A total of 51 patients in South Korea were re-diagnosed with COVID-19 after recovering from the respiratory disease, according to a report that quoted Seoul officials.
Experts were dispatched to the COVID-19 hotspots of Daegu and North Gyeongsang province, where many of these cases were reported, said public broadcaster KBS.
Blood tests and other measures will examine whether the cases were reinfection or reactivation of the virus, the report quoted Director of the Korea Centers for Disease Control and Prevention (KCDC) Jeong Eun-kyeong as having said.
China and Japan earlier reported suspected cases of COVID-19 re-infection.
Experts say there are several ways discharged patients could fall ill with the virus again, Reuters reported. Convalescing patients might not build up enough antibodies to develop immunity to SARS-CoV-2, and are being infected again. The virus also could be “biphasic,” meaning it lies dormant before creating new symptoms.
Other experts have also raised the possibility of “antibody-dependent enhancement,” which means exposure to viruses might make patients more at risk of further infections and worse symptoms.
