A growing collection of evidence and resources discussing the airborne nature of the SARS-CoV-2 virus, its impacts, and mitigation strategies.
Droplet vs Aerosols demonstration
“If you have an enclosed space with really poor airflow, those aerosols are going to fill up that room.”
Airborne particles stay floating in an unventilated room

A simulation of a cough sending tiny particles into an unventilated room, where they hover in the air for 20 minutes.
We know that breathing generates these particles as well.
The White House: Let’s Clear The Air On COVID
“The most common way COVID-19 is transmitted from one person to another is through tiny airborne particles of the virus hanging in indoor air for minutes or hours after an infected person has been there. While there are various strategies for avoiding breathing that air – from remote work to masking – we can and should talk more about how to make indoor environments safer by filtering or cleaning air.
In fact, research shows changing the air in a room multiple times an hour with filtered or clean outdoor air – using a window fan, by using higher MERV filters in an Heating, Ventilation, and Air Conditioning (HVAC) system, using portable air cleaning devices, and even just opening a window – can reduce the risk of COVID-19 transmission – with studies showing five air changes an hour reduce transmission risk by 50 percent. 1,2 And, improving indoor air has benefits beyond COVID-19: it will reduce the risk of getting the flu, a common cold, or other diseases spread by air, and lead to better overall health outcomes.”

The 60-Year-Old Scientific Screwup That Helped Covid Kill
“All pandemic long, scientists brawled over how the virus spreads. Droplets! No, aerosols! At the heart of the fight was a teensy error with huge consequences.”
