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

Updated October 10, 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 until no fever for 24-hours (48-hours if you have nausea, vomiting, and/or diarrhea) and your symptoms have been improving for over 24 hours. 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.  You may return to campus once you have completed the isolation period. To determine if you are required to isolate, please refer to: If you are symptomatic or tests positive for COVID-19. You do not need clearance from the EHS Occupational Health Team but you may contact them if you have questions ( 

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.
