The Tokyo Olympics can be held this summer even if the capital is under a coronavirus state of emergency due to a spike in infections, a top official of the International Olympic Committee said Friday, amid persistent concerns over whether they can proceed safely during a global health crisis.

"The answer is absolutely yes," John Coates, an IOC vice president, told a virtual news conference when asked whether the Tokyo Games can be delivered under a state of emergency, citing advice on anti-virus measures from the World Health Organization and how Japan "successfully" conducted test events recently.

Upon the conclusion of a three-day remote meeting with the IOC, Seiko Hashimoto, president of the Tokyo organizing body, said as many as 230 doctors and 310 nurses will be needed per day during the games, adding that about 80% of the medical workers have been secured.
