Another mutation has been reported in the UK, where the Corona 19 virus was discovered, which has recently mutated 70% more. It is believed that this time it happened in South Africa and moved to the UK. Fortunately, no mutant viruses were recently discovered in Korea. However, if the virus that leads the epidemic changes abroad, the national trend is also followed, so a detailed analysis is necessary.
According to BBC Broadcasting and Reuters News on the 23rd (local time), two people who recently visited South Africa and entered the UK were infected with this mutation. The South African government confirmed on the 18th that scientists confirmed the Corona 19 virus mutation. According to the British Daily Guardian, Dr. Richard Ressels, who leads the mutant COVID-19 research in South Africa, said: “The mutation may have been more contagious and slightly more resistant to vaccines. “
Both British and South African mutant viruses are known to have multiple mutations in their surface dendritic proteins, making it easier for human cells to penetrate than conventional viruses. However, it was analyzed that it was not a mutation that caused serious disease or required other treatment. These mutations have yet to be discovered in Korea. Lee Sang-won, director of epidemiological research and analysis at Defense Countermeasures Headquarters, said in a briefing on the 24th: “We are confirming viruses collected at home and abroad through a full genome analysis, but no major mutations have been found. “
In Korea, there have been five mutations in groups S, V, GV, GR, and GH since the Corona 19 outbreak until now. In the early days of the outbreak of the Wuhan Koreans, group S was mainly found, and during the Daegu-Gyeongbuk epidemic, group V was the majority. The GH group has been leading the metropolitan area outbreak of the Itaewon group infection in Seoul in May until recently. The GR group was found mainly in Russian sailors. The viruses that lead the epidemic in each period are usually of the type that was prevalent abroad. The first S group was popular in Asia, including China. The GH · GR group led the Corona 19 epidemic in the United States and Europe, and at the same time, caused an epidemic in Korea.
So far, quarantine authorities have not seen any cases as a fatal mutation. The GH group estimated that the spreading power was 6 times greater on average, but the difference in mortality rate was not large. Professor Seol Dae-woo from the Department of Pharmacy at Chung-Ang University said: “Corona 19 is a structure where feces cannot be deposited, so there is no need to worry excessively about risk.” .
