CDC recommends that you wear masks in public settings around people who don't live in your household and when you can't stay 6 feet away from others. Masks help stop the spread of COVID-19 to others.
Masks should be worn over the nose and mouth. Masks are especially important when it is difficult to stay at least 6 feet apart from others or when people are indoors to help protect each other.
Masks may slow the spread of the virus and help people who may have the virus and do not know it from transmitting it to others
Wearing a mask helps protects others in case you’re infected, while others wear one to protect you should they be infected.
