But some people may remain infectious for longer and this is because typically with viruses, the higher the viral load (the more virus circulating in the body), the higher the risk of transmission through known transmission pathways. So the more severe the illness and the higher the viral load, the longer you continue to shed the virus and are infectious.

If someone with mild disease has been symptom-free for 3 days and they developed their first symptoms more than 10 days prior, they are no longer considered to be infectious.

DO I NEED A DOCUMENTED NEGATIVE RESULT TO RETURN TO WORK?
If a worker has been diagnosed with COVID-19 and isolated in accordance with the guidelines, an employer may only allow a worker to return to work on the following conditions:

• The worker has completed the mandatory 10 days of self-isolation;
  
• The worker may need to undergo a medical evaluation confirming fitness to work.
  
• The worker on returning to work then needs to wear a surgical mask for 21 days from the positive test result while at work and practices social distancing and good respiratory and hand hygiene.
