Particle Size Of Covid-19 Droplets
These experimental results can be converted to demonstrate that, on average, 2.14 × 10−6% of a respiratory fluid particle of COVID-19 patients is occupied by SARS-CoV-2 and then the minimum size of a respiratory particle that can contain SARS-CoV-2 is approximately 32 μm.
How does COVID-19 airborne transmission occur?
There is evidence that under certain conditions, people with COVID-19 seem to have infected others who were more than 6 feet away. This is called airborne transmission. These transmissions occurred in indoor spaces with inadequate ventilation. In general, being outdoors and in spaces with good ventilation reduces the risk of exposure to the virus that causes COVID-19.

How long can COVID-19 linger in the air?
The smallest very fine droplets, and aerosol particles formed when these fine droplets rapidly dry, are small enough that they can remain suspended in the air for minutes to hours.

What does aerosol mean in the context of COVID-19?
aerosols: infectious viral particles that can float or drift around in the air. Aerosols are emitted by a person infected with coronavirus — even one with no symptoms — when they talk, breathe, cough, or sneeze. Another person can breathe in these aerosols and become infected with the virus.
