At a monitoring meeting on the 4th, the Tokyo Metropolitan Government announced that it had confirmed one virus suspected of being a new mutation that had never been confirmed in Japan, except for quarantine at the airport.
According to the city, what was confirmed was a virus that was suspected to have a mutation in "L452R" and a characteristic that some "spike protein" was deficient.
Except for quarantine at the airport, it has never been confirmed in Japan.
As a result of analysis by the Tokyo Metropolitan Institute of Health and Safety, a sample of a man in his 50s who returned from the North African region in mid-May was confirmed.
There are no close contacts with men, which means that they have already completed their medical treatment.
According to the capital, this virus has already been confirmed in 34 countries such as Germany, the United States, and the United Kingdom, but the actual situation is unknown, and the capital will proceed with further genome analysis in cooperation with the country.
In addition, at the monitoring meeting, it was reported that infection with a virus with a mutation of "L452R" found in India was confirmed in 28 people in Tokyo so far.
In addition, the positive rate of the virus with the "N501Y" mutation increased by more than 1 point from the previous week to about 83%, and experts analyze that it "became the main cause of infection".
