An athlete with the Serbian Olympic team has tested positive for coronavirus after arriving in Japan, less than three weeks before the Games, a host city official said Sunday. 

The member of the five-strong rowing team was found to have contracted the virus after a test at Tokyo's Haneda airport upon arrival Saturday, according to an official of Nanto, a central Japanese city, where the team planned to train ahead of the Olympics. The athlete has been isolated, while the remaining four have been transferred to a separate facility near the airport, the official said.
