Corona 19 in Korea started with a group infection from colleges, academies, and hospitals, and is leading to'n-th infection'.

In particular, as the number of confirmed local outbreaks approached the level at the end of August, when the'second epidemic' centered on the metropolitan area was in full swing, the government has opened a plan to raise the social distancing stage, which is the 1.5 stage, to stage 2, and is reviewing various measures. .

According to the Central Defense Countermeasure Headquarters (Bang Dae-bon), following yesterday (the 21st), confirmed cases of group infections related to school, student meetings, and academy occurred one after another.

In the metropolitan area, 58 people were tested positive in a pile during the short-term appointment academy in Noryangjin, Dongjak-gu, Seoul, and the cumulative confirmed number increased to 69.

The confirmed cases are spread across the country, including Seoul, Incheon, Gwangju, Gyeonggi, Gangwon, Chungbuk, Chungnam, Jeonbuk, and Jeonnam, with 66 students from the institute, two from the institute, and one family member.

Sook-young Lim, head of situation general manager Bang Dae-bon, explained, "The tests were all completed until late last night for 603 confirmed patients, close contacts, and school students who are concerned about spreading, and 69 of them were confirmed."

Director Lim said, "The test takers who were confirmed were inevitably prevented from taking the test, and even those who were confirmed negative could take the test at a separate test center."

Bang Dae-bon analyzed that the academy was vulnerable to group infection because many students gathered in a narrow space and it was difficult to provide adequate ventilation.

As a result of an epidemiological investigation, it is known that this group infection was derived from a case involving family and acquaintances in Namdong-gu, Incheon.

Looking at the estimated route of infection, the first patient (indicator patient) in the case of a family and acquaintance in Namdong-gu, Incheon, attended a acquaintance meeting at a restaurant, and it was investigated that it was spread to Noryangjin Appointment Examination Academy through acquaintances who attended the meeting.

In the case of family and acquaintances in Namdong-gu, Incheon, 41 confirmed cases have occurred so far.
