In April, the US Centers for Disease Control and Prevention recommended that all citizens wear nonmedical face masks to slow the spread of Covid-19. Wearing a mask not only protects you, it also prevents you from spreading noxious droplets should you be asymptomatically infected. It’s important to note, however, that wearing a mask does not exempt you from the routine of washing your hands regularly, staying at home when possible, and maintaining a 6-foot distance from others in public.
