Tokyo organizers and the International Olympic Committee have repeatedly said they have no contingency plans for the July 24-Aug. 9 Summer Games since the WHO declared a global health emergency last month.

The U.N. agency's emergencies program director, Michael Ryan, said Tuesday the sporting event was "way too far" away to consider giving advice that would affect Tokyo's hosting of the Olympics.

"We are not there to make a decision for that," Ryan told The Associated Press on the sidelines of a news conference at WHO headquarters.

Geneva-based WHO has been in regular contact with the IOC in nearby Lausanne since the virus known as COVID-19 emerged in December.

"We don't give them judgments," Ryan said. "We assist them with their risk assessment. We will be working closely with them in the coming weeks and months."

The death toll in mainland China due to the virus rose to almost 1,900 on Tuesday, with more than 72,000 confirmed cases.

The outbreak has caused numerous sports events in China to be canceled, postponed, or moved, including qualifying events for the Tokyo Olympics.

Chinese athletes and teams have also been unable to travel for some competitions. China sent a team of more than 400 athletes at the 2016 Rio de Janeiro Olympics. It won 70 medals, including 26 gold, and placed third in the medals table.

Around 11,000 athletes and many more team coaches and officials from more than 200 national teams are expected in Japan for the Olympics.

Japan has experienced the most significant outbreak of the virus outside of China, on the cruise ship Diamond Princess docked in quarantine at Yokohama in Tokyo Bay.

During a 14-day isolation that ends Wednesday, 542 cases have been identified among more than 3,700 passengers and crew.
