Mask Wearing in the Community

Last updated May 23, 2023 at 8:05 AM

Masking is still an important tool for preventing the spread of COVID-19. Consider local COVID-19 case rates, your own risk factors, and your own comfort level with potential exposure to the virus to determine when and where to wear a mask.

Why wear a mask

Here are 3 reasons you might wear a mask:

  • To protect yourself. The most protective masks against viruses like COVID-19 are N95, KN95, and KF94 masks that have good fit and filtration. Masking in indoor public places is particularly important if you have an underlying health condition, are 50 or older, or have a weak immune system that increases your risk for severe COVID-19. It’s also important to wear a mask if you are caring for someone who is sick.
  • To protect others. Wear a mask when you are sick and have symptoms of a respiratory infection. Masks are also important for protecting vulnerable people in high-risk settings.
  • To follow local requirements. Be sure to follow any local masking rules in effect. Your local community facility or health center can require it.

When to wear a mask

Masks are recommended for everyone in indoor public settings when many in the community may currently have COVID-19 and be infectious to others. Please refer to your local health department for local data.

Regardless of COVID-19 case rates, masking is recommended:
  • If you have symptoms of a respiratory infection, such as a cough, runny nose, or sore throat
  • In crowded indoor settings, such as in airplanes, trains, and buses
  • In public areas around people who are older or have medical conditions that put them at increased risk for severe COVID-19
  • For 10 days after having a significant exposure to someone who has tested positive for COVID-19
  • If you have tested positive. See additional guidance at What to Do If You Test Positive for COVID-19
