The latest guidance from the CDC recommends that people who test positive for COVID-19 should stay home and away from others (isolation) for at least five days after testing positive, as this time period is when you are most infectious.

CDC recommendations for ending isolation:

  • If you had mild or asymptomatic COVID-19 and are fever-free after 5 days, you can end isolation but should wear a high-quality mask through day 10. 
  • If you had moderate illness (shortness of breath or trouble breathing) or severe illness (you were hospitalized), or you are immunocompromised, you should isolate through day 10. 
  • If you ended isolation but your COVID-19 symptoms recur or worsen, you should restart your isolation from day 0.

In addition to isolating, you should notify people you have been in close contact with, which the CDC defines as someone who was less than six feet from you for at least 15 minutes. If you have had symptoms, you should notify all the people you had close contact with, starting from two days prior to the onset of symptoms up until you tested positive and began isolating. If you are asymptomatic, you should notify all of your close contacts within the two days leading up to your positive test.

If you are symptomatic, you should monitor your symptoms. The risk of severe illness from COVID-19 is elevated for some groups — including older adults, people with underlying medical conditions, immunocompromised people, and pregnant or recently pregnant women. If you are at an increased risk for severe illness or have worsening symptoms over time, you should consult a health provider. If you experience emergency warning symptoms – such as difficulty breathing or chest pain – you should seek medical care immediately.

Regardless of when you end isolation, you should wear a mask through day 10. You can shorten this if you have access to rapid antigen testing and test negative twice, 48 hours apart.
