The South African corona 19 virus, recently reported in the UK, is also believed to be a mutant virus of the ‘group G’ family, which is the most prevalent in Korea and around the world. It appears to be easier to infiltrate and infect the body than the British GR variant. This is reporter Kim Jeong-hoe. According to data from GISAID, the International Virus Genetic Information Exchange Organization, the current Corona 19 relapse in South Africa is led by mutant viruses. The group G strain, especially the GH type mutation, is leading the epidemic. For this reason, the new corona 19 virus from South Africa confirmed in the UK is dominated by Group G. Group G is currently the most prevalent worldwide among coronavirus 19 types, of which GH and GR types are also prevalent in Korea. In South African mutant viruses, 9 of the existing viral protrusions have disappeared and 3 have changed shape. In all three, the sites that bind to cell receptors have changed. There was also a change in location, which was closer to the cell receptor compared to the British GR type mutation. In the South African mutant virus, a dendritic mutation ‘N501Y’ was also found in the British mutant virus. In laboratory studies, UK mutant viruses have been reported to be up to 70% stronger than conventional viruses. Z-Side found that the South African mutant virus increased binding to the cell receptor. The Guardian also quoted local health experts in South Africa, predicting that person-to-person transmission would be easier than that of the British mutant virus. However, these contents have not yet been confirmed at the investigation stage. Recently, the appearance of mutant viruses in group G has been reported one after another, but experts point out that it is not due to the characteristic of type G and that the mutation occurs according to environmental conditions while group G prevails in all the world. This is YTN Kim Jeong-hoe.
