Tokyo’s Covid-19 infections have surged to a six-month high with the Olympic host city logging 1,832 new cases just two days before the Games open, AP reported.

Tokyo is currently under its fourth state of emergency, which will last until Aug 22, covering the entire duration of the Olympics that start on Friday and end on Aug 8. Fans are banned from all venues in the Tokyo area, with limited audiences at few outlying sites.

“What we have worried about is now actually happening,” Japan Medical Association President Toshio Nakagawa said at a weekly news conference. “The surge in cases has been expected whether we have the Olympics or not, and we are afraid that there will be an explosive increase in cases regardless of the Olympics.”
