first four patients were classified by the quarantine authorities as suspected cases of Omicron mutation infection.

This is a teenage son living with a couple in their 40s who was confirmed after entering Nigeria on the 24th, and Mr. A, an acquaintance who drove the couple from the airport to their house.

One of the 45 passengers who came on the same plane as the couple was also confirmed, but the test result confirmed that it was a delta mutation.

However, as a result of SBS coverage, an additional related confirmed person who had never been in contact with the couple was reported.

There are three people in all, and they are the family and acquaintances of Mr. A, who drove the couple home.

They were confirmed to have tested positive the day after Mr. A was confirmed.

Cases that are not classified as close contacts of the couple are confirmed cases.

The first infected couple completed their basic vaccinations with the Moderna vaccine at the end of October, but their son, acquaintances, and three additional confirmed cases were all confirmed as unvaccinated.

It is said that they do not have any symptoms at present, but the city of Incheon said that they were admitted to a hospital in Incheon because it was judged that they needed isolation.

In the case of the first infected couple and acquaintance A, the whole genome is currently being analyzed, and the results are expected to come out as early as tonight.

Quarantine authorities believe that the possibility of the couple being infected with Omicron is considerable.

The remaining confirmed cases are also being investigated for infection with Omicron, and there is a possibility that additional infections may increase further as the contacts of the confirmed cases are being investigated extensively.
