What is a face mask used for?

Facemasks help limit the spread of germs.  When someone talks, coughs, or sneezes they may release tiny drops (droplets) into the air that can infect others. If someone is ill a face masks can reduce the number of germs that the wearer releases and can protect other people from becoming sick.  A face mask also protects the wearer’s nose and mouth from splashes or sprays of body fluids.
