
and NO … COVID-19 disease is not transmitted by pooh – fecal matter … unless you touch poo and then touch your eye …. 😉

March 20, 2020 Updates
Superb quality reports are saying:
Digestive symptoms, including diarrhea and anorexia, are common in COVID-19 patients (data from China). Hubei Province reports almost 50% of coronavirus patients reported digestive symptoms as their main symptoms.
… Just like the months of CDC’s & talking head Medical Doctors on TV … very mistaken public reported very wrong, very risky information about how COVID-19 disease is actually spread … and how the people without symptoms actually present “very low risks of COVID-19 transmission”, IF YOU TAKE PRECAUTIONS
Notice the facts that good scientists have reported for months:
The upper respiratory viruses are spread PRIMARILY by…. coughed, sneezed, and TALKED** aerosol droplets … That makes all the difference in how you protect yourself…
Notice that we reported how effective proper mask usage (cheap readily available surgical masks on sick people to catch their sneezed, coughed & TALKED** aerosol droplets – to protect everyone around them , and … use a well-fitted N-95 mask to protect at-risk HEALTHY people) can protect you and your loved ones….
~ Stay well, stay informed, stay safe. ~
= = = =
AND … Use dilute bleach to disinfect things (SANITIZING is not enough) … 4-6 tsps of Mexican laundry bleach (or 2 tsps of US 8.25% bleach) per 500 mL of water (make it fresh daily) … sprayed or wiped-wet onto surfaces to disinfect them …. and allow that surface to STAY WET (damp) for 10 minutes, to allow the bleach time to do it’s job…
and… regularly create “zones of disinfection” where you disinfect the pinch points … that are regularly unavoidably touched … car steering wheel, cell fone, keyboard, front door handles, car door handles … faucet handles … TV remotes … ~ fridge handles ~ … (read the other update details below) …
= = = =
Where to get good reliable information … update.
Notice that the Big Media’s Talking Head ‘Medical Doctors’ and the CDC’s medical gave months of very mistaken (very unnecessarily risky, bad) public advice about wearing masks …
Yes, the correct advice is to follow the German’s superb example … with their 0.2% death levels from COVID-19, versus the USA’s 20X times higher death rated … Appropriate mask use: USE Cheap readily available surgical masks on sick people to catch their sneezed, coughed & TALKED** aerosol droplets – to protect everyone around them , and … use a well-fitted N-95 mask to protect at-risk HEALTHY people.
Notice that not only did the Trump admin temporarily muzzle the CDC…. The CDC and the Big Media’s Talking Head ‘Medical Doctors’ sadly … gave very unnessarily-risky advice and bad non-scientific advice for months…
**Talked Droplets:
Each 5 minutes of talking makes as much aerosol as a cough …. making up to 3,000 droplets. … So … we have to assume 5 minutes of talking … IN CLOSE PROXIMITY … of someone creates about the same risk as their cough (with no surgical mask worn by the sick person to catch their coughed aerosol droplets) …
Close Proximity = less than 1.5 m between people … and up to 6 ft is the current standard.
Then notice the big majority of coughed droplets are large – shot out at surprisingly high speeds.. at distances of at least 1.5m … are heavy enough to land on a surface (like you) and remain contaigious for up to 3 DAYS on plastic & steel (and our local tiles) ….
Next consider that not even “talked aerosols” are equal to “coughed aerosols” … Notice the cough launches the droplets at higher speeds … so the big droplets go farther (landing further away) … landing further — requiring a bigger spraying of surfaces disinfection area (2m?)… while small aerosols (like from lisps and sss-sounds etc) …. float and move from the patient’s room out into the hallways … floating, contagious for up to 3 hrs … and then they land …. (far away) and possibly last dry, but contagious, for up to 3 days…
So … make up your dilute bleach disinfectant daily … and use it at-on all the affected surfaces, with special attention to frequently touched pinch points … maintain 1.5m social distance … wash hands (20 seconds of soapy suds … whistle Yankee Doodle twice) … and READ ALL ABOUT the rest of it … below:

March 18, 2020 Updates:
The latest scientific reports show that the SARS-CoV-2 (coronavirus) remains viable & infectious in coughed-sneezed aerosol droplets … in the air for up to 3 hours … and infectious on plastic & steel surfaces (and likely TILE) up to 3 days.
but … after 3 days on plastic, steel (or tile) … the remaining active viral counts had fallen roughly 1000X times from their initial sneezed-coughed values. AT THESE LOW LEVELS, it is very unlikely a healthy person would be infected, because their immune system should stop those very low levels of SARS-CoV-2 virus.
When the sneezed droplets land~settle on plastic & stainless steel, then viable virus was detected after three days. … On cardboard, the virus was not viable after 24 hours. … Even on copper, (a mild germicide), it took 4 hours for the virus to become inactivated.
National Institute of Allergy and Infectious Diseases (NIAID) research scientists found that it takes about 66 minutes for half the virus aerosol particles to become inactive.
https://www.niaid.nih.gov/news-events/new-coronavirus-stable-hours-surfaces
That means that by 132 minutes (66 more minutes), three quarters of the SARS-CoV-2 virus IN FLOATING DROPLETS … are inactivated … but 25% are still viable. … 3 hrs after the sneeze~cough … the droplet’s active virus levels are down to 12.5%.
Notice that after 3 hours, the sneezed virus droplets have very likely ALL settled onto surfaces, or and or dried out. … but the dry contagious aerosols (from sneezes) can swirl surprising distances, out of patient rooms & into the hallways, as a person opens the door – swirling the air.
Finally note …It takes 7 half-lives, after 8 hours … just 8 parts in 1000 (0.8%) of the active virus in those sneezed-deposited-settled droplets …
Why care?
Even if someone sneezes on the can of beans you bought at the store… that virus lasts a mere 3 days … TIME FOR SURGICAL MASKS on possibly sneezing grocery store shelf stockers?? … or have the grocery store stockers wear gloves? 😉
Why Surgical masks? Surgical masks catch up to 99.9% of sneezed-launched droplets…
Finally … Notice that the path to you becoming infected with COVID-19 disease … is a CHAIN … (just like a cold virus) … BREAK any link in the chain, and the SARS-CoV-2 virus does NOT get into your eyes, mouth, nose etc…
Disinfection & Personal hygiene are the key … Disinfect your PHONE! … Disinfect~Wipe that front door knob, don’t touch common surfaces (doors, counters, pens, light switches) that others touch … Don’t touch your face, hands, mouth …
Wash with soap & water to kill viruses, but soap & water don’t kill bacteria. => that takes hand sanitizer or dilute bleach**.
= = = =
Dilute bleach disinfectant … (4-6 tsps of Mexican bleach or 2 tsps of 8.25% US bleach in 500 ml of water) sprayed & wiped on surfaces (doorknobs, handles, counters, etc) is pretty important to breaking the COVID-19 chain …
For the very strong US versions of bleach with 8.25% Sodium Hypochlorite, use just 2 tsps of bleach per 500 ml of water.

March 14, 2020 Updates:
Fortunately, the latest research report out yesterday (READ IT … link above) … is saying the people without symptoms ARE NOT very contagious, at all…
As many of us scientists suspected weeks ago, and reported weeks ago… SNEEZED – COUGHED aerosol droplets are …. “the primary source of COVID-19 infections” …
That means the real risks are now know to be from ACTIVE sneezers & coughers with fevers.

and … It also means that sick people, sneezing & coughing can very-effectively KEEP THE REST OF US much safer, by them wearing a cheap surgical mask that are superb at catching their sneezes & coughs.
Their sneezes may produce as many as 40 000 droplets between 0.5–12 μm in diameter (Cole & Cook, 1998; Tang et al., 2006) that may be expelled at speeds up to 223 mph… (100 m/s )… which is what drives the sneezed droplets into masks …

The medical doctors (who have relatively little scientific training, and even less training in viral disease transmission) have sadly been spreading misinformation and false reports for a month… of other people supposedly catching COVID-19 disease from people without symptoms.
= = = = =
The fact that Mexican officials caught ALL of Mexico’s first 26 cases … as travelers returning with COVID-19, means … maybe … we can metaphorically stop it … or slow it way down “at the border” … “at the airport” … and minimize it’s spreading by RAPID EARLY TESTING… Testing that was NOT available in the USA for a full 6½ weeks. …
~ By having PEOPLE WHO TRAVEL immediately sequester themselves at the first signs of symptoms … we literally have SLOWED the SARS-CoV-2 virus transmission … to a crawl … with ZERO reported “community transmitted” cases during the first month of COVID-19 infections in Mexico. 😉
The Mexican Health officials are literally ALL OVER this … well prepared (compared to the USA) … and taking good appropriate actions … while the US public health experts remained in the dark for over 6½ weeks … with no accurate testing available… and US officials still complain they do not know how many COVID-19 confirmed positive patients there are because the US private labs are keeping their test data “secret”… … withholding the results from officials.

Staying Safe … & Keeping Loved Ones safe:
Handwashing?
Handwashing has been shown to be reduce your COVID-19 risks on your hands, to near zero, if you wash with soapy suds for 30 seconds, because while soap does little to kill bacteria … soap is VERY GOOD at de-activating viruses (by washing the virus’s fatty lipid protective coating off – exposing & damaging the underlying viral proteins) … 😉
Effective handwashing takes some surprising effort … 30 seconds
(whistle Yankee Doodle, twice) with brisk rubbing with soapy suds …
Hand-sanitizers?
Hand-sanitizer gel usage can be very effective IF the handsanitizer has over 60% alcohol…
Handling Money??
… Bake the money for 20 minutes** in a 200º F warming oven …
and Yes … That’s a proven old-school technique from the 1930’s => Dry Sterilization …
Why??
… BEST CURRENT EVIDENCE says “The COVID-19 disease’s SARS-CoV-2 virus can linger on surfaces for 2 – 3 days.”
**Notice that if an object is at 145º F (65º C) for at least 3 minutes, the heat kills all viruses & all bacteria and even Cryptoporids & their encysted spores. That means that if we spread the bills & coins out on cookie sheets in an already warm 200ºF warming oven – the bills & coins temperatures heated for 10 minutes, would easily exceed the 145ºF @ 3 minutes standard. … Since some people’s ovens may not be at 200ºF, and since some people may put in small clumps of bills, then 20 minutes at 200ºF gets typical clumps of bills upt to 145ºF for 3 mnutes.

GOING OUT of the House?
Me? … for now …. I’ll continue to go out
but, because my wife is extremely immuno-compromised from Lupus medications … I’ll be taking a few precautions.
1. … The 2m rule makes sense. People’s sneezes & coughs go into about a 6 ft radius … and the sneezed aerosol droplets can persist (float around) for up to 3 hours in that area.
This may be cause to wear a well fitted N-95 mask … in any area where people have coughed in the last 3 hrs.
2. Wuhan Corona virus (aka COVID-19) has just NOW been shown to last about 2 – 3 days on surfaces… 😉
“The scientists found that severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) was detectable in aerosols for up to three hours, up to four hours on copper, up to 24 hours on cardboard and up to two to three days on plastic and stainless steel. The results provide key information about the stability of SARS-CoV-2, which causes COVID-19 disease, and suggests that people may acquire the virus through the air and after touching contaminated objects.”
https://www.niaid.nih.gov/news-events/new-coronavirus-stable-hours-surfaces
3. SOAP disrupts the lipid (fatty) coating on virus molecules … and literally inactivates the viral proteins – so the virus molecules are no longer contagious – NOT transmittable after contact with soap.
4. People may have COVID-19 for as many as 14 days without showing any symptoms – gradually spreading their virus to surfaces and to things they touch during that 14 days.
4. a. … Those surfaces touched by the COVID-carrier, then can remain contaminated for 2 – 3 more days.
That results in an apparently healthy person contaminating things they touch (counters, door handles, fruits, veg … COINS … BILLS ) contaminating things unknowingly for up to 17 days.
5. #4 means that about anything you touch from being out in public … during the next 20 – 30 days … could be contaminated.
6. #3 means that you can either use soap to wash your fruit, veg & counters… and STEERING WHEEL on the car when you go out … and CAR DOOR HANDLE … gear shift knob-lever, etc.
Avoid big crowds … knuckle-bump … fore-arm bump …open doors with your butt or forearm~elbow …
Do your best to not touch your face…
Me? … I plan to wash hands before eating and … every time I leave home & enter home – to get into a habit ~ routine. ..
… After going out, plan a a few minutes of cleanup time** … Use dilute bleach (1 L spray bottle with 4 teaspoons of bleach … 1 part bleach in 50 parts water) … Backtrack to the car … Wipe ~ Disinfect doorknobs, light switches, the car door handle, the steering wheel, gear shift knob … the driver’s door interior handle.
Then either wash fruit & veg & coins in soapy water… or in a 5 minute VERY dilute bleach solution (just 10 drps of bleach in 1 L of water. … rinse coins & fruit w/ water…
7. I personally like using very dilute bleach versus soap, because soap only does less than ½ the job. Soap DOES NOT KILL BACTERIA, like SALMONELLA … soap only de-activates viruses … Soap also does not kill our common parasites …
Instead the dilute bleach solutions kills:
~ kills parasites, their eggs, etc.
~ kills amoebas
~ kills paramecia
~ kills cryptosporids & their cysts (like giardia)
~ kills bacteria
~kills viruses…
😉
8. Because of the 17 day window of well-meaning infected people (with no symptoms) transmitting their illness to bills, & coins … I’ll be gently baking our cash in a warming oven – for 20 minutes at 180ºF to 200ºF … => superbly proven dry disinfection that kills EVERYTHING…
Dry disinfection at less than boiling water temps is a proven approach for sterilizing surgical instruments … for sterilizing soil samples (US-APHIS protocols) …
Just like 175ºF has been used for PASTEURIZING FOODS …. killing everything, for the last 160 yrs. 😉.

Why ignore the mistaken medical doctor’s advice?
Are you really at risk from infected people who have no symptoms?
Yes, the day before they have symptoms & the day that symptoms start have their viral loads peaking, and with high viral shedding rates IN THEIR THROATS.
How does those high levels of SARS-CoV-2 virus, shed into their throat … get into your eyes, nose, mouth … if the asymptomatic person is NOT coughing & NOT sneezing?
There are chains of successive events, where the sick-os lick their fingers, pick their noses, contaminate their hands … and then touch things that you touch.
Break any link in the chain, and you stay safe.
= = = =
What can you do about it:
If we don’t disinfect that door handle, airline-counter, glass, plate, grocery store checkout counter .. the credit card the clerk handled … the shopping cart handle ,,, then the virus can remain viable, contagious … for up to 2 -3 days.
Then … you have touch that thing … the thing that the finger-licker, nose-picker touched …. and then you have to touch your own eye, nose or put your finger in your mouth … contaminating yourself.
Work to break those chains … pay a bit of attention to your personal habits & personal hygiene …. to keep yourself, family & loved ones safe.

Instead the dilute bleach solutions kills ALL of it:
~ kills parasites, their eggs, etc.
~ kills amoebas
~ kills paramecia
~ kills cryptosporids & their cysts (like giardia)
~ kills bacteria
~kills viruses…

Interesting Research Results from Yesterday, Friday the 13’th…
Estimated median incubation times (IT) for COVID-19 is 5.1 days; mean IT was 5.5 days.
For 97.5% of infected persons, symptoms appear by 11.5 days
Finally consider … the SARS-CoV-2 is just now proven to remain active-viable infectious … transmitting COVID-19 contagion … for 2 – 3 days on surfaces.
And yes … we can disinfect surfaces easily with dilute bleach (4 tsps of bleach in 1 L of water in a spray bottle) … or sudsy-soap inactivates-destroys the SARS-CoV-2 virus …
aka the virus that causes COVID-19 infections.

As USA has just recorded their first Coronavirus death …**
(and now … just 3 days later, the US Death Toll is up to 6)
How is the Wuhan Coronavirus (aka COVID-19) affecting the people we know & love?
Are you at risk? … What are the risks of death for Covid-19? … 2% ? … as reported by the talking heads of Big Media outlets?
What is your personal risk?
Curiously, as we consider men vs women, young vs old, healthy vs sick people … What about healthy people with underlying conditions – that are under control? … Diabetes? … Lung Problems? … High Blood Pressure?
What about people with immune system problems, or cancer … people who are being treated with steroids or other drugs suppress their immune systems, but who are currently living healthy lives?
Considering all those real world factors … realize that that no group on Earth has the “2% death rate” described by Big Media.
So far … The actual statistics are not quite what Big Media … FaceBook … and other people claim… Sadly, UNLIKE FLU …. COVID-19 infected people with ~no symptoms~ are shedding as much virus as COVID-19 people hospitalized with critical infections.
= = = = = = = = =
Sadly, unlike Flu … COVID-19 death rates are 46X – 75X higher than Flu, for the higher-risk groups … Cardiovascular disease patients … Diabetics … High Blood Pressure & people with respiratory (lung) problems ... people over age 60 … and Cancer patients & others with compromised immune systems.
= = = = = = = = =
Before we dive into the actual current (Feb. 29, 2020) COVID-19 statistics, consider this graphic:

Notice that depending on your age, you may take very different precautions.
Then consider the consequences that many contagious people with COVID-19 are infecting the people around them for a full 2 weeks … before they show any symptoms.
Even scarier: Some contagious people spreading COVID-19, never show symptoms.
“COVID-19 Fatality Rate by AGE:
*Death Rate = (number of deaths / number of cases) = probability of dying if infected by the virus (%). This probability differs depending on the age group. The percentage shown below does NOT represent in any way the share of deaths by age group. Rather, it represents, for a person in a given age group, the risk of dying if infected with COVID-19.

In general, relatively few cases are seen among children.
*Death Rate = (number of deaths / number of cases) = probability of dying if infected by the virus (%). This probability differs depending on sex. When reading these numbers, it must be taken into account that smoking in China is much more prevalent among males. Smoking increases the risks of respiratory complications.

Other Current Statistics on COVID-19
86,000 People are confirmed sick with Coronavirus at the moment across 47 countries,
of which 79,000 are in China. This means that if you are not in or haven’t recently visited China, this might reduce 94% of your concern.
If you do contract Coronavirus, this still is not a cause for panic because:
82% of the Cases are MILD
18% of the Cases are Serious or Critical …
Which means that even if you do get the virus, you are more likely to recover from it. … but … there have been 3,000 deaths out of 86,000 confirmed cases.
Latest data here:
https://www.worldometers.info/coronavirus/?fbclid=IwAR3uSe5VOzGNmgjA7o-JQ7pFXr5EAUeyrCJVRydCHLGbylzgZb1wpNhYSII
Some have said, “but this is worse than SARS !.
SARS had a fatality rate of 10% while COVID-19 has an overall fatality rate of 3.5%… but as we saw from the results above, your actual risks of death may be as high as 15%.
This means that:
if you are under 50 years of age and don’t live in China – you are more likely to win the lottery (which has a 1 in 45,000,000 chance).
Handwashing?
Handwashing has been shown to be reduce your COVID-19 risks from your hands, to near zero, if you wash with soapy suds for 30 seconds, because while soap does little to kill bacteria … soap is VERY GOOD at de-activating viruses (by washing the virus’s fatty lipid protective coating off – exposing & damaging the underlying viral proteins) … 😉
Effective handwashing takes some surprising effort … 30 seconds (whistle Yankee Doodle, twice) of brisk rubbing with soapy suds …
Hand-sanitizers?
Hand-sanitizer gel usage can be very effective IF the handsanitizer has over 60% alcohol…
Handling Money??
… Bake the money for 20 minutes** in a 200º F warming oven …
and Yes … That’s a proven old-school technique from the 1930’s => Dry Sterilization …
Why??
… BEST CURRENT EVIDENCE says “The COVID-19 disease’s SARS-CoV-2 virus can linger on surfaces for 2 – 3 days.”
**Notice that if an object is at 145º F (65º C) for at least 3 minutes, the heat kills all viruses & all bacteria and even Cryptoporids & their encysted spores. That means that if we spread the bills & coins out on cookie sheets in an already warm 200ºF warming oven – the bills & coins temperatures heated for 10 minutes, would easily exceed the 145ºF @ 3 minutes standard. … Since some people’s ovens may not be at 200ºF, and since some people may put in small clumps of bills, then 20 minutes at 200ºF gets typical clumps of bills upt to 145ºF for 3 mnutes.
https://www.livescience.com/how-long-coronavirus-last-surfaces.html
Further Examples … Notice that “Pasteurization” of foods & drinks has been proven for over 150 years … Pasteurization temperatures are 63º – 65º C for 30 minutes. … The 200º F (93º C) money-sterilization for 20 minutes very nicely exceeds typical ‘Pasteurization’ protocols. 😉
Wearing a Mask?
“That’s the problem … you should only be wearing a mask if you are sick.”
Notice that wearing a well-fitting N95 mask can keep BOTH the caregivers and the AT-RISK healthy patients (who have compromised immune systems or lung problems) … from inhaling over 99% other people’s sneezed droplets.
None of us want to inhale this gunk … floating around for hours. ![]()

Realities of Well-fitting N95 Masks versus stylish & chic Surgical Masks:
Sadly … Many talking heads on TV and even some Medical Doctors & Nurses are quoting results for leaky surgical masks … because as non-scientists, they aren’t familiar with the scientific test results – and they inappropriately substitute their knowledge of surgical masks (SM’s) in place of N-95 FFR mask performance.
Typical Doctor’s & Nurses surgical masks leak roughly 40% of the contagious sneezed aerosol droplets – through gaps around the nose & cheeks.
Surgical masks are designed to catch Doctor’s sneezes & Nurse’s coughs in the ER … to keep the patient safe from the Doctors & Nurses – protecting the patient … not the Doctor nor the Nurse.
Well-fitted N95 FFRs masks are INSTEAD designed to protect the patient from inhaling contagious sneezed aerosol droplets floating around in the air … protecting the wearer from inhaling 99.8% of small airborne liquid aerosol.
Again … Notice that a well fitted N95 mask is proven to block 99.8% of the contagious droplets sneezed~coughed by others.
Notice that both caregivers & people with lung problems or compromised immune systems … diabetes patients … cancer patients … and cardiovascular disease …. need well fitting N95 masks … NOT SURGICAL MASKS …
NOT this … These styles leak air around the nose & cheeks:

Instead, consider a well-fitting N95 mask, that has no gaps around the nose or cheeks, like this:

Proofs:
Tests using aerosols in the size range of sneezed droplets showed … two different N95 FFRs showed just 0.17% and 0.86% “Filter Penetration”… blocking even tiny 0.045 micron (um) aerosol droplets.
while the basic leaky Surgical Mask had 88.1% “Filter Penetration” …
For comparison, sneezed contagious droplets at 0.5 um – 12 um are much easier to block (stop from inhalation) than the 99.8% efficiency found for 0.045 um test aerosol droplets.
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4589201/
WHEN to Wear a Mask:
Virologists are saying that when a Coronavirus patient sneezes or coughs, it can be inhaled by people within a 6 ft (2 meters) radius … and within 10 minutes of the infected person sneezing or coughing.
That means anyone sick with COVID-19 should wear a mask, to catch their sneezed droplets, and anyone within 6 ft of an uncovered sneeze or cough can benefit from wearing a well fitting N95 mask.
Example: You’re in the grocery store line, and the infected person in line behind you sneezes, and the person in front of you coughs – you’re pretty jammed up, without a mask. … and if those people in line coughing & sneezing were wearing masks … the it’s a seriously good help for everyone within 2 meters.
Then … Consider the scientific study results for contagious viral transmission contact on a plane.
One sick person walking down the aisle to the bathroom is shown to potentially contaminate every single person they walk by (15 rows x 2 people on each side) – if they happen to sneeze or cough.
Well fitting N-95 Masks on the sick people, and on the people on the aisle seats … get help = protection from the masks.
That means that for all the contagious people with no symptoms, walking around, infecting others with COVID-19… it points to contact mechanisms.
Stopping Transmission that happens When We Touch Things:
Unfortunately, it means that we touch a surface that they touched, and then we (without thinking) we touch our face, nose or mouth … or casually rub our eye … or we touch a snack that we pick up.
Since Coronaviruses are shown to remain viable on surfaces up to 9 days … it points to some real risks we may not normally think about,
like touching a contaminated counter (at a bank, grocery checkout, or airport) … or touching the handle on a shopping cart or basket … or the grocery store cooler doors…or touch the keypad on a CC machine (to enter a PIN) or ATM keypad …
or touching money … that’s passed through many hands during the previous 9 days.
or worse yet … a shared keyboard at the nurses station or an ER’s tech-station ???
That perspective may mean re-thinking a bit about how we go through our days.
= = = = = = =
So, yes, even with washing hands (20 full seconds of soapy suds & aggressive-brisk rubbing to get a 25% reduced risk) … and a good N95 well fitting mask (reducing airborne respiratory virus to near zero) … we are still left with the risks of eye contact …
but hopefully, nobody sneezes into your eye.
Finally, Follow your doctor’s advice … If COVID-19 appears in your area, consider avoiding crowds and avoiding areas where previous people’s sneezes & coughs contaminated aerosol droplets linger in the air – and are transmitted by the building’s big air-handling systems (like on cruise ships) … and maybe even consider sterilizing your money (??)
If you or loved ones have loved-ones with pre-existing medical conditions … including suppressed immune systems, diabetes, cardiac conditions, respiratory problems, cancer, and even high blood pressure … consider restricting their visitors … and apply the same handwashing, hand sanitizer, & N95 mask protections for their caregivers – so the caregivers do not unknowingly challenge the patient with a Coronavirus infection that is not showing symptoms.
* * * * * *
Be well … Take reasonable precautions … Do your best to protect loved-ones with pre-existing medical conditions … including suppressed immune systems, diabetes, cardiac conditions, respiratory problems, cancer, and even high blood pressure.

Final Scientific Notes:
This means that direct intense sunlight … may kill SARS-CoV-2 on surfaces. 😉
but … the kill rates per exposure time have not been determined…
and …. the closer you are to the sun is REALLY key … the time of day (mid-day max UV) …. where high altitudes (5000 ft, 10000 ft, 12000 ft) and how close to the equator your are … give less air-atmosphere that absorbs UV ..
and the length of exposure to the sun’s UV-C light increases the DNA & RNA damage = harmful to both microbes & you => nasty cancer risks for humans out in the sun due to altering your skin’s DNA.
Shortest most intense pathlengths through the atmosphere, happen at mid day (look at your solar system output) … at high altitudes, and closer to the equator.
😉
= = = =
Published data have suggested that sneezing may produce as many as 40 000 droplets between 0.5–12 μm in diameter (Cole & Cook, 1998; Tang et al., 2006) that may be expelled at speeds up to 100 m/s (Wells, 1955; Cole & Cook, 1998), whereas coughing may produce up to 3000 droplet nuclei, about the same number as talking for five minutes (Cole & Cook, 1998; Fitzgerald & Haas, 2005; Tang et al., 2006). Despite the variety in size, large droplets comprise most of the total volume of expelled respiratory droplets.
https://www.ncbi.nlm.nih.gov/books/NBK143281/
In the classic study of airborne transmission, Wells (1934) was able to identify the difference between disease transmission via large droplets and by airborne routes. Wells found that, under normal air conditions, droplets smaller than 100 μm in diameter would completely dry out before falling approximately 2 m to the ground.
Droplet nuclei floating on the air may be carried by the movement of air. Entrainment of air into neighbouring airspaces may occur during the most innocuous daily activities; for example, as a result of people walking, or the opening of a door between a room and the adjacent corridor or space (Hayden et al., 1998; Edge, Paterson & Settles, 2005; Tang et al., 2005, 2006). In addition, the air temperature (and therefore air density) differences across an open doorway will also cause air exchange to occur between the two areas, providing a second mechanism to allow air into other areas (Tang et al., 2005, 2006) (see Figure C.3).
A higher air temperature directly above the patient’s head (or body, if lying down) will create convective air currents that may entrain potentially infectious air from neighbouring spaces into the higher temperature column rising air above the patient (Craven & Settles, 2006). Patients lying in bed, breathing or sleeping, may produce exhaled airflows that can reach the airspace of a patient in the neighbouring bed, and even further in the presence of certain types of ventilation systems (see below) (Qian et al., 2006).

For people considering where to buy property, and in what areas of Yucatan State foreigners can buy property without a Fideicomiso (real estate trust) … Notice that to get outside of Mexico’s 50 km Exclusion Zone limit for our shorelines, foreigners have to choose sites well south of Merida … all the way down & over to Acanceh … to get out of the 50 km restricted coastal zones.
Continuing East from Acanceh … Tahmek is just INside the 50 km zone … Kantunil is far enough south to be OUT of the zone … Continuing further east, Tunkás is just outside the zone… … Espita is the next town to the east, outside the zone … and then there’s not much east of Colotmul.

= = =
Next: Notice that Acanceh is about 28 km south of Merida … That means ALL of Merida is inside the 50 km restricted coastal zone (regardless of persistent gringo-rumors).
Valladolid is well outside the Exclusion Zone … about 40 km south of Espita.
Curious about other locals … check out this detailed map:
(when in the site … double click on the map, to make it BIG)

As of this moment … there are 60 countries whose citizens will be required to obtain an “ETIAS travel authorization” before entering the Schengen Zone** in 2021. Notice that the ETIAS-countries include USA, Canada & Mexico … plus Argentina, Australia, Brazil, Japan, New Zealand, and most of South America
Citizens of these countries will need to complete an online ETIAS application form to visit the Schengen Zone countries**.
… but NONE of the Republicans “Terrorist” travel ban states are included. … North Korea, Iran, Pakistan, Myanmar, Nigeria, Eritrea, Sudan, et al are ALL FINE … not needing the ETIAS travel authorization to enter Europe.

What countries are restricting entry in 2021?
**Think ~Europe’s Schengen Zone~ … Currently, that’s 22 EU member countries, four non-EU countries, plus three European micro-states.
**ETIAS registration will be required for Austria, Belgium, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Italy, Latvia, Liechtenstein, Lithuania, Luxembourg, Malta, Monaco, Netherlands, Norway, Poland, Portugal, San Marino, Slovakia, Slovenia, Spain, Sweden, Switzerland, and Vatican City.
Details:
Fortunately, the ETIAS online application form is quick & straightforward to complete. ETIAS travel authorization requirements require applicants to have a valid passport, a credit or debit card to pay the ETIAS fee, and an email address to receive their electronic ETIAS permit.
Applicants answer basic questions, including their travel itinerary, basic health history items, and descriptions of their criminal record. … Travelers details will be checked against security databases, like the Interpol and Europol databases & ETIAS email-approvals issued fairly quickly.
In a somewhat odd twist … Children under 18 (from ETIAS countries) must get an ETIAS visa waiver to travel to Europe.
Implementation Date:
The ETAIS rules were approved last July, 2019, describing a 2021 start date … but most recent ETAIS website updates now describe a “late 2021” kick-off.

This report is a heads-up to all the people who have been staying in Mexico by using a succession of 180 day Visitante visas … aka “tourist” visas. Since the Nov. 2012 publication of the Reglamentos (Regulations) by INM, INM officials have been moving slowly to restrict foreigners from living in Mexico on a 180 day Visitante visa, and then exiting Mexico briefly to try to re-enter on yet another new 180 day Visitante visa.
Since 2012, INM has had nationwide-computer access foreigner’s immigration records, documenting all of our exits and entries – in easy to look-up records, that allow them to identify people who clearly reside in Mexico, but who have not gotten Residente visas.
Along these lines … Recently, some INM officials have internally proposed implementing a policy of … a 90 day waiting period between 180d Visitante Visas … to stop foreigners from residing in Mexico, without getting Residente Temporal or Residente Permanente visas.
Will it happen?
Is it happening, now?
A recent internet report points to some INM agents cracking down on serial-successive Visitante visa usage – now including deportation back to the USA:
“I have only used tourist visas to stay in the country, and have never stayed past the 180 days the visa allows. On Thursday, I travelled back to Mexico through the Mexico City airport, but I was denied entry because they said I should have a resident visa. I was deported to Houston the next day (yesterday)“.
* * * * * * *
We have no special insights about where INM policies will ultimately land … but we offer this latest twist of sending AIRLINE PASSENGERS BACK to the USA … as a caution to people who have potentially overused 180 day Visitante Visas in the past.

A good friend just forwarded the following issue(s) … and question(s) on Facebook:
“Do you have experience with parasites?
I lived in Mexico for over a year recently with no health issues. Unfortunately I had to return to the US. I have been sick ever since I came back to the USA. “
” Has anyone had experience with parasites in your body? What were your symptoms?
I have bad gut issues, prostate problems and a bad UTI that will not go away. Doctors have no idea what’s wrong. … Thanks for any input.”
The FB friend commented~requested:
” Steve … I have seen some of your excellent comments you have made on similar (GI) problems. Trouble is the cooments and advice are difficult to locate now. How about sharing your wisdom with a column on gut health for expats? What meds should we be taking every six months? Appreciate your willingness to be so helpful to all of us expats! ”
= = = =
Whew … What a challenging set of issues.
GI Parasites … could be GI worms, amoebas, paramecia or even nasty-cryptosporids.
Sidelight: Since it could involve a wide range of problems, (too much to describe here) … SEE the Parasite treatment issues described at the end of this article.**
Continuing … In addition to parasites … also more broadly consider all the GI Microbes … most often E, coli … Salmonella (even becoming endemic), Shigella, Campylobacter (popular-common in the USA), rotovirus, the varieties of Clostridium (including “C. diff” ) …
General Advice on Prevention & Avoidance?:
Eat only well cooked meats …
e.g. Avoid ceviche … (the lime juice is NOT magic .. encysted worms & their encysted eggs are NOT affected by lime juice – it takes either cooking, or a sharp knife & good eye to eliminate them) … unless the people preparing the ceviche put thin sliced fish fillets on a light box & cut out the parasites – like what good sushi chefs do to protect their customers.
Eat foods with a peel: Bananas … apples … pears … Oranges & pretty much all citrus fruits.
Mexican Street-Foods: Eat what comes out of hot oil, and goes straight into a sterile piece of paper, cup, napkin etc, without being touched … (Continued in our main article on this at

Public Service Announcement:
We just got a request for some simple-but-proven ways to test the general water quality of your Merida City (JAPAY) water … or any chlorinated city water …. to determine if there is very likely ~no~ bacterial contamination in your home’s city water.
Here are 3 simple steps (tests) you can do at home:
1. Take a water sample at the city water meter for your house (or from a spigot close to the meter) and test that sample for “free chlorine” using a swimming pool tester.
… If the incoming JAPAY City water tests positive, for acceptable “free chlorine” levels … ( 0.4 to 1.2 ppm Free Chlorine) … then GREAT … there’s enough disinfectant to ensure no bacterial contamination.
2. Inspect the tinaco (and ground level cistern if there is one) … Make sure there is no accumulated detritus (leaves, dead birds, etc). If present: Remove any detritus & clean & disinfect the tinaco.

If the water in your tinaco looks clean & smells clean … then:
… Use your swimming pool chlorine tester to test the “free chlorine” levels in your tinaco water. … If the tinaco water tests positive, for acceptable “free chlorine” levels then GREAT … there’s enough disinfectant to ensure no bacterial contamination.
3. Go to your kitchen sink tap & bathroom sink taps (where you brush your teeth) … Use your swimming pool chlorine tester to test the “free chlorine” levels at your two main sink taps … If the sink tap water tests positive, for acceptable “free chlorine” levels then GREAT … there’s enough disinfectant to ensure no bacterial contamination.
Past testing of Merida JAPAY city water has shown that 3% of home’s meters had no free chlorine, and had fecal coliforms in the water coming through the meter. If this is true for your home’s meter, CONTACT JAPAY & file a complaint (there’s likely an underground leak in the pipes under the streets) …
Past testing of Merida JAPAY city water has shown that 26% of home’s kitchen sink water samples had no free chlorine, and had fecal coliforms in the water coming through the kitchen sink faucet. If this is true for your kitchen or bathroom sink … when your meter water tested positive for “Free Chlorine” … then you have significant contamination somewhere in your home’s plumbing.

If you have no free chlorine in your sink-tap water:
Typically, the in-home contamination comes from dead decaying organic matter (detritus) in your tinaco or cistern. … If your tinaco (and cistern) test positive for “Free Chlorine”, but your sinks do not have any “Free Chlorine” remaining in their water, then you need to clean your home’s plumbing.
After cleaning detritus from the system (organic gunk, like leaves, dead birds etc) … Then disinfect the home water system: Put ¼ cup of unscented laundry bleach into a standard 1100 L tinaco (300 gal) … to get swimming pool levels of free chlorine for the next 2-3 days.
If you want professional testing to determine the typical kinds of contamination found in Merida home’s water, then consider ordering one of the tests listed in this .pdf file:

If you want professional testing to determine the typical kinds of contamination found in Merida home’s water, contact one of our local water quality laboratories. Since we have had no experience with the current laboratories, we cannot vouch for the relative quality of any specific laboratory – but fecal coliform testing is a pretty simple & reliable test.
We welcome readers to volunteer (comment) on their experiences with any of our local water testing laboratories.
