1/ A sad anniversary: 1 year since one of the worst errors in the history of Public Health
SARS-CoV-2 is mostly transmitted through the air
But @WHO said, just a year ago, "FACT: IT IS NOT AIRBORNE"
And that saying it was airborne was "misinformation"

2/ We all make mistakes. But very important to correct them clearly
After saying loudly that virus only went through surfaces & large spray droplets, @WHO refuses to explain clearly that SARS-CoV-2 is airborne
Have NOT explained that their "FACT" of a year ago was a huge error

3/ It means that people don't know how to protect themselves, because they haven't explained clearly how virus is transmitted:
Like invisible smoke exhaled by the infected. We get infected by inhaling it
So ppl don't understand that indoors is dangerous despite distance

4/ And people don't understand that the more time indoors, the higher the risk of transmission.

5/ And although @WHO know does say clearly that ventilation is very important, they don't say why.
(Hint: ventilation does NOTHING for surfaces or large droplets, but helps a TON for airborne)
So many ventilate when no one is there. Or a few minutes every hour, not enough.

6/ And people don't understand that plexiglass barriers don't serve any purpose (except in a cashier / teller situation, then they do help).
7/ And people don't understand that the virus accumulates in indoor spaces.
And that one has to wear a mask at all times, if other people are going to come in. And that just putting the mask on when the other people arrive is not enough.

8/ And people don't understand that measuring CO2 is extremely useful to detect places and situations with high risk of transmission.
9/ As you just saw, it is not that hard to explain.
Why doesn't @WHO have drawings like these by @numeroteca in their webpage, tweets, Facebook etc.?
They don't explain it --> Ppl don't get it --> Ppl don't protect themselves well & get infected --> pandemic is not stopped

10/ Lots more details about the science and the history of the denial of and resistance to airborne transmission in the next thread.
#COVIDisAirborne, that (and transmission w/o symptoms) is why this pandemic is hard to control!
No acknowledgement ==> ineffective protection.
