The incidence of COVID-19 in Japan has declined after the delta strain of the virus self-destructed. This version was made by a professor at the National Institute of Genetics Ituro Inoue in a conversation with the Japan Times.

He suggested that this subspecies disappeared due to constant mutations, which "broke" the delta strain of the coronavirus.

In addition, the incidence in Japan may have decreased due to high vaccination rates and adherence to measures to protect against infection.

The country broke records for daily morbidity for three months: the number of cases reached 26 thousand. To date, this figure barely reaches 200 cases.
