UPDATE
Given new evidence on the B.1.617.2 (Delta) variant, CDC has updated the
guidance for fully vaccinated people. CDC recommends universal indoor masking
for all teachers, staff, students, and visitors to K-12 schools, regardless of
vaccination status. Children should return to full-time in-person learning in
the fall with layered prevention strategies in place.
UPDATE
The White House announced that vaccines will be required for international
travelers coming into the United States, with an effective date of November 8,
2021. For purposes of entry into the United States, vaccines accepted will
include FDA approved or authorized and WHO Emergency Use Listing vaccines. More
information is available here.
UPDATE

WHAT YOU NEED TO KNOW

 * COVID-19 Community Levels help individuals and communities decide which
   prevention actions to take based on the latest information.
 * Each level helps convey how much COVID-19 is impacting your community using
   data on hospitalizations and cases.
 * Using these data, communities are classified as low, medium, or high.
 * For each level, CDC recommends actions you can take to help you protect
   yourself and others from severe impacts of COVID-19.

Many people in the United States have some protection, or immunity, against
COVID-19 due to vaccination, previous infection, or both. This immunity,
combined with the availability of tests and treatments, has greatly reduced the
risk of severe illness, hospitalization, and death from COVID-19 for many
people.

At the same time, some people—such as those who are older, are
immunocompromised, have certain disabilities, or have certain underlying health
conditions—continue to be at higher risk for serious illness. Learn more about
the factors that can affect your risk of getting very sick from COVID-19 to
better understand how COVID-19 could affect you and others around you.

For Healthcare Facilities: Prevention actions in healthcare facilities, such as
hospitals, rehabilitation centers, and nursing homes, are not linked to COVID-19
Community Levels.


KNOW YOUR COVID-19 COMMUNITY LEVEL

Take action to protect yourself and others from COVID-19 based on the COVID-19
Community Level in your area.

People may choose to wear a mask at any time. Masks are recommended in indoor
public transportation settings and may be required in other places by local or
state authorities.




INDIVIDUAL-LEVEL PREVENTION STEPS YOU CAN TAKE BASED ON YOUR COVID-19 COMMUNITY
LEVEL


LOW, MEDIUM, AND HIGH


AT ALL COVID-19 COMMUNITY LEVELS:

 * Stay up to date on vaccination, including recommended booster doses.
 * Maintain ventilation improvements.
 * Avoid contact with people who have suspected or confirmed COVID-19.
 * Follow recommendations for isolation if you have suspected or confirmed
   COVID-19.
 * Follow the recommendations for what to do if you are exposed to someone with
   COVID-19.
 * If you are at high risk of getting very sick, talk with a healthcare provider
   about additional prevention actions.


MEDIUM AND HIGH


WHEN THE COVID-19 COMMUNITY LEVEL IS MEDIUM OR HIGH:

 * If you are at high risk of getting very sick, wear a high-quality mask or
   respirator (e.g., N95) when indoors in public
 * If you have household or social contact with someone at high risk for getting
   very sick, consider self-testing to detect infection before contact, and
   consider wearing a high-quality mask when indoors with them


HIGH


WHEN THE COVID-19 COMMUNITY LEVEL IS HIGH:

 * Wear a high-quality mask or respirator.
 * If you are at high risk of getting very sick, consider avoiding non-essential
   indoor activities in public where you could be exposed.

recommendations

Science Brief: Community Levels and Making Public Health Recommendations


COMMUNITY-LEVEL PREVENTION STRATEGIES


LOW, MEDIUM, AND HIGH


AT ALL COVID-19 COMMUNITY LEVELS:

 * Promote equitable access to vaccination, testing, masks and respirators,
   treatment and prevention medications, community outreach, and support
   services.
 * Ensure access to testing, including through point-of-care and at-home tests
   for all people.
 * Maintain ventilation improvements.
 * Provide communications and messaging to encourage isolation among people who
   test positive.


MEDIUM AND HIGH


WHEN THE COVID-19 COMMUNITY LEVEL IS MEDIUM OR HIGH:

 * Implement screening testing in high-risk settings where screening testing is
   recommended.


HIGH


WHEN THE COVID-19 COMMUNITY LEVEL IS HIGH:

 * Implement healthcare surge support as needed.
