Wearing a mask is one way to protect others, as well as yourself. Science shows that wearing a mask over your nose and mouth can help prevent transmission of the respiratory droplets and aerosols that spread COVID-19. Protect your loved ones, neighbors, and fellow community members by wearing a mask.
In areas with substantial and high transmission, CDC recommends that everyone (including fully vaccinated individuals) wear a mask in public indoor settings to help prevent spread of Delta and protect others.
Everyone should carry a mask with them when leaving home. If you are unvaccinated, a mask should be worn indoors, outside of your home when around non-household members, as well as in enclosed or crowded outdoor spaces, such as outdoor restaurants or bars, festivals, sporting events, and concerts. If you are fully vaccinated, you should consider wearing a mask when visiting unvaccinated people who are at increased risk for severe COVID-19 disease.
It is recommended in some settings, even if fully vaccinated, to continue wearing masks:
∙ Health care settings
∙ K-12 schools, including school buses
∙ Places where masks are required by local or tribal laws, rules, and regulations, including local businesses and workplaces
∙ Areas with substantial to high community transmission
∙ Correctional and detention facilities and homeless shelters
∙ All forms of public transportation (including planes, buses, and trains) traveling into, within, or out of the United States and in U.S. transportation hubs such as airports and stations.
People who are immunocompromised or are taking medications weakening their immune system may be at greater risk of infection 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.
Vaccinated and unvaccinated individuals don’t need to wear a mask in the following settings:
∙ Inside your home around your household members
∙ Outdoors where is it possible to maintain 6 feet of distance from others. (If you are unvaccinated and plan to attend an outdoor event or gathering with other unvaccinated people, even one where physical distancing is planned, a mask is recommended.)
∙ We understand that not everyone can wear a mask for medical or safety reasons (for instance, children under 2 years old and people who cannot safely wear a mask for reasons related to a disability). People 2 years of age and older who can wear a mask should do so to help stop the spread of COVID-19.
