Coronavirus Update … How to avoid or prevent your most risky exposures.



April 9, 2020

Is anyone wondering why the WHO advice and CDC advice has not been slowing the Coronavirus Pandemic spread? …. It’s because the medical doctor-politicians   have been ignoring the biggest factor … ignoring the most common form of transmission of SARS-CoV-2 Corona virus … invisible infectious mists of fine aerosols … from talking
… Highly infectious mists of fine aerosols … swirling .. floating for hours inside rooms … just from 1 asymptomatic spreader talking … slowly moving a meter … then out to 3 m,   then 6 m … and finally 9 meters … filling your local bank office, kitchen, mini-mart’s rooms   … Waiting for you to enter …
as the   toxic mists  from asymptomatic spreader-talkers & symptomatic talkers… lurk for hours … highly infectious. … Because those mists of the most infectious aerosols  ~ignore~  the CDC’s … “Social Distancing” rule.

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

Sincerely,

and yes… I did 3 yrs of aerosol science work … generating & wrangling & measuring these exact kinds of aerosol droplets – particulates… 😉

NEXT …  Spend some time with the crude-but fun diagrams below  … comparing the #’s of droplets,  … how long they last (3 – 5 hrs – virulent) …  How they threaten all our workers who work inside  & medical personnel … to see why the CDC’s efforts have failed.


~ And then … Enjoy your favorite bevvie  … out on the patio … with a good friend.~
Talking Aerosols - 1Talking Aerosols - 2
Talking Aerosols - 3
Talking Aerosols - 4Talking Aerosols - 5
Talking Aloud for 5 minutes Creates Far Far More of the Highest Risk Aerosols:Soft talking for just 5 minutes =>   750 fine aerosol droplets
…. equals => 12 mouth-uncovered coughsNormal 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

The Super-Spreader people >= spew 15,000 fine aerosols

… equal to 250 uncovered-mouth coughs … in just 5 min of talking.

 

Those 750   or 1500    or 6000    fine aerosol droplets float around inside rooms …  for over 3 hours  … remaining  highly infectious the whole 3 hrs.

      My sincerest apologies to you Martin … as I am just now reading your comment at 3:25 AM …

      and YES ,,, we have already raised over $28,000 pesos in direct donations for Yucatan’s poorest people… and we have handed out over 4000 free masks to poor people , Doctors & nurses…

      and yes … we have GIVEN AWAY more masks than we have sold.
