Releasing COVID-19 Cases from Isolation and Quarantine

English

Cases

Must be isolated for a minimum of 10 days after symptom onset (or specimen collection date if asymptomatic) and can be released when the following criteria are met:

  • Case is afebrile (without fever-reducing medication) for at least 24 hours and with improvement of COVID-19 symptoms.

OR

  • Case Has 2 Negative COVID-19 PCR tests in a row, with specimens collected and testing done at least 24 hours apart

A test-based strategy is no longer recommended in the majority of cases. Consult with infectious disease physician.

*A limited number of persons with severe illness or who are severely immunosuppressed may produce replication-competent virus beyond 10 days; this may warrant extending duration of isolation and precautions for up to 20 days after symptom onset or first positive test (if no symptoms). Consult with the infectious disease physician.

Close Contacts

Must be quarantined for 14 days after the last/most recent contact with the case when the case was infectious.

If a close contact develops symptoms, they should follow isolation rules for cases.

Contact Scenario Quarantine Period
Has close contact with someone who has COVID-19 and will not have further close contact 14 days from the date of last close contact
Has close contact with someone who has COVID-19 and lives with the case but can avoid further close contact 14 days from when the person with COVID-19 began home isolation away from other members of the household
Is under quarantine and had additional close contact with someone else who has COVID-19 Restart quarantine from the last day close contact occurred with anyone who has COVID19. Any time a new household member gets sick with COVID-19 and close contact occurs, quarantine will need to be restarted
Lives with someone who has COVID19 and cannot avoid continued close contact (e.g., shared kitchen/bathroom) Quarantine for 14 days after the person who has COVID-19 meets the criteria to end home isolation (see Cases information).
Was previously diagnosed with COVID-19 but did not undergo SARSCoV-2 testing and is now a close contact to a confirmed COVID-19 case Quarantine for 14 days from the date of last close contact to the COVID-19 case. Antibody testing results are not considered when determining quarantine status.

For COVID-19, a close contact is defined as being within 6 feet of an infected person for a cumulative total of 15 minutes or more over a 24-hour period starting from 2 days before illness onset (or, for asymptomatic patients, 2 days prior to test specimen collection) until the time the case is isolated.
