Aerosols are a key transmission route for the coronavirus. The critical question remains: how much virus in these aerosols is needed to cause infection?
"The minimum infectious dose is unknown," note the researchers. Aerosols might cause milder symptoms than direct contact, but precautions are essential: keep elevator doors open longer, avoid talking or coughing inside, and prioritize ventilation.
