As for aerosol transmission, thank god COVID19 isn't as bad as SARS. So you have to be near infected to get it. The scientist can debate what's aerosol and what isn't aerosol all day long. Until COVID19 starts to spread within the building via HVAC or sewage throughout the building, I won't call it aerosol transmission yet.
