1. Positive COVID-19 Test
If you test positive for COVID-19 then the level of certainty that you have the virus is remarkably high. Unlike a false negative, a false positive is rare. After you have received a positive COVID-19 test, you should wait and retest to confirm that the active virus is no longer in your system.
Test before you go back to work, travel, visit an elderly friend/family member, or come into contact with the public. Only after you have obtained a negative COVID-19 test after testing positive for the virus should you stop self-quarantining.
Depending on your viral load, you might remain positive for COVID-19 for a month or more. This means that you could potentially expose people to the virus. You continue to actively shed live virus even if you no longer have any symptoms.
