additional confirmed cases exceeded 2,000 again in six days. In particular, with more than 800 patients in Seoul alone, the number of patients in the metropolitan area was the highest ever.

<Reporter> A

group infection occurred at a high school in Gangdong-gu, Seoul.

After one student was first confirmed on the 10th, the number of patients increased to 14 in five days.

As large and small infections occurred in everyday life, such as schools, markets, workplaces, and restaurants, the number of confirmed cases in Seoul exceeded 800 for the first time.

Incheon also recorded the highest number of confirmed cases in a day, with 1,650 patients, the highest number ever in the metropolitan area.

Eight out of 10 confirmed cases in Korea are concentrated in the metropolitan area.

The quarantine authorities analyzed the effects of increased movement and allowed private gatherings of up to 6 people.

[Sohn Young-rae / Head of Social Strategy Team, Central Accident Remediation Headquarters: (in the metropolitan area) I am judging that the quarantine tension is somewhat lowered, and the epidemic is changing as the population fluidity increases… .] The

government repeatedly requested that the meeting time and frequency be reduced so that the spread of the metropolitan area does not spread across the country during the Chuseok holiday.

According to a study by the Korea Institute of Science and Technology, the risk of infection was 60% when they met for 12 hours, but the risk of infection was reduced to 35% after only 4 hours.

Shorter meeting times and frequent ventilation reduced the risk of infection by a third.

[Chansoo Kim / Dr. Korea Institute of Science and Technology (KIST): (When gathering for 4 hours) If you do not ventilate at all, the risk is about 50%, but if you ventilate once every 10 minutes, you can see that the risk of infection is reduced by 18%. There was.] I

asked you to wear a mask if ventilation inside the room is difficult.

The government said it would not be easy to maintain the current school attendance rate of about 80% if the spread of the virus increases after the Chuseok holiday.
