Novel coronavirus, which has spread in Japan since June, is a novel coronavirus with a new gene sequence. Studies have shown that the spread of Japanese epidemic in Japan since March this year was mainly caused by coronavirus with related gene sequences in Europe, which temporarily subsided in late May. Since mid-June, a novel coronavirus with a new gene sequence has appeared in Tokyo and spread all over the country. At present, a large number of confirmed Japanese patients are mostly infected with this novel coronavirus variant.

1. Epidemic situation in Japan:

Statistics show that there are 47,464 confirmed cases and 42 deaths 1042 cases in Japan. There were 429 new confirmed cases in Tokyo on the 8th, and the total number of confirmed cases was 15536. Osaka Prefecture/KOOC-0/78 cases, Aichi Prefecture/KOOC-0/77 cases, Fukuoka Prefecture/KOOC-0/50 cases, Kanagawa Prefecture/KOOC-0/28 cases. On that day, 39 newly confirmed cases were reported in 47 prefectures and counties in Japan; The U.S. military stationed in Okinawa reported 7 newly confirmed cases, ***3 10 confirmed cases.

2. Try to avoid declaring a state of emergency again:

Abe held a press conference in Nagasaki on the 9th. Regarding whether the government will declare a state of emergency, he said? Measures must be taken to avoid it, because it will have an impact on employment and daily life? . Abe also said that the Japanese economy was severely hit by the state of emergency in April. It is estimated that Japan's GDP fell by more than 20% in the second quarter, the biggest decline since the US subprime mortgage crisis. In order to better balance economic and social life, the government plans to amend relevant laws after the epidemic ends.

3. Are COVID-19 varieties more contagious?

The transformation of aspartic acid (strain D) into glycine (strain G) in spike protein in novel coronavirus is very important for the infectivity of pathogenic bacteria. This spike protein plays an important role in the life mechanism of virus. Betty, a computational biologist at Los Alamos National Laboratory and the first author of the new paper? Cherbell said that he and his colleagues studied the GD strains of these two diseases in various ways and reached this conclusion. First, they made a statistical analysis to show how this mutant virus, called strain G, surpassed its existing version of novel coronavirus strain D in several continents, thus gaining an advantage.
