The BA.2.75 mutation, a so-called 'centaur' mutation, which is known to have stronger immune evasion characteristics than the existing mutation as a sub-mutation of the Corona 19 micron mutation, was first reported in Korea.
Summarizing the words of quarantine officials today (14th), the Incheon Institute of Health and Environment found a case suspected of having a BA.
The Korea Centers for Disease Control and Prevention plans to officially announce whether BA.2.75 is correct after performing a whole genome test on this sample.
The confirmed person with this sample is in their 60s living in Incheon, and is included in the general management group and is quarantined at home for 7 days like other patients.
A quarantine official said, "The infection is likely to come out tonight or tomorrow morning."
It is known that the confirmed patient of this sample has no overseas travel history.
If the BA.2.75 mutant infection is confirmed, it is likely that the virus has already spread in the community.
BA.2.75 was first discovered in India at the end of May and has spread rapidly last month, and was also found in about 10 countries, including the United States, Australia, Germany, United Kingdom, Japan, New Zealand, and Canada.
Due to its rapid spread and strong immune evasion properties, it is called 'Centaur', the half-human and half-beast of Greek mythology.
Compared to previous submutations, there are more mutations in the spike protein, which is known to make the virus more effectively bind cells and evade antibodies formed by vaccines or infections.
