When to isolate: a quick reference guide

ISOLATION GUIDANCE

As of March 11, 2022.

Individuals who have symptoms of COVID-19 OR tested positive on a COVID-19 test (PCR or rapid) should self-isolate immediately. To see if you are eligible for a PCR test, click here.

The time of the self-isolation period depends on age, vaccination status, severity of infection, and immune status.

PopulationIsolation Period
• Fully vaccinated individuals
• Children under the age of 12
5 days after the date symptoms started or the date of COVID-19 testing (whichever is earlier)
• Individuals 12+ who are not fully vaccinated
• Immunocompromised individuals
• Hospitalized for COVID-19 related illness
• Residing in a highest risk setting (e.g. hospitals, congregate living facilities)
10 days after the date symptoms started or the date of COVID-19 testing (whichever is earlier)
• Severe illness (requiring ICU level of care)20 days after the date symptoms started or the date of COVID-19 testing (whichever is earlier)

If self-isolation is complete after 5 days, additional precautions are needed due to residual risk of ongoing infectiousness.

For a total of 10 days (or 20 days for immunocompromised individuals) after symptom onset (or date of specimen collection, whichever is earlier/applicable), individuals must:

  • Continue to wear a well-fitted mask in all public settings
    • Individuals should maintain masking as much as possible in public settings. Reasonable exceptions would include temporary removal for essential activities like eating (e.g., when eating in shared space at school/work while maintaining as much distancing from others as possible)
    • Participation in activities where masking can be maintained throughout may be resumed, but individuals should avoid activities where mask removal would be necessary (e.g., dining out)
    • Individuals who are exempt from masking (e.g., children under two years of age, etc.) may return to public settings without masking
  • Not visit anyone who is immunocompromised or at higher risk of illness (i.e., seniors)
  • Not visit or attend work in any highest risk settings.
