It was found that 51 cases of corona19 were cured and released from quarantine and reconfirmed.

The quarantine authorities decided to send an epidemiological investigation team to the Daegu and Gyeongbuk areas where many of these cases occurred.

Jung Eun-kyung, head of the Central Defense Response Headquarters, said at a regular briefing held at the Osong Disease Control Center in Chungbuk on the 6th.

Specifically, seven cases of corona19 confirmed to be re-positive by the inspection conducted after the decontamination of the confirmed patients were reported at the Blue Sanitarium in Bonghwa-gun, Gyeongbuk.

In Daegu, 18 cases have been reconfirmed.

"The epidemiological team will go down to the field and conduct an epidemiological investigation on cases that have been confirmed as re-cultivation," said Jung.

He plans to check the infectivity by separating and culturing the virus through a sample test for re-confirmed persons, and conducting blood tests to check whether it is reinfected or reactivated.

He also explained that the factors affecting this process will be analyzed.

"We will reveal the exact results after a comprehensive inspection," said Chung. "We are now seeing it as reactivated rather than reinfected because it has been released from containment and confirmed again in a very short period of time."
