Employees who have tested positive for COVID-19 should be re-tested before returning to the workplace to determine if they are still contagious. The re-test should occur when they no longer have a fever (without the use of medicine) and other symptoms have improved.
If an employee is unable to get re-tested, they can discontinue home isolation when they have met all three of these criteria and consulted with a healthcare provider and local and state health departments:
No fever for at least 72 hours, without the use of medication.
Improved symptoms.
At least 7 days have passed since the first onset of symptoms.
