The Tokyo Olympic organizing committee said Saturday the first positive case of COVID-19 has been detected in the Tokyo athletes' village with less than a week until the opening ceremony. The organizing committee did not identify the individual but said the infected person is a visitor from abroad involved in organizing the games, and not an athlete. The person did not share sleeping quarters with anyone, it said.

No specifics about the severity of the person's condition have been disclosed. The news comes as the number of Olympic-related arrivals to Tokyo grows, with the peak expected on Sunday. Muto informed the media of the first positive test taken at a regular screening at the village in the capital's Harumi waterfront district, but that he was unaware of the person's vaccination status.

The case was confirmed with a positive PCR test at an outpatient facility within the athletes' village. The case is one of 15 new positive results among games participants and workers reported on Saturday, the highest daily count since the committee started compiling figures on July 1. The overall tally does not include athletes at pre-Olympic training camps in Japan. Of the 15 infection cases, seven are contractors, six are Olympic staff members and two are members of the press. Eight traveled from abroad for the games and have been in Japan for fewer than 14 days, while seven are Japan residents. There have been a total of 45 COVID-19 infections announced by organizers since July 1. The village, with 21 residential buildings, 3,600 rooms and 18,000 beds, opened to athletes on Tuesday. International Olympic Committee President Thomas Bach, who arrived in Japan on July 8, told Japanese Prime Minister Yoshihide Suga that 85 percent of athletes and officials living in the Olympic village would be fully vaccinated against COVID-19. While in Japan, athletes are in principle restricted to the village and their training and competition venues as organizers try to enforce a "bubble" environment. They will also be subject to daily coronavirus screening. Bach, who visited the Olympic village on Thursday morning, was reported as promising there was "zero" risk of athletes transmitting the virus into the Japanese community or to other residents of the village. At a press conference on Saturday, he clarified the reporting over his comments, saying he was referring to zero risk of infection from three specific positive cases. Also on Saturday, Tokyo 2020 President Seiko Hashimoto told a press conference after the IOC Executive Board meeting at a Tokyo hotel that the IOC has praised Tokyo's preparations for the games. "We are doing everything possible to ensure that there is no COVID-19 outbreak," Hashimoto said. "I believe successfully pushing through to the end (of the games) is the legacy," she said. The Olympics run from July 23 to Aug. 8, and Tokyo's fourth coronavirus state of emergency is scheduled for July 12 to Aug. 22, lifting before the Paralympic Games open on Aug. 24.
