The group infection of Corona 19, which started at the Itaewon Club in Yongsan-gu, Seoul, is spreading to those who have not been to the club.

As the 2nd and 3rd wave spread in earnest, among the new confirmers related to the Itaewon club, the number of cases of contact with infected persons is higher than the club visitors.

According to the Central Defense Countermeasures Headquarters (Bangbang), the pattern of new entrants related to the Itaewon Club is changing from club visitors to contacts.

In the early stages of the situation, there were more confirmed cases centered on the visitors of the club, but by the 0 o'clock count, the first confirmed cases appeared on the 7th.

Since the last 10th, the manuscript has been released as a club visitor and contact person for Itaewon clubs.

On the 10th, among the confirmers related to the Itaewon Club, there were 18 visitors and 6 contacts.

Since then, on the 11th, there were 20 visitors, 9 contacts, on the 12th, 11 visitors, and 10 contacts, and from the 13th, more people were infected without going to the club.

Of the 18 confirmed Itaewon club related announcements on the 13th, 8 visitors and 10 contacts.

The gap widened further yesterday with 5 visitors and 15 contacts.

Collective infections from Itaewon Club are spreading all over the country, centered on the workplaces and homes of the confirmed people who have been to the club.

In addition to places where people live in their daily lives, such as at work or at home, there are cases that appear to be 'third infection', spreading through places such as karaoke.

Suspected patient, Yongin 66, infected a colleague, and in Incheon, 9 middle and high school students and 5 adults, including academy students, fellow lecturers, extracurricular students, and guardians, were infected by an instructor at a club.

At a hospital in Yeongdeungpo, Seoul, another employee and inpatient were serially infected from an occupational therapist who visited the club.

Experts believe that this 'N-th order' case will continue to emerge.

This is because it is unlikely that people exposed to Corona19 at the Itaewon Club would return to their homes and workplaces and spread the virus.

In particular, it is a concern that most of the club visitors are in their 20s and 30s who are socially active.

It is estimated that the number of contacts is small because they have a lot of interactions with friends and colleagues and a wide range of activities.
