For anyone still don't want to wear masks because you are told it wouldn't work or for other reasons, I just want to say, masks do work, just look at the countries in Asia where everyone wears it, the virus spreads slower there. It helps to protect everyone, the key point is asymptomatic people spreads the disease and we simply don't know who these asymptomatic people are, so we must all wear masks when we go to supermarkets and other crowed places if we have to be, very important!!!
