Except at home or with vaccinated covid-free friends, wear a mask... Aerosol....

I/we have known about the dangers of aerosol transmission since about this time last year,---many studies, demonstrations, etc.

Viral scientists have known for ages.... about the aerosol transmission of virus, or farts or cigarette smoke, etc etc...

Here is just one example- discussing, masks, time spent and ventilation efficacy.

Why is the CDC so often behind.....??
