According to this recent article published by Medscape, some COVID-19 patients have tested positive for SARS-CoV-2 after they recover, raising the risk of further spread of the virus, say clinicians in Wuhan, China. To prevent a second wave of COVID-19 infections, they recommend a minimum period of 14-day clinical observation in medical “shelters” following recovery from COVID-19.

In a comment in The Lancet Infectious Diseases, they report on 651 patients from the Wuhan Pulmonary Hospital who were classified as recovered from COVID-19 and discharged into intermediary shelter hospitals or other health centers for 14-day clinical monitoring. “Because 35% of patients with a positive retest had one or more COVID-19-related symptoms, the usefulness of viral antibodies in COVID-19 clearance remains in question, and the potential for continued virus transmission after hospital discharge warrants additional investigation,” they write.
