Fortunately, at the Samsung Seoul Hospital where 4 nurses were confirmed, there were no additional confirmed patients today (20th). However, the results of more than 500 of the contacts have not been released. I am a reporter covering Samsung Seoul Hospital.

Reporter Kim Hyeong-rae, are all the contacts who had the results of the test once negative?

<Reporter>

Yes, as the epidemiological investigation progressed, the number of contacts of four confirmed nurses exceeded 1,200, of which 641 were negative.

However, it is still possible that more than 550 people will be waiting for the results of the examination, and additional confirmers will emerge.

Apart from this, there was one additional confirmed patient outside the hospital, and a nurse in her 20s in Seosan, Chungnam, the friend of the first confirmed nurse at Samsung Seoul Hospital, was confirmed as confirmed today asymptomatic.

The two were found to have met from the night of the 9th to the next day, about a week before the symptoms appeared at a nurse in Samsung Hospital.

It is not yet known which of the two was infected first, or whether there was a common source of infection.

Didn't the path of infection of the nurses be known exactly?

<Reporter>

Yes, the route is still in the middle of now.

Health authorities are conducting epidemiological investigations on the possibility that one of the nurses was first infected from the outside and then spread the virus in the public space.

The authorities say that there is no link to the Itaewon Club infection.

<Anchor> The

hospital closed the operating room yesterday and stopped new hospitalization in the main building, was there any other action?

<Reporter>

Yes, Seoul Mayor Park Won-soon said that he believes it is currently under control and does not take additional measures into consideration, such as isolating the entire hospital.

An important variable will be whether or not there are additional confirmers during the incubation period.
