A: If you are two years or older and unvaccinated, the CDC recommends you wear a mask in public indoor settings and around people who don’t live with you.

If you are fully vaccinated, the CDC recommends you wear a mask in public indoor settings in areas of substantial or high transmission (to maximize protection from being infected with the Delta variant and potentially spreading it to others.

The CDC states that those with weakened immune systems or living in households where someone is unvaccinated or at higher risk for severe disease may choose to wear a mask indoors at all times as well as in crowded outdoor settings.

If you are fully vaccinated and live in an area with a low number of people infected with the COVID-19 virus, the CDC indicates that you can resume pre-pandemic activities without wearing a mask or physically distancing, except as required by federal, state and local regulations, including local businesses and workplace guidance.

The CDC COVID-19 Data Tracker shows the level of COVID-19 transmission in communities throughout the U.S.

Currently, wearing a mask that covers your nose and mouth is required for travel on all public transportation including airplanes, buses and trains.
