Quarantine

Quarantine��is a strategy used to prevent transmission of COVID-19 by keeping people who have been in����with someone with COVID-19 apart from others.

Who does not need to quarantine?

If you had close contact with someone with COVID-19 and you are in one of the following groups, you��do not need to quarantine.

• You are����with your COVID-19 vaccines.
• You had confirmed COVID-19 within the last 90 days (meaning you tested positive using a��).

If you are up to date with COVID-19 vaccines, you should wear a����around others for 10 days from the date of your last close contact with someone with COVID-19 (the date of last close contact is considered day 0).����at least 5 days after you last had close contact with someone with COVID-19. If you test positive or develop COVID-19 symptoms, isolate from other people and follow recommendations in the����section below. If you tested positive for COVID-19 with a����within the previous 90 days and subsequently recovered and remain without COVID-19 symptoms, you do not need to quarantine or����after close contact. You should wear a����around others for 10 days from the date of your last close contact with someone with COVID-19 (the date of last close contact is considered day 0). If you have COVID-19 symptoms, get tested and isolate from other people and follow recommendations in the����section below.

Who should quarantine?

If you come into close contact with someone with COVID-19, you should quarantine if you are not����on COVID-19 vaccines. This includes people who are not vaccinated.

What to do for quarantine

• Stay home and away from other people for at least 5 days (day 0 through day 5) after your last contact with a person who has COVID-19. The date of your exposure is considered day 0. Wear a����when around others at home, if possible.
• For 10 days after your last close contact with someone with COVID-19, watch for fever (100.4◦F or greater), cough, shortness of breath, or other��.
• If you develop symptoms,����immediately and isolate until you receive your test results. If you test positive, follow����recommendations.
• If you do not develop symptoms,����at least 5 days after you last had close contact with someone with COVID-19.
  • If you test negative, you can leave your home, but continue to wear a����when around others at home and in public until 10 days after your last close contact with someone with COVID-19.
  • If you test positive, you should isolate for at least 5 days from the date of your positive test (if you do not have symptoms). If you do develop��, isolate for at least 5 days from the date your symptoms began (the date the symptoms started is day 0). Follow recommendations in the����section below.
  • If you are unable to get a test 5 days after last close contact with someone with COVID-19, you can leave your home after day 5 if you have been without����throughout the 5-day period. Wear a����for 10 days after your date of last close contact when around others at home and in public.
  • Avoid people who are have����or����from COVID-19, and nursing homes and other high-risk settings, until after at least 10 days.

After quarantine

• Watch for symptoms until 10 days after your last close contact with someone with COVID-19.
• If you have symptoms, isolate immediately and��.

Quarantine in high-risk congregate settings

In certain congregate settings that have high risk of secondary transmission (such as correctional and detention facilities, homeless shelters, or cruise ships), CDC recommends a 10-day quarantine for residents, regardless of vaccination and booster status. During periods of critical staffing shortages, facilities may consider shortening the quarantine period for staff to ensure continuity of operations. Decisions to shorten quarantine 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����provides additional recommendations for these settings.

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����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:

• People who have a����for COVID-19, regardless of whether or not they have��.
• People with����of COVID-19, including people who are awaiting test results or have not been tested. People with symptoms should isolate even if they do not know if they have been in close contact with someone with COVID-19.

What to do for isolation

• Monitor your��. If you have an����(including trouble breathing), seek emergency medical care immediately.
• Stay in a separate room from other household members, if possible.

Ending isolation for people who had COVID-19 and had symptoms

If you had COVID-19 and had��, 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.

• You can end isolation after 5 full days 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​).
• You should continue to wear a����around others at home and in public for 5 additional days (day 6 through day 10) after the end of your 5-day isolation period. If you are unable to wear a mask when around others, you should continue to isolate for a full 10 days. Avoid people who have weakened immune systems��or are����from COVID-19, and nursing homes and other high-risk settings, until after at least 10 days.
• If you continue to have fever or your other symptoms have not improved after 5 days of isolation, you should wait to end your isolation until you are fever-free for 24 hours without the use of fever-reducing medication and your other symptoms have improved. Continue to wear a����through day 10. Contact your healthcare provider if you have questions.
• See additional information��.
• Do not go to places where you are unable to wear a mask, such as restaurants and some gyms, and avoid eating around others at home and at work until a full 10 days after your first day of symptoms.

If an individual has access to a test and wants to test, the best approach is to use an��¹towards 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����around others at home and in public until day 10. Follow additional recommendations for masking and����as described above.

¹As noted in the����Negative results should be treated as presumptive. 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 who are moderately ill or very sick from COVID-19 or have weakened immune systems. 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��, 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 you continue to have no symptoms, you can end isolation after at least 5 days.
• You should continue to wear a����around others at home and in public until day 10 (day 6 through day 10).

Ending isolation for people who were moderately or very sick from COVID-19 or have a weakened immune system

People who are��moderately ill from��COVID-19��(experiencing symptoms that affect the lungs like shortness of breath or difficulty breathing) should isolate for 10 days and follow all other isolation precautions. ��To calculate your 10-day isolation period, day 0 is your first day of symptoms. Day 1 is the first full day��after��your symptoms developed. If you are unsure if your symptoms are moderate, talk to a healthcare provider for further guidance.

People who are very sick from COVID-19��(this means people who were hospitalized or required intensive care or ventilation support) and��people who have weakened immune systems��might need to isolate at home longer.��They may also require testing with a����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 very sick from COVID-19 and for��people with weakened immune systems.��Consult with your healthcare provider about when you can resume being around other people. If you are unsure if your symptoms are severe or if you have a weakened immune system, talk to a healthcare provider for further guidance.
