COVID-19 - face coverings; Coronavirus - face masks
In places where COVID-19 is spreading, wearing a face mask in public helps protect other people from possible infection with COVID-19. Other people who wear masks help protect you from infection. Wearing a face mask may also protect you from infection.
Wearing face masks helps reduce the spray of respiratory droplets from the nose and mouth. Using face masks in public settings helps reduce the spread of COVID-19.
The Centers for Disease Control and Prevention (CDC) makes recommendations about when to wear a mask based on the level of COVID-19 community spread. You can look up the level of community spread in your area on the CDC website.

How Masks Help Protect People From COVID-19
COVID-19 spreads most readily to people within close contact (about 6 feet or 2 meters). When someone with the illness coughs, sneezes, talks, or raises their voice, respiratory droplets spray into the air. You and others can catch the illness if you breathe in these droplets, or if you touch these droplets and then touch your eye, nose, mouth, or face.
Wearing a face mask over your nose and mouth keeps droplets from spraying out into the air when you are speaking, coughing, or sneezing. Wearing a mask also helps keep you from touching your face.

In these types of situations, staying at least 6 feet away (2 meters) from others is particularly important. Being outside can also help.

You can also talk with your health care provider to discuss other ways to adapt to the situation.
