COVID-19 quarantine and isolation guidance


When do I need to Quarantine?

"Up-to-date" includes people who have received their booster shot or received the second Pfizer or Moderna vaccine fewer than six months ago or a single Johnson & Johnson vaccine fewer than two months ago. NOT "Up-to-date" includes people who are unvaccinated or not fully vaccinated; people who completed the primary series of Pfizer or Moderna more than six months ago but have not been boosted; or people who received a Johnson & Johnson vaccine more than two months ago and have not been boosted. Children younger than 16 years old (for whom booster is not recommended) are considered by the CDC to be "up-to-date". They should follow the guidelines below for someone who has completed their primary series and a booster.

I am not up-to-date with my vaccinations and booster and was exposed to COVID-19. What should I do?

If you are not up-to-date on your vaccinations and booster and have been in close contact with someone who has COVID-19 (within 6 feet of the person for 15 minutes or more over a 24-hour period), stay home without visitors (quarantine) for 5 days and seek testing on day 5. It's very important to test on Day 5 if possible.

If you do not have symptoms or test negative, after five days you can leave your home but must continue to wear a high-quality, well-fitting mask around others for five more days. If you can't quarantine you must wear a high-quality, well-fitting mask around others for 10 days, distance from others, avoid crowded places, and stay away from people at high risk for serious illness.

You can quarantine in your home or at a public Isolation/Quarantine center. Do not go to work, school, or public areas. If possible, also stay away from people in your household who are at high risk of serious COVID-19 illness.


I am up-to-date on vaccinations and boosters and was exposed to COVID-19. What should I do? If you are up-to date with vaccinations and boosters, after exposure to someone with COVID-19:

  • You do not need to quarantine following an exposure;

  • Wear a high quality, well-fitting mask around others for 10 days after the exposure; and

  • Test on day 5, if possible.

Everyone who has been exposed regardless of vaccination status should get a COVID test five days after exposure. If symptoms occur, individuals should immediately quarantine until a test confirms symptoms are not caused by COVID-19.

I tested positive for COVID-19 or have symptoms after being exposed. How long do I need to isolate? For all people who test positive, regardless of vaccination status, CDC shortened the recommended time for isolation from 10 days to five days.

  • If you have no symptoms, or your symptoms are improving after five days, you can leave your house. If you have a fever, stay home until your fever goes away.

  • You should continue to wear a high quality, well-fitting mask around others for five additional days.

  • High-quality and well-fitting masks are essential and are described here.

  • According to the CDC, they are making this change because data demonstrate that the majority of COVID transmission occurs early in the course of illness. CDC states that most transmission occurs in the 1-2 days prior to onset of symptoms and the 2-3 days after onset of symptoms.

While isolating, do not leave your home or public Isolation/Quarantine center, except to receive medical care. At home, anyone sick or infected should separate from others -- stay in a specific "sick room" or area, use a separate bathroom (if available), and avoid sharing personal household items. If you are in the same room as household members, make it brief, maintain a distance, and make sure you both wear a mask. What is the isolation and quarantine guidance for schools and other congregate settings? Does it differ from the general public guidelines? The Washington Department of Health is currently assessing certain setting-specific isolation and quarantine recommendations for non-healthcare congregate settings. In light of this, Washington Department of Health recommends that people in the following settings continue to follow the previous guidance and NOT the new guidance that was announced the week of 12/27 for the general public:

  • Schools and childcare

  • Commercial maritime settings such as commercial seafood and cargo ships

  • Crowded work sites where physical distancing is not possible due to the nature of the work, such as in warehouses, factories, and food packaging and meat processing facilities

  • Correctional facilities

  • Homeless shelters and transitional housing

  • Temporary worker housing

  • Institutions of higher education

I recently recovered from COVID-19 and was exposed to COVID-19. What should I do? If you recently recovered from a laboratory-confirmed COVID-19 illness past 90 days:

  • Stay home without visitors (quarantine) for 5 days and seek testing on day 5. It's very important to test on Day 5 if possible.

  • If you do not have symptoms or test negative, after five days you can leave your home but must continue to wear a high-quality, well-fitting mask around others for five more days.

  • If you can't quarantine, you must wear a high-quality, well-fitting mask for 10 days, distance from others, avoid crowded places, and stay away from people at high risk for serious illness.

  • You can quarantine in your home or at a public Isolation/Quarantine center. Do not go to work, school, or public areas. If possible, also stay away from people in your household who are at high risk of serious COVID-19 illness.

I live with someone who tested positive for COVID-19, what should I do?

  • For 10 days after your household member's COVID-19 symptoms started, avoid spending time in the same room and wash hands frequently. If you are in the same room, make it brief, maintain distance, and make sure that you both wear a mask.

  • Seek testing. If you test positive, follow the instructions on kingcounty.gov/nextsteps.

  • Monitor for symptoms. If you develop symptoms, separate yourself from others (isolate) and get tested right away.

  • This guidance also applies if multiple members of a household become infected during the same time period or outbreak.

  • If you are NOT up-to-date on your vaccinations and booster: Stay home without visitors (quarantine) for 5 days and seek testing on day 5. It's very important to test on Day 5 if possible. If you test positive while you are quarantining, you will need to start a new isolation period. If you do not have symptoms or test negative, after five days you can leave your home but must continue to wear a high-quality, well-fitting mask around others for five more days.

  • If you are up-to date with vaccinations and boosters: You do not need to quarantine. Wear a high quality, well-fitting mask for 10 days and test on day 5, if possible.


For healthcare professionals If you are a healthcare professional who thinks or knows you had COVID-19, you should notify your employer and follow the same recommendations listed above for when you can resume being around others outside the workplace. When you can return to work depends on different factors and situations—ask your employer for guidance. For information on when you can return to work, see: Criteria for Return to Work for Healthcare Personnel with SARS-CoV-2 Infection (CDC Interim Guidance).
