A member asked:

Does masks work on protecting us from covid? some sources say that even if masks are worn, it won't block droplets. is that true? if we go to a store or kids going back to school, everyone is at a really high risk even wearing masks?

A doctor has provided 1 answer

Yes, most masks are relatively worthless as cloth and paper will not block viral particles, airborne via droplets, as the virus is far too small. An N-95 respirator is far more protective but expensive and hard to find. Face shields would provide excellent protection in concert with the N-95.
