South Korea health authorities say that 51 people there who had recovered from COVID-19 have tested positive again, according to the Yonhap News Agency.
The Korea Centers for Disease Control and Prevention said the recovered patients retested positive after being released from quarantine. The director-general of the Korea CDC said that the positive retests were likely due to the virus being reactivated, as opposed to the people being reinfected.
A team has been sent to region where the people retested positive to conduct an epidemiological investigation into the cases, health authorities said.
There have been 10,331 total cases of the new coronavirus in South Korea, according to a dashboard created by Baltimore-based Johns Hopkins Medicine.
