Isolation If you test positive for COVID-19, stay home for at least 5 days and isolate from others in your home. Wear a mask through day 10. You should also isolate if you are sick and suspect that you have COVID-19 but do not yet have test results. If you have questions contact UAH Health Services or your health care provider. When you have COVID-19, isolation is counted in days, as follows: If you had symptoms: Day 0 of isolation is the day of symptom onset, regardless of when you tested positive. Day 1 is the first full day after the day your symptoms started. If you did not have symptoms: Day 0 is the day you were tested (not the day you received your positive test result). Day 1 is the first full day following the day you were tested. If you develop symptoms within 10 days of when you were tested, the clock restarts at day 0 on the day of symptom onset. Quarantine Regardless of vaccination status, CDC is now recommending that instead of quarantining if you were exposed to COVID-19, you wear a high-quality mask for 10 days and get tested on day 6.
