COVID-19: Prevention and Groups at Higher Risk

The best way to protect yourself and those around you from COVID-19 is to get vaccinated. If you are vaccinated, you may not need to follow all of the guidance below to stay safe. Learn more about the benefits of vaccination.

If you are not vaccinated, you can do your part to help prevent the spread of COVID-19 in NYC by taking a few steps every day. Remember, people who are at higher risk for severe illness from COVID-19 need all of us to help keep them safe, even after they are vaccinated.

Wear a mask
When you wear a mask, you protect people around you in case you are infected but do not know it. A mask can also help protect you from infection.

Masks are required for everyone in public transit, health care settings, schools and congregate settings, such as nursing homes and homeless shelters.

People who are unvaccinated must wear a mask in all public settings, indoors and outdoors.

People who are vaccinated are urged to wear masks in all public indoor settings, as well as in any setting when they do not know the vaccination status of those around them.

If you are at higher risk of severe illness, and particularly if you are unvaccinated, consider wearing two masks (a cloth mask over a disposable mask), which improves the fit and adds layers. You can also consider using a single higher-grade mask, such as a KN95 or KF94. This is especially important with the spread of the delta variant, which is much more contagious and may be more likely to lead to severe COVID-19 illness.
