I’ve been exposed to someone with COVID-19. Do I need to quarantine and for how long?

If you are not fully vaccinated and have been exposed to someone with COVID-19, you should quarantine yourself immediately for 10 days. Unvaccinated employees and students can leave quarantine after 10 days (including returning to work and to in-person class) following your most recent exposure, provided you do not develop symptoms of COVID-19. You must quarantine for 10 days even if you test negative for COVID-19 before that time. If you are required to complete weekly testing on campus, you should plan to do so while in quarantine, but limit your interactions with others, avoid shared and public transportation, and wear a mask.

If you are fully vaccinated (it has been two weeks since your final dose of the vaccine), you are not required to quarantine even if you have a close contact who is positive for COVID-19. You should get a COVID-19 test 3-5 days after a known exposure and at any point if you experience symptoms.

If you tested positive for COVID-19 within the previous 90 days, you should monitor for symptoms; you do not need to test or quarantine following a close contact. However, if you develop symptoms, you should isolate yourself and get tested.

If you develop symptoms of COVID-19, whether you are vaccinated or unvaccinated, you should get tested for COVID-19 and isolate immediately. If your test result is negative, you should consult a health care provider before returning to work or class.
