Tokyo, July 18 : As the opening of the Tokyo Olympic Games is approaching, all eyes are on how the Games will be safely and successfully held in the midst of the COVID-19 pandemic. For overseas Olympians, the efforts to keep them safe start at the Narita International Airport, Japan's major gateway, as they are kept inside a "bubble" from others before they leave for their next destination. When athletes enter Narita's arrival hall after several hours of health and immigration procedures, they are cordoned off from fans and media, who are required to wait at designated areas to keep a two-metre distance from the athletes, reports Xinhua. Arriving athletes are required to take COVID-19 tests at the airport. While they are allowed to pick up their luggage first, they then have to wait at designated holding rooms "guarded" by officers in protective gear until they return negative tests. Within the holding rooms, members of the delegations are kept at a two-metre distance. They have to use designated washrooms which only allow one person at a time and must be accompanied by staff en route, even when there's only a 10-metre distance between the holding rooms and the washrooms. A staff member surnamed Peng, who was responsible for guiding China's women's football team upon their arrival on Saturday, said it was the guides' job to keep the athletes within a bubble and separate from others. "Athletes are not allowed to get on the bus on their own, use washrooms other than the designated ones, or eat at restaurants. We have to keep an eye out," said Peng. Peng was especially vigilant against the media. "You have to keep a two-metre distance, so you have to use an extension rod for the interview," he said, "If there's anyone on the team who tests positive , the whole team will be disqualified." The staff is also mindful of fans. When Argentina's men's football team arrived, it was immediately surrounded by fans, which attracted police and drew the ire of the Argentina coaches. "For the players' safety, fans should stay calm and restrain themselves," said Peng. /IANS
