Isolation
Isolation is used to separate people with confirmed or suspected COVID-19 from those without COVID-19. People who are in isolation should stay home until it's safe for them to be around others. At home, anyone sick or infected should separate from others, or wear a well-fitting mask when they need to be around others. People in isolation should stay in a specific "sick room" or area and use a separate bathroom if available. Everyone who has presumed or confirmed COVID-19 should stay home and isolate from other people for at least 5 full days (day 0 is the first day of symptoms or the date of the day of the positive viral test for asymptomatic persons). They should wear a mask when around others at home and in public for an additional 5 days. People who are confirmed to have COVID-19 or are showing symptoms of COVID-19 need to isolate regardless of their vaccination status. This includes:

Ending isolation for people who had COVID-19 and had symptoms
If you had COVID-19 and had symptoms, isolate for at least 5 days. To calculate your 5-day isolation period, day 0 is your first day of symptoms. Day 1 is the first full day after your symptoms developed. You can leave isolation after 5 full days.
If an individual has access to a test and wants to test, the best approach is to use an antigen test1 towards the end of the 5-day isolation period. Collect the test sample only if you are fever-free for 24 hours without the use of fever-reducing medication and your other symptoms have improved (loss of taste and smell may persist for weeks or months after recovery and need not delay the end of isolation). If your test result is positive, you should continue to isolate until day 10. If your test result is negative, you can end isolation, but continue to wear a well-fitting mask around others at home and in public until day 10. Follow additional recommendations for masking and restricting travel as described above.

Negative results do not rule out SARS-CoV-2 infection and should not be used as the sole basis for treatment or patient management decisions, including infection control decisions. To improve results, antigen tests should be used twice over a three-day period with at least 24 hours and no more than 48 hours between tests.
Note that these recommendations on ending isolation do not apply to people with moderate or severe COVID-19 or with weakened immune systems (immunocompromised). See section below for recommendations for when to end isolation for these groups.
Ending isolation for people who tested positive for COVID-19 but had no symptoms
If you test positive for COVID-19 and never develop symptoms, isolate for at least 5 days. Day 0 is the day of your positive viral test (based on the date you were tested) and day 1 is the first full day after the specimen was collected for your positive test. You can leave isolation after 5 full days.
If an individual has access to a test and wants to test, the best approach is to use an antigen test1 towards the end of the 5-day isolation period. If your test result is positive, you should continue to isolate until day 10. If your test result is negative, you can end isolation, but continue to wear a well-fitting mask around others at home and in public until day 10.

Ending isolation for people who were severely ill with COVID-19 or have a weakened immune system (immunocompromised)
People who are severely ill with COVID-19 (including those who were hospitalized or required intensive care or ventilation support) and people with compromised immune systems might need to isolate at home longer. They may also require testing with a viral test to determine when they can be around others. CDC recommends an isolation period of at least 10 and up to 20 days for people who were severely ill with COVID-19 and for people with weakened immune systems. Consult with your healthcare provider about when you can resume being around other people.
People who are immunocompromised should talk to their healthcare provider about the potential for reduced immune responses to COVID-19 vaccines and the need to continue to follow current prevention measures (including wearing a well-fitting mask, staying 6 feet apart from others they don't live with, and avoiding crowds and poorly ventilated indoor spaces) to protect themselves against COVID-19 until advised otherwise by their healthcare provider. Close contacts of immunocompromised people - including household members - should also be encouraged to receive all recommended COVID-19 vaccine doses to help protect these people.
Isolation in high-risk congregate settings
In certain high-risk congregate settings that have high risk of secondary transmission and where it is not feasible to cohort people (such as correctional and detention facilities, homeless shelters, and cruise ships), CDC recommends a 10-day isolation period for residents. During periods of critical staffing shortages, facilities may consider shortening the isolation period for staff to ensure continuity of operations. Decisions to shorten isolation in these settings should be made in consultation with state, local, tribal, or territorial health departments and should take into consideration the context and characteristics of the facility. CDC's setting-specific guidance provides additional recommendations for these settings.
This CDC guidance is meant to supplement-not replace-any federal, state, local, territorial, or tribal health and safety laws, rules, and regulations.
