The Tokyo 2020 Olympics will begin on Friday -- but concern is growing over the danger of Covid spreading, with 55 confirmed cases now linked to the Games, including officials and contractors.

The Japanese public, as well as many international observers, have voiced alarm over the Games going forward as Japan struggles to rein in its latest coronavirus outbreak.

The country saw a huge second wave in the spring, peaking in April and May with close to 6,000 new cases per day.

Cases began falling in June but have risen in recent weeks, sparking fears the arrival of teams from more than 200 countries could turn the Games into a global superspreader event.

As of Friday, more than 15,000 Olympic individuals had entered Japan, according to Thomas Bach, president of the International Olympic Committee (IOC).
