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 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.
When should a face mask be worn
Consider wearing a face mask when you are sick with a cough or sneezing illness (with or without fever) and you expect to be around other people. The face mask will help protect them from catching your illness. Healthcare settings have specific rules for when people should wear face masks.
