Reply to comment by Chi_Chi_laRue in WHO urges China to share specific data regularly on COVID situation by EagleEyes_009

The hospital taught you wrong (unless they were just talking about pathogens in general). COVID is spread by air, not by hands or dirty masks. Masks do help but only so much. If 80% of people around you in a subway car have COVID, the mask is probably not going to be enough.
