Duration of Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) infectivity: when is it safe to discontinue isolation?
This review examined the current evidence of when a Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) patient is no longer infectious and no longer needs to be in isolation. Most patients have persistently positive tests for weeks to months following clinical recovery; but this may not indicate their infectivity. SARS-CoV-2 appears to be most contagious around the time of symptom onset. Infectivity decreases to near-zero after about 10 days in mild-moderately ill patients and 15 days in severely-critically ill and immunocompromised patients. The longest interval associated with replication-competent virus found so far is 20 days from symptom onset.

The value of decreasing the duration of the infectious period of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection.
Researchers developed a computational model of the U.S. simulating the spread of SARS-CoV-2 and the potential clinical and economic impact of reducing the infectious period duration. They reported that their study quantifies the potential effects of reducing the SARS-CoV-2 infectious period duration.
