CDC — Your Guide to Masks
How to select, properly wear, clean, and store masks
- Everyone 2 years or older who is not fully vaccinated should wear a mask in indoor public places.
- In general, you do not need to wear a mask in outdoor settings.
- People who have a condition or are taking medications that weaken their immune system may not be fully protected even if they are fully vaccinated. They should continue to take all precautions recommended for unvaccinated people, including wearing a well-fitted mask, until advised otherwise by their healthcare provider.
- If you are fully vaccinated, to maximize protection and prevent possibly spreading COVID-19 to others, wear a mask indoors in public if you are in an area of substantial or high transmission.
