What does CO2 have to do with the risk of contamination indoors?

Every person exhales around 8-10 liters of air per minute, which is in intensive contact with the lung tissue. As a result, the exhaled air contains so-called aerosols and a high CO2 content of approx. 4% (40,000 ppm). Aerosols, which can contain contagious viruses, are so small that they only sink to the ground a few meters per hour. This means that the air in the room is polluted for a longer period of time.
If the CO2 content increases in a room, there are more aerosols in the room, which increases the risk of infection, as the possible concentration of four is higher.
At a concentration of 1200ppm (parts per million), a mass balance shows that around 2% of the room air has had lung contact at least once.
