I am an expert in this audience has the correct answer..

I'm not an expert and I can only relay what I have either heard or read from the experts.........
The virus particles do not travel by themselves. The virus is carried by droplets and aerosols which are much larger than the virus. One droplet can carry thousands of virus particles in it. A cloth or disposable mask can easily block many droplets from escaping into the air from an aymptomatic or pre-symptomatic carrier of the virus. Even aeorsols can be blocked by a fabric or disposable mask.
Universal masking (meaning everyone wears a mask) can drastically slow the spread of this virus. In fact, I have read that universal masking with 80% compliance by our population can put an end to this pandemic within 2 months. And......that is without a vaccine. THAT is how effective covering the face is when in public.
