The CDC recommends that people wear masks in public settings, at events and gatherings and anywhere they will be around other people. When you wear a mask, you protect others, as well as yourself. Masks work best when everyone wears one. A mask is NOT a substitute for social distancing. Masks should still be worn, in addition to staying at least 6 feet apart, especially when indoors around people who don’t live in your household.
Effective February 2, 2021, masks are required on planes, buses, trains and other forms of public transportation traveling into, within or out of the United States and in U.S. transportation hubs, such as airports and stations.
COVID-19 can be spread by people who do not have symptoms and do not know that they are infected. That’s why it’s important for everyone to practice social distancing (staying at least 6 feet away from other people) and wear masks in public settings. Masks provide an extra layer to help prevent the respiratory droplets from traveling in the air and onto other people.
The masks recommended are not surgical masks or N-95 respirators. Those are critical supplies that must continue to be reserved for health care workers and other medical first responders, as recommended by current CDC guidance.
More information about masks can be found on the CDC’s masks site.
