In the corona19 diagnostic test, there was a case in which 'negative' came out and then it was judged as 'positive' again, but the quarantine authorities stated that 'it is not a matter that will affect the quarantine system'.

"The real-time gene amplification (RT-PCR) -based corona19 diagnostic method itself is highly sensitive," said Joon-Wook Kwon, deputy general manager of the Central Defense Countermeasures Headquarters, on the 26th. "It is judged that there are cases in which it may come out positive or a very small amount of virus in the body may be positive."

"There is also the possibility that the virus (against a small amount in the patient) may be positive again due to insufficient antibody defenses in the immune system," he said.

Kwon said, "But overall, I think it is not a situation that is very unusual or highly reverberant in terms of prevention and countermeasures against Corona 19."

Recently, in Daegu, 50s who had undergone self-isolation after undergoing a negative judgment were diagnosed positively after six days and were hospitalized and then died.

A 20-year-old who lived in Yecheon was discharged after receiving negative treatment after receiving treatment as a confirmed patient, but after six days, a prophylactic examination was positive.

Even the 70s in Siheung were reconfirmed after being confirmed again.
