Athletes to be tested for COVID-19 every 4 days at Tokyo Olympics
Athletes will be tested for COVID-19 at least once every four days during their stay in Tokyo at the pandemic-delayed Summer Olympic and Paralympic Games, according to a "playbook" released by organizers Tuesday.
Over the past week, Olympics organizers have released different playbooks for each group of key stakeholders that outline COVID-19 protocols and rules of conduct for before, during and after the Tokyo Games, which are slated to open July 23. The playbook released Tuesday, which is aimed at athletes and team officials, warns that individuals could be kicked out of their events if they break protocols.
In addition to regular testing at the Games, athletes and team officials must take a COVID-19 test approved by the Japanese government within 72 hours of the departure time of their flight to the country, show proof of that negative test upon arrival and be prepared to take another test at the airport. Athletes will be barred from competing at the Games if they test positive for COVID-19.
Athletes and team officials will only be permitted to leave the Olympic and Paralympic Village, or other designated accommodation, to carry out the activities detailed in their "14-day activity plan," according to the playbook. They are not allowed to visit gyms, tourist areas, shops, restaurants and bars, among other places.
The playbook also asks athletes and team officials to keep two meters away from others and avoid "unnecessary forms of physical contact such as hugs, high-fives and handshakes."
The 2020 Summer Olympics were supposed to kick off in the Japanese capital last year on July 24. But in late March, amid mounting calls to delay or cancel the upcoming Games, the International Olympic Committee and Japanese organizers announced that the event would be held a year later due to the pandemic. They have been outwardly staunch in their determination to go forward with the Games ever since, even as Japan -- and much of the world -- face a resurgence of COVD-19 infections.
