Wear a mask

If you have not received the full dose of the vaccine and are 2 years of age or older, you should wear a mask in indoor public places.

Generally speaking, there is no need to wear a mask in an outdoor environment.

In areas with a high number of COVID-19 cases, consideration should be given to wearing masks in crowded outdoor environments and in close contact with other people who have not been vaccinated at full doses.

If you have been vaccinated in the full dose and have a certain disease or are taking drugs that weaken the immune system, you may need to continue to take measures to protect yourself, such as wearing a mask. Please discuss with your healthcare provider what you can do to protect your health and deal with risks.

If you have been vaccinated at the full dose, please refer to After the full dose vaccinations.

You must wear a mask when traveling by plane, bus, train, and other public transportation into the U.S., traveling within the U.S. or leaving the U.S., and when you are in U.S. public transportation hubs (such as airports and stations). Travelers do not need to wear a mask in the outdoor area of ​​the vehicle (such as the upper deck of a ferry or bus). We recommend that travelers who have not received the full dose of the vaccine continue to wear a mask and keep their distance while traveling.

Keep 6 feet away from others

At home: Avoid close contact with patients.

If possible, maintain a distance of 6 feet from the patient and other family members.

Outside the home: Keep a distance of 6 feet from non-residents.

Please keep in mind that some people who have no symptoms may also spread the virus.

Keep at least 6 feet (approximately 2 arm's length) away from others.

Keeping distance from others is especially important for people at high risk of severe illness.
