Japanese government officials including Prime Minister Shinzo Abe had said the government would work hard to minimise any impact from the virus outbreak on the Games, which starts on July 24.
The death toll from the flu-like virus that originated in China’s central city of Wuhan has passed 490, as two U.S. airlines suspended flights to Hong Kong following the first fatality there and 10 cases were confirmed on a quarantined Japanese cruise ship.
Vaccines against the virus probably would not be ready by the start of the Tokyo Summer Olympics, a professor who looked at health risks ahead of the Games told Reuters, adding that he hoped there was enough time to build defences.
Saburo Kawabuchi, head of the Athletes’ Village for the 2020 Olympics, said he hoped the games would proceed smoothly, free from the virus.
Separately, Japan Sports Agency has started examining the impact of the virus on preparations by athletes for the Olympic and Paralympic Games, NHK, Japan’s national broadcasting organisation reported.
Several qualifying events including badminton and boxing have been postponed due to the virus.
