As of 20 o’clock on August 8, local time, Japan had 1565 newly confirmed Covid-19 cases that day, and there were 1500 new cases every day for two consecutive days. According to Japanese media reports, the latest study by the National Institute of Infectious Diseases in Japan found that Covid-19, which has spread in Japan since June, is a mutant Covid-like virus with a new genetic sequence.

According to this study, the spread of the epidemic in Japan since March this year was mainly caused by the new type of coronavirus with related gene sequences in Europe, but it temporarily subsided in late May. Starting in mid-June, a new coronavirus with a new gene sequence appeared in Tokyo and spread throughout the country.

Currently, a large number of confirmed patients in Japan are mostly infected with this new coronavirus after mutation.
