However, among the 92 active participants in the study (all were fully vaccinated), 17 percent tested positive after five days, so the second component of the CDC and the BU, consistent guidelines of wearing masks for an additional five days remain vital. If you test positive for COVID-19 and never have symptoms, isolate for at least 5 days. Day 0 is the day of your positive viral test (based on the date you were tested) and Day 1 is the first full day after the sample was collected for your positive test. You can leave isolation after 5 full days.
More broadly, people are likely to test positive for a rapid COVID-19 test at home for about six to 10 days, said today Dr. Stephen Kissler, a postdoctoral fellow at the Harvard T H. Chan School of Public Health, in the department of immunology and infectious diseases. If you test positive for COVID-19 after being quarantined and no longer showing symptoms, do you still have to stay in isolation?.
