New corona infection continues underwater? Will it reappear after mid-June? August 7, 4:00
Although the infection with the new coronavirus is continuing to spread, in Japan, the infection with the virus, which once seemed to have converged in May, continues under the surface of the water, and it seems that it has reappeared since mid-June. As a result of detailed analysis of the viral genes conducted by the National Institute of Infectious Diseases.
The research institute said that, after the self-restraint of migration was alleviated, an invisible infection may have spread nationwide.
The National Institute of Infectious Diseases announced the results of a detailed analysis of the viral genes detected in infected people in Japan and how they spread.
According to this, the virus that has spread domestically since mid-March is a type called "European strain" that came from China from Wuhan through Europe, and in May the infection by this virus once stopped. I went to.
However, after mid-June, clusters of infected people = clusters occurred in various places, and when analyzing the virus, it was found that a part of the gene of the "European strain" virus, which was once invisible, was mutated It means that It is said that mutations that increase or decrease the pathogenicity have not been confirmed.
In the laboratory, infections by asymptomatic or mildly infected persons continued under the surface, and after mid-June, infections by viruses of the same strain re-emerged, and the self-restraint of migration was relieved. It is said that it may have spread all over the country without fitting.
