China News Service, Beijing, January 29 (Reporter Xing Chong) Recently, positive cases have been detected at Beijing Capital Airport and Olympic personnel in the closed loop. Brian McCloskey, chief expert of the medical expert group of the Beijing Winter Olympics Organizing Committee, said this on the 29th. He said that the epidemic prevention management in the closed loop is efficient, and a three-layer screening system is adopted. The first layer is before departure, the second layer is the arrival at the airport, and the third layer is entering the closed loop. Each layer will be tested, and it is possible to identify Positive.

"If you test positive before departure, you will be banned from participating. If you are in the incubation period, you may be detected on the second and third floors."

  At present, there is an epidemic in some areas of Beijing. McCloskey said that with the recent increase in the number of Olympic-related personnel arriving in China, the number of positive cases may also increase accordingly, but under strict closed-loop management, cross-spreading of epidemics inside and outside the ring will not be caused.

  Huang Chun, deputy director of the Epidemic Prevention and Control Office of the Beijing Winter Olympics Organizing Committee, said that the occurrence of positive cases in the Winter Olympics against the backdrop of the epidemic is a high-probability event, but under strict closed-loop management, frequent large-scale nucleic acid testing within the loop can be done immediately Screening out infected cases to block transmission. As long as all parties abide by the closed-loop epidemic prevention policy, the epidemic situation at the city level will not penetrate into the closed loop, and the epidemic situation within the closed loop will not spread to the city level.
