The mutated new coronavirus has spread to 19 prefectures in Japan, and the proportion of mutated virus infection has increased in some areas

The proportion of mutated viruses in the tested samples has increased significantly, and the proportion has been close to half recently.
Japan’s Ministry of health, labor and welfare said on the 4th that up to now, the areas with highly infectious variant new coronavirus have been expanded to 19 prefectures. Experts believe that “compared with the current epidemic situation, the risk of accelerating the spread is increased”, which may lead to the “fourth round” epidemic situation, which will have a bad impact on lifting the emergency declaration and hosting the Olympic Games.
The Japanese government is stepping up surveillance of three mutated new coronaviruses found in the UK, South Africa and Brazil. Since the first case was reported in Japan on December 25 last year, as of March 4, 234 cases have been confirmed, including those found in Airport Quarantine. By region, Saitama county had 38 cases, Hyogo County 36 cases and Niigata County 29 cases.
Kobe City, Hyogo County, announced on the 1st that the samples of Kobe new coronavirus positive people were tested. From January 1 to February 18, 36 samples were confirmed to be infected with mutated new coronavirus. The proportion of mutated viruses in the tested samples has increased significantly, and the proportion has been close to half recently.
Kobe said that the results of genomic analysis of the mutated virus by the Municipal Environmental Health Research Institute showed that 31 samples were mutated viruses found in the UK. Although no mutated viruses were found in South Africa and Brazil, the other five samples had the same “e484k” mutation with the two viruses.
It is reported that the Japanese government has asked local health research institutes across the country to carry out mutation virus confirmation testing for about 5% ~ 10% of the positive samples, while Kobe City has tested about 60% of the positive samples.
