CDC issued a press release and updated guidance clarifying the intent of updates first made to its isolation guidance on August 3. The guidance indicated that people can continue to test positive for up to 3 months after diagnosis and may not be infectious to others. In its clarification, CMS indicated that its August 3 guidance does not imply that a person is immune to re-infection with COVID-19 in the 3 months following infection and, at this time, it is not known whether someone can be re-infected with COVID-19. Rather, the latest data suggests that retesting someone in the three months following initial infection is not necessary unless that person is exhibiting symptoms of COVID-19 and the symptoms cannot be associated with another illness. Individuals who test positive for COVID-19 should be isolated for at least 10 days after symptom onset and until 24 hours after their fever subsides without use of fever-reducing medications
