Professor Hiroshi Nishiura (April 2020)
Hiroshi Nishiura, a professor at the University of Kyoto, and others have analyzed that the number of people infected with the new travel-related coronavirus has increased 6 to 7 times since the start of the government tourism support project “GoTo Travel” that started. in July of last year and the research team published it in an international medical journal.
In Japan, the infection spread again from July, becoming the “second wave” of the epidemic. Professor Nishiura noted that “the second wave had started to decline in mid-August, but GoTo’s initial business may have affected the spread of the infection” and will continue the analysis.
The team analyzed around 4,000 infected people in 24 prefectures, including Shizuoka, Okayama and Kumamoto, who developed the disease between May and August and had detailed information such as routes of infection and behavioral history. Of these, 817 had a history of traveling across prefectural borders or had contact with them. The number of infected people was compared between June 22 and July 21 before the start of “Go To Travel” and after the start.
As a result, the number of infected people per day increased about three times after the start. It was about 1.5 times more than the period immediately before July 15-19, including weekends. In addition, the number of people infected by tourism instead of business trips was up to 6.8 times, and compared to the previous period, it was 2-3 times. (Joint)
