[단독]”The Japanese mutation is a comprehensive edition of Britain and South Africa…there are all key mutations”

The novel coronavirus infectious disease (Corona 19) mutant virus found in Japan was found to possess all of the key characteristics of the UK and South African variants. As Corona 19 prolongs, the virus is mutating in various forms.
Myung-don Oh (Professor of Infectious Internal Medicine, Seoul National University Hospital), chairman of the Central Clinical Committee of New Infectious Diseases, announced on the 11th that he found this fact by analyzing a mutant virus paper published by Japan on the 10th. On the 10th, the National Institute of Infectious Diseases in Japan published a summary paper entitled’On a new variant of the novel coronavirus found in returnees from Brazil.’ It is said that a variant was discovered on the 6th in the gene of the corona 19 virus of four Brazilian travelers who entered Japan.

“Japan has identified 12 mutations in the Spike protein receptor binding site, and the site does not match with the UK or South African variants, but it contains both the key mutant proteins of the British and South African variants.” The British variant has a propagation rate of at least 50% faster than the conventional one, which involves the N501Y mutation. The E484K mutation is the key to the South African mutant virus. Chairman Oh said, “This mutation in South Africa is known to reduce neutralizing antibodies (antibodies that neutralize the invading virus) by 10 times.” Japan’s National Institute of Infectious Diseases also said, “There is a concern that the immunity against the virus may weaken as the effect of the virus with the E484 mutation decreases.”
Chairman Oh said, “The combination of the British and South African mutant viruses may have turned into a Brazilian mutant, a South African mutated or another process may have resulted in a key mutation in the United Kingdom and South Africa,” he said. “The mutation process has not been confirmed.” said. The Japan Institute of Infectious Diseases said, “The results of this mutation analysis are limited to gene sequence information.” “The infectivity (transmission power) and pathogenicity (toxicity), the effect on the test method or vaccine, etc., are difficult to determine now, and further investigation is required.” Explained.
According to health authorities, the average number of arrivals in Brazil is about 20 per day. There is no direct flight, but 588 people departed from Brazil and entered the country via third countries in December last year, and 214 people from January 1-10. On the 10th, one arrival in Brazil was confirmed in airport quarantine and one was self-quarantined. This is the first time that airport quarantine has been confirmed since last December.
In a briefing on the 11th, Jung Eun-kyung, head of the Central Defense Countermeasures Headquarters, said, “Currently, different mutations have been identified in Japan than those in Britain and South Africa, and we are sharing information with the Institute of Infectious Diseases in Japan.” It will be released through a site that registers genetic information of ). We will also check for mutations and strengthen surveillance for those arriving in Brazil.”
Those arriving in Brazil will submit negative COVID-19 PCR results at the airport like other foreign travelers. Those with symptoms are inspected at the airport, and those without symptoms are inspected within three days of entry into the country at local governments or temporary living facilities, and before quarantine is lifted. However, one infection expert said, “Since September, people from Brazil and the United Kingdom must be traced back to analyze the gene of the virus.”
Meanwhile, as the WHO Corona 19 mutant virus follows, an expert advisory meeting will be held on the 12th to discuss this issue. Here, the latest information on virus mutations is exchanged and evaluated, and a response policy is planned.
