It is now recommended that you wear a cloth face mask in public places where social distancing is difficult like grocery stores and pharmacies, as people with no COVID-19 symptoms can infect others. Face masks are preferred over respirators and surgical masks, needed by healthcare personnel. Masks do not replace social distancing. The CDC provides instructions for making, using, and cleaning homemade masks.
