Continuing to test positive after recovery from COVID-19 infection is common, with some people still testing positive on a PCR test for weeks or months after their initial infection. This is because the PCR test is detecting viral remains that are no longer living and unable to cause infection. This means you are no longer contagious. Therefore, it is not recommended that individuals without symptoms undergo PCR testing for at least 90 days after the initial COVID-19 infection. If the person develops new symptoms of COVID-19 within that 90-day period, consultation with a health care provider is recommended to help with the decision on whether to do further testing. Rapid antigen tests (RAT) are generally less sensitive to the virus than PCR tests and work better in symptomatic people.  The sensitivity of the test can be increased by doing a combined oral (mouth) and nasal (nose) swab. If a person tests positive using a rapid antigen test, they should follow the Province’s public health advice. By 10 days after developing symptoms or testing positive (20 days if immune compromised), there are very few people who have any remaining viable virus – which means they are no longer contagious.
