The COVID-19 situation at the Tokyo Olympics has been "within expectations," the CEO of the organizing committee said Sunday, insisting that there is no link between the Games and surging infections in the capital and beyond.

"We are conducting more than 30,000 tests every day, quickly isolating any positive cases and taking appropriate steps to prevent the virus from spreading," Toshiro Muto told a media briefing.

"Having gone into these Olympics promising a safe and secure Games for all participants, Tokyo residents and the Japanese people, I think we have been able to keep COVID-19 at a level within expectations so far."
