Masks overview

If COVID-19 spreads in your community, take some simple precautions to stay safe, such as physically distancing yourself, wearing a mask, keeping rooms well ventilated, avoiding crowds, cleaning your hands, and coughing into bent elbows or tissues. Check for local advice where you live and work. Do it!

 

For health care workers, medical masks are an essential piece of personal protective equipment when working with patients with suspected, probable or confirmed COVID-19. Respirator masks (e.g., FFP2, FFP3, N95, N99) should be used in environments where aerosol-generating procedures are performed, and proper sizing must be ensured.
