additional confirmers of the day, which once went down to 10 people, increased again as you can see now. However, if there were no infected people at the Itaewon Club as it is now, the team at the National Cancer Center, Kimran, said that there would have been one more confirmed patient at the end of this month. That doesn't help blame the detainees or drive the people who went there. It is of the utmost importance for now to be tested quickly and to follow the instructions of the health authorities.

0.58, I'll explain this number first.

The number of infection reproduction is a measure of how many corona19 patients carry the disease over a certain period of time.

If the number of reproduction is 1, it means that 1 person spreads to 1 person. If this is less than 1, the number of patients decreases, and when it exceeds 1, the number of patients increases.

This number fell to 0.58 by the end of last month, just before the Itaewon club group infection.

However, the average from the past 2 days of the club infection to yesterday (12th) was 2.58.

With this trend, at the end of this month, there may be over 400 confirmed people a day.

Of course, given our quarantine abilities, it is very likely that this level will not get worse.

But there is one important variable.

It is the case that the number of people who do not receive tests on time increases.

One out of every 10 subjects is 30% more likely to have passed two weeks after being untested.

If 3 out of 10 don't get it, the patient can double up.

It means that checking and quarantining in time is the most important thing for now.

According to the National Cancer Center's team of professor Kim, Kim, it is predicted that it will be around mid-June, at least as soon as a month before the new confirmed patients return to the level at the end of last month when there were less than 10.
