These are the isolation guidelines if you in fact have COVID-19
https://www.cdc.gov/coronavirus/2019-ncov/if-you-are-sick/isolation.html
When you can be around others (end home isolation) depends on different factors for different situations.
Find CDC’s recommendations for your situation below.
I think or know I had COVID-19, and I had symptoms
You can be with others after:
At least 10 days since symptoms first appeared and
At least 24 hours with no fever without fever-reducing medication and
Other symptoms of COVID-19 are improving
**Loss of taste and smell may persist for weeks or months after recovery and need not delay the end of isolation
If you had severe illness from COVID-19 (you were admitted to a hospital and needed oxygen), your healthcare provider may recommend that you stay in isolation for longer than 10 days after your symptoms first appeared (possibly up to 20 days) and you may need to finish your period of isolation at home.
I tested positive for COVID-19 but had no symptoms
If you continue to have no symptoms, you can be with others after:
10 days have passed since the date you had your positive test
If you develop symptoms after testing positive, follow the guidance above for “I think or know I had COVID, and I had symptoms.”
