Covid cases found at Olympic hotel as IOC hails 'historic' Games

A coronavirus cluster at a Japanese hotel where dozens of Brazilian Olympic team members are staying has raised new concern about infections. Seven staff at the hotel in Hamamatsu city, southwest of Tokyo, had tested positive, 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.
