By now, it is just so obvious that COVID-19 is mainly an aerosol- transmitted disease, with minor fractions of surface and droplet transmission...

When will @WHO finally say this loud and clear, so ppl can protect themselves? (Like they did in 28-Mar saying "FACT: NOT AIRBORNE")

When, @gabbystern?
When, @mvankerkhove?
When, @DrMikeRyan?
When, @DrMariaNeira?
When, @DrTedros?

When will inconvenient science be finally accepted by @WHO?

How many infections will we have failed to prevent, by not explaining to ppl how it is really transmitted?

(Hint: >>1e6)

Please sign the citizen's petition to @WHO, for them to finally acknowledge that COVID-19 has an important component of transmission through the air (aerosols)

Glossary:
(1) "Aerosol" or "Airborne" transmission: an infected person exhales little balls of saliva or respiratory fluid. These "aerosols" contain viruses, and float in the air, like smoke (another aerosol). Infect in being inhaled. This is the dominant mode of COVID-19 trans.

(2) "Droplets": larger balls of saliva or respiratory fluid. Fly through the air like little cannonballs, infect by impact on eyes, inside of nostrils, lips or inside of mouth. Can infect if someone coughs or sneezes on your face. Otherwise not important, too scarce when talking.

(3) "Fomites" or "surfaces": can infect if a person touches an infected surface (door handle, phone, someone else's hand etc.) and then touches the inside of their own eyes, nostrils, or mouth.

@CDCgov said months ago that this is a minor mode of transmission, no one disagrees.

And we have to speak to the public clearly. Trying to explain control measures without explaining why they are needed has failed miserably, e.g. with ventilation.

Virologist @c_drosten (key advisor to Angela Merkel) says it most clearly:
