Coronavirus spreads through the air

People infected with Covid-19 can transmit it to a room with tiny airborne droplets (aerosols) when they exhale, talk, shout, or sing.

Unfortunately aerosols are so small that we cannot see or measure them, but we also exhale CO2 (carbon dioxide) a byproduct of respiration that is easier to measure.

So the level of CO2 in a space can be used as proxy for the possible risk of exposure to Covid-19 to preventively refresh the air in the space.
