This is the Gyeongsan Seorin Nursing Home where corona19 group infection occurred.

A 85-year-old woman confirmed here on the 2nd of last month was treated for hospital treatment and was judged to be cured on the 30th, but died yesterday (8th) and 9 days after the release of the quarantine.

This is a case of death after the first corona19 cure in Korea.

Health authorities weighed on the likelihood that the condition would have worsened when a patient with high blood pressure and a poor heart had corona19.

[Kim Shin-Woo / Director of Infectious Disease Management Team in Daegu City: The more severe a person is, the more likely he or she will remain in the lung fibrosis sequelae.

However, the possibility that Corona 19 was not cured cannot be ruled out because of the many sputum, diarrhea, and pneumonia findings after being judged.

Nationwide reaffirmation cases have steadily increased to 74.

The number is expected to increase further as Daegu City announced plans to test for coughing, shortness of breath, etc., of which 6.6% and 316 of the more than 4,700 local cures were reported.

Health authorities are looking into the relevance of antibodies in the body.

[Eun-Kyung Jung / Director of Disease Management Division: We study and investigate the parts of antibody formation and the meaning of antibody formation after infection more closely. We are working on building a system for antibody testing.]

If accurate research results on antibodies that suppress the virus appear to be possible, it would be possible to supplement the discharge criteria and select subjects for daily living.
