- People who are infected but asymptomatic or people with mild COVID-19 should isolate through at least day 5 (day 0 is the day symptoms appeared or the date the specimen was collected for the positive test for people who are asymptomatic). They should wear a mask through day 10. A test-based strategy may be used to remove a mask sooner.
- People with moderate or severe COVID-19 should isolate through at least day 10. Those with severe COVID-19 may remain infectious beyond 10 days and may need to extend isolation for up to 20 days.
- People who are moderately or severely immunocompromised should isolate through at least day 20. Use of serial testing and consultation with an infectious disease specialist is recommended in these patients prior to ending isolation.
