Tokyo Olympics organisers have reported three new cases of COVID-19 infection among athletes - up from one new case a day earlier - as the population of the athlete's village swells before the start of the pandemic-hit Games next week.
Organisers reported 10 new cases connected to the Olympics, including media, contractors and other personnel, down from 15 on Saturday.
An International Olympic Committee member from South Korea has tested positive for the coronavirus on landing in Tokyo. Ryu Seung-min, a former Olympic athlete, is vaccinated and passed two COVID tests before leaving South Korea, reflecting the infection risk even from vaccinated attendees.
"I am completely asymptomatic, which probably has to do with the fact that I am vaccinated," Ryu says.
"I apologise to the organising committee, our hosts here in Japan and the IOC for the inconvenience I have caused.
"My case is just another proof that the system put in place to protect all of us is effective."
Infection rates are climbing among the general population of the capital, topping 1000 new cases for four consecutive days. Polls show many Japanese oppose holding the Games with the influx of overseas visitors it entails.
