Updated Guidance for COVID-19 Isolation and Quarantine 

Adopted from guidance issued on January 4, 2022 from:

New York State Department of Health and Centers for Disease Control and Prevention

Isolation for the General Population 

Isolation keeps someone who is infected/positive with COVID-19 away from others.

  • Anyone who tests positive for COVID-19 regardless of vaccination status must isolate. Isolate for 5 days (where day 0 is the day symptoms started, or day you test positive if asymptomatic).
  • If you have remained symptom-free or if symptoms are resolving, you can end isolation after 5 days. (Loss of taste and smell may persist for weeks or months after recovery and should not delay the end of isolation).
  • If you continue to have a fever or your other symptoms have not improved after 5 days of isolation, you should continue to isolate for 10 days and consult your primary care physician. 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
  • You should continue to wear a well-fitting mask 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 moderately to severely immunocompromised, isolate for 10 days.
  • Individuals not able to wear mask should isolate for 10 days.

Quarantine for the General Population 

Quarantine keeps someone who was exposed to COVID-19 away from others.

  • If you have been in close contact with someone with COVID-19, quarantine as follows, where day 0 is the last date of exposure:
  • If not fully vaccinated* or fully vaccinated and eligible for a booster but not yet boosted, quarantine for 5 days and wear a well-fitting mask while around others for an additional 5 days.
  • If fully vaccinated and boosted* (with the booster at least 2 weeks before the first date of exposure) or fully vaccinated and not yet eligible for a booster, no quarantine is required.
  • If you have recovered from COVID-19 in the last 90 days, no quarantine is required.
  • You should wear a well-fitting mask around others for 10 days from the date of your exposure.
  • If possible, get tested at day 5. If you test positive, isolate according to the guidance above.
  • If symptoms appear, quarantine and seek testing. In this situation, quarantine would end when the test is negative. If testing is not done, isolate according to the guidance above.
