COVID-19: I have completed the isolation period. When can I return and do I need to be tested to return to campus?

July 5, 2022

Generally, use of rapid antigen/molecular test result (negative) to end a self-isolation period early after an initial positive test is not recommended (e.g., use of rapid antigen test to obtain a negative result to end self-isolation period early after an initial positive test). 

Molecular testing (i.e. PCR) is no longer being recommended for all individuals in the community with symptoms compatible with COVID-19. If individuals with COVID-19 symptoms have access to rapid antigen tests, rapid antigen tests may be used to assess the likelihood that symptoms are related to COVID-19, otherwise individuals should isolate following the time-based clearance guidance. Rapid antigen test should only be used to determine when an individual needs to go into isolation, not for when isolation ends.

An individual who had COVID-19 will test positive for weeks after their symptoms have resolved and is most likely no longer contagious if symptoms resolving for over 24 hours. The end of isolation is determined by time (e.g. 5 days) and not by testing. You may return to campus once you have completed the isolation period. You do not need clearance from the EHS Occupational Health Team but you may contact them if you have questions ( 

After your isolation period has ended, you must continue to wear a well-fitted mask in all public settings for another five (5) days (or ten (10) days if you are immunocompromised).

Please also review the webpage for individuals who are symptomatic for more information.  We continue to monitor Public Health guidance for any changes and update UofT protocols accordingly.
