COVID-19 PATIENTS ARE NOT INFECTIOUS 11 DAYS AFTER GETTING SICK, STUDY SUGGESTS.

A study out of Singapore suggests that COVID-19 patients are not infectious 11 days after getting sick. The researchers noted that a separate study out of Germany found "the degree of viral shedding was very high in the first week of symptoms," supporting their findings.

A separate study from the Korean CDC appears to suggest that patients who test positive for COVID-19 after having previously recovered are not capable of transmitting the infection.
