As of Tuesday, a total of 277 people who recovered from COVID-19 have retested positive here, according to the Korea Centers for Disease Control and Prevention (KCDC).
The country's central clinical committee for emerging disease control said there was no live virus present in such cases, positively refuting theories like the virus being reactivated or reinfection.
They said that apparent reinfection cases came because fragments of the virus remained in their bodies and showed up in test kits.
