A mutated virus came out from an overseas confirmed person who entered Korea. These are three viruses that have not been reported to the World Health Organization.

Three cases of COVID-19 virus mutations flowed in two cases from Pakistan and one from Uzbekistan.


All three mutations are the same in the spike protein that causes the virus to stick to the cells in our body.

However, all of them have different locations and all three have different lines.

The three infected with the mutated virus were self-quarantined immediately after entering the country, and there was no domestic transmission.

All of them are viruses that are not in the WHO's COVID-19 virus genetic information database, and further research is needed as the prospects that the effect of the treatment or vaccine may be similar when there is a mutation in the spike protein.

[Eun Ki Lee/Director of High Risk Pathogen Analysis Division, Center for Disease Control and Prevention: (Corona 19) There is no effect on diagnosis, and it seems that we need a little more review and further analysis regarding pathogenic and infectious history.] The

results of systematic analysis of domestic viruses were also available.

G group, also called type C, was divided into three smaller groups as it became popular worldwide. In domestic outbreaks, GH was overwhelming with 73%, while among overseas inflows, GR group was the largest with 56%.

From the Itaewon club to the recent Hongcheon campsite epidemic, most of the viruses belong to the GH group since May, but it has been virtually confirmed that a GR virus was detected in Russian ship repairers and infected by Russian sailors.
