COVID-19 cluster at a Japanese hotel where dozens of Brazilian Olympic team members are staying raised new concerns about infections at the Tokyo Games, as the host city recorded its highest number of new cases for six months.
Just over a week before the opening ceremony, the spreading infections highlight the risks of staging the world's biggest sports event during a pandemic even without spectators in sports venues.
Seven staff at the hotel in Hamamatsu city, southwest of Tokyo, had tested positive for the coronavirus, a city official said.
But a 31-strong Brazilian Olympic delegation, which includes judo athletes, are in a "bubble" in the hotel and separated from other guests and have not been infected.
