Isolation is used to separate people infected with COVID-19 from those who are not infected.
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, stay in a specific “sick room” or area, and use a separate bathroom (if available).
To calculate your 10 full day isolation period, day 0 is your first day of symptoms. Day 1 is the first full day after your symptoms developed.
If you test positive for COVID-19 and never develop symptoms, 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 your positive test. If you develop symptoms after testing positive, your 10-day isolation period must start over. Day 0 is your first day of symptoms. Day 1 is the first full day after your symptoms developed.
What to do
- Monitor your symptoms. If you have an emergency warning sign (including trouble breathing), seek emergency medical care immediately.
- Stay in a separate room from other household members, if possible.
- Use a separate bathroom, if possible.
- Avoid contact with other members of the household and pets.
- Don’t share personal household items, like cups, towels, and utensils.
- Wear a mask when around other people if able.

When You Can be Around Others After You Had or Likely Had COVID-19
Most people do not require testing to decide when they can be around others; however, if your healthcare provider recommends testing, they will let you know when you can resume being around others based on your test results.
For Anyone Who Has Been Around a Person with COVID-19
Anyone who has had close contact with someone with COVID-19 should quarantine for 14 days after their last exposure to that person, except if they meet the following conditions:
Someone who has been fully vaccinated and shows no symptoms of COVID-19 does not need to quarantine. However, fully vaccinated close contacts should:
- Wear a mask indoors in public for 14 days following exposure or until a negative test result.
- Get tested 5-7 days after close contact with someone with suspected or confirmed COVID-19.
- Get tested and isolate immediately if experiencing COVID-19 symptoms.
- Self-tests are one of several options for testing for the virus that causes COVID-19 and may be more convenient than laboratory-based tests and point-of-care tests. Ask your healthcare provider or your local health department if you need help interpreting your test results.
Someone who tested positive for COVID-19 with a viral test within the previous 90 days and has subsequently recovered and remains without COVID-19 symptoms does not need to quarantine. However, close contacts with prior COVID-19 infection in the previous 90 days should:
- Wear a mask indoors in public for 14 days after exposure.
- Monitor for COVID-19 symptoms and isolate immediately if symptoms develop.
- Consult with a healthcare professional for testing recommendations if new symptoms develop.
I think or know I had COVID-19, and I had symptoms
You can be around others after:
- 10 days since symptoms first appeared and
- 24 hours with no fever without the use of fever-reducing medications and
- Other symptoms of COVID-19 are improving*
*Loss of taste and smell may persist for weeks or months after recovery and need not delay the end of isolation
Note that these recommendations do not apply to people with severe COVID-19 or with weakened immune systems (immunocompromised).
I tested positive for COVID-19 but had no symptoms
If you continue to have no symptoms, you can be with others after 10 days have passed since you had a positive viral test for COVID-19 (based on the date you were tested).
If you develop symptoms after testing positive, your 10-day isolation period must start over. Day 1 is your first day of symptoms. Follow the guidance above for “I think or know I had COVID-19, and I had symptoms.”
I was severely ill with COVID-19 or have a weakened immune system (immunocompromised) caused by a health condition or medication.
People who are severely ill with COVID-19 might need to stay home longer than 10 days and up to 20 days after symptoms first appeared. People with weakened immune systems may require testing to determine when they can be around others. Talk to your healthcare provider for more information. Your healthcare provider will let you know if you can resume being around other people based on the results of your testing.
People who are immunocompromised should be counseled about the potential for reduced immune responses to COVID-19 vaccines and the need to continue to follow current prevention measures (including wearing a 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 should also be encouraged to be vaccinated against COVID-19 to help protect these people.
For Healthcare Professionals
If you are a healthcare professional who thinks or knows you had COVID-19, you should 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. For information on when you can return to work, see the following:
