While more fully vaccinated people are venturing out after a sharp decline during the Bon holidays, outings by the unvaccinated or those who have only received one shot have plummeted to around the lowest levels observed during the first state of emergency last year, Nishida said. The number of unvaccinated people who spent time late at night in Tokyo’s busiest entertainment areas has plunged since the Bon holidays in mid-August, he said, contributing to the overall decline. That’s down from around 1.7 in late July.īut the decline in the number of people going out at night does not fully account for the virus’s low reproduction number, Nishida said, adding that COVID-19 vaccination data also needs to be taken into account, and that’s where restraint among unvaccinated individuals has played a key role. The coronavirus’s reproduction number was only 0.66 over the past week, meaning on average each infected individual would infect 0.66 person. The daily number of COVID-19 cases in Tokyo fell to a three-month low of 235 on Friday from a high of more than 5,700 on Aug. “The (thorough) cooperation of Tokyoites is thought to be behind a sharp decline in infection numbers during that time.” “As a result, the number of those at high risk of infection who go out late at night has fallen to levels equivalent to the lowest level during the first state of emergency last year, and that status has been maintained for at least five weeks,” he told the metropolitan government’s weekly monitoring meeting on Friday.
18, down 23.1% from the final week before the current state of emergency was issued in the capital on July 12, the data showed. There were a little more than 1 million people spending time in those entertainment districts from 6 p.m. The Kabukicho entertainment district in Tokyo on June 28 | KYODO New infection numbers have fallen sharply over the past several weeks, as the majority of residents, including younger people, continue to refrain from dining out in groups, he added. The analysis showed that the number of people who went out at night in those potential hot spots has stayed low even over a pair of national holidays this week, while the movements of people in the daytime have been falling for three straight weeks, said Atsushi Nishida, the director of the institute’s Research Center for Social Science & Medicine Sciences. To find similar patterns in the capital, the Tokyo Metropolitan Institute of Medical Science analyzed GPS data to track the movements of people in seven major entertainment areas of Tokyo, including the red-light Kabukicho district, the famous Shibuya Center Street shopping arcade and Roppongi. Globally, such has proven to be a reliable indicator that corresponds closely with new COVID-19 infection figures and the virus’s basic reproduction number, which measures the pathogen’s transmissibility. In the Chicago metropolitan area, for example, 10% of public places, such as restaurants that serve alcohol and hotels, accounted for 85% of the predicted infections, according to the study that has been published in the science and technology journal Nature. The study led by a Stanford University team and other researchers analyzed mobile-phone GPS data and mapped the hourly movements of 98 million people to points of interests such as full-service restaurants and religious establishments. study showed just a fraction of places account for the overwhelming majority of infections. The importance of avoiding such hot spots has been gaining traction since a U.S.
