- If you have had close contact to someone with COVID-19, please follow current guidance on isolation and quarantine.Test immediately if you have symptoms of COVID-19 at any time.
- Test within 3-5 days after exposure if you have no symptoms*
*If you recovered from COVID-19 in the last 90 days and do not have new symptoms after a close contact, you do not need to test.
