"Best tested community" Tokyo 2020 is unique, not only in the way that is a historic first to be postponed but it is held with the COVID-19 pandemic still rampant, especially with its variants. According to the organizers, since July 1, 436 Olympic and Paralympic-related personnel tested positive for COVID-19 as of Sunday. 42,500 arrival tests were conducted at a positivity rate of 0.08%, and 571,000 screening tests at a positivity rate of 0.02%. "I think it's fair to say that the Olympic community here in Tokyo has been the best-tested Community anywhere in the world during the last few weeks," said the International Olympic Committee (IOC) president Thomas Bach. 5. Digital engagement As no spectators were allowed in the vast majority of the venues, the IOC resorted to digital engagement to create an atmosphere that made athletes feel they were not alone. A cheer wall was established in the stadiums with more than 250 million videos coming from different corners of the world, supporting athletes from their National Olympic Committees and the Refugee Olympic Team. According to the IOC, Tokyo 2020 social posts have generated more than 4.7 billion engagements as of Friday, with the majority of them during games time. 6. Anti-doping Zero positive cases were discovered in the competitions, which means no athletes are disqualified for anti-doping violations in Tokyo. However, Georgia's national shot put record holder Benik Abramyan missed his qualifying event on Tuesday after being provisionally suspended from competition due to a positive result in an out-of-competition test on July 31. Brazilian Olympic volleyball player Tandara Caixeta was sent home before their final clash with the United States after she was suspended in a doping case prior to the Olympics. /IANS
