Unlike the type A, which caused the group infection in the early stages of the corona19 spread or the Shinchonji Church in Daegu, health officials said that the virus was detected among the confirmed members of the Itaewon club.

Reporter Nam Joo-hyun analyzed how this type C virus, which is a pandemic in Europe and the United States and has a high propagation power, will affect the future of quarantine.


Type C, which is popular in Europe and the United States, entered Korea relatively later than Type A and Type B.

However, it is closely related to the recent collective infection.

The virus was caused by type C in the epidemic of clubs in Yecheon, Gyeongbuk, where 41 patients were diagnosed for the first time on the 9th of last month, and the Itaewon club, which recently had more than 200 diagnoses in the metropolitan area.

This trend is similar in other countries.

After the introduction of the C type, the C type overwhelmed the A and B in almost all countries, including Europe, the Americas, Japan, Taiwan, and Australia.

Since the spread of type C is faster than other genotypes, neglecting quarantine means that there is a greater risk of spreading type C in Korea.

Existing vaccine development strategies should also be devised broadly.

Health authorities have said there are no genetic mutations that affect the effectiveness of vaccines, but there are many opinions among experts that they should look closely to see if they can be applied to both types B and C, as the vaccine's antibody effect has not been accurately identified.
