中新网北京1月28日电(王昊) 2月4日，北京冬奥会将在国家体育场“鸟巢”拉开帷幕。作为新冠疫情在全球范围暴发后举办的首届冬奥会，防疫措施一直牵动着各方心弦。北京冬奥会，将会交出一份怎样的防疫答卷？
政策全面
去年12月，北京冬奥组委与国际奥委会、国际残奥委会共同发布了(第二版)《北京2022年冬奥会和冬残奥会防疫手册》(下称“防疫手册”)，为所有利益相关方参与北京冬奥会、冬残奥会制定了防疫准则。
这一版防疫手册在保持第一版基本框架内容不变的前提下，吸纳了各利益相关方的意见建议，结合测试赛中发现的问题，对赛前防疫政策、既往感染者审核、核酸检测流程、利益相关方目的地清单、无症状感染者隔离设施标准等具体措施及相关细节进行细化完善，使防疫手册更具操作性。

第二版防疫手册补充了一些相关的防疫措施，比如增加了中方人员防疫要求，增加了流调工作的关键信息内容、运动员的观赛政策。
此外，防疫手册还细化了防疫相关内容。如赛前密接运动员相关政策，阳性人员复检相关流程，增加了境外检测机构的相关工作流程。
同时，防疫手册进一步明确了疫苗豁免审核的工作流程和既往感染者的审核流程。包括各利益相关方都非常关心的航班预定相关流程等问题，在第二版防疫手册当中都进行了明确。对于住宿交通等具体的服务标准，也进行了细化和完善。

而核酸检测时间、具体采样方式、各利益相关方可前往的目的地清单，都列入了第二版防疫手册之中。
With the release of the second edition of the epidemic prevention manual, the epidemic prevention policy of the Beijing Winter Olympics has been further refined and optimized, and a comprehensive epidemic prevention policy has become the most important guarantee for the epidemic prevention work of the Beijing Winter Olympics.
means innovation
In addition to the comprehensive epidemic prevention policy, the application of some scientific and technological means in the promotion of specific epidemic prevention work has also greatly improved the safety factor of the event.
After layers of selection, the bioaerosol new coronavirus nucleic acid detection system was identified as one of the "Science and Technology Winter Olympics" projects.
During the game, it is expected that aerosol collectors will be arranged in multiple venues to provide aerosol new coronavirus detection guarantee.

There will also be more than 100 "smart epidemic prevention personnel" on duty in major venues and Winter Olympic Villages. Participants do not need to take off their masks, and they can realize identification, intelligent temperature measurement and other inspection links within one second, maximizing the efficiency of information verification. , to increase traffic speed.
Previously, in the "Meet in Beijing" series of testing activities, some scientific and technological means of epidemic prevention have been applied.
There is a hand disinfection induction device at the entrance of the venue, and it also broadcasts "Please disinfect your hands and do personal protection" in both Chinese and English.
The staff wears an epidemic prevention card with a health pass code on their chest. They can swipe the code to view information at a specific location, and connect to the background big data platform. Through nucleic acid detection, health monitoring, real-time body temperature and other data, the gathering of people and related conditions are monitored. hint.

emergency complete
During the Beijing Winter Olympics, a large number of foreign athletes and their entourage will enter the closed loop of the Winter Olympics.
Given that the epidemic situation abroad is still severe, the Winter Olympics Organizing Committee has also prepared an emergency plan for positive cases of the new crown.
Take the National Snowmobile Center as an example: in November last year, the "Meet in Beijing" 2021/2022 International Snowmobile Federation World Cup was held at the National Snowmobile Center.
According to the epidemic prevention plan, all athletes implement closed-loop management. Their lives are two points and one line in hotels and venues, and they do not have contact with the outside world.
This arrangement is to ensure that even if there are positive cases of the new crown, there will be no impact on the outside world.

In the closed loop, according to regulations, once an athlete has a positive nucleic acid test result, an emergency plan must be activated quickly, and all established plans must be adjusted immediately.
Liu Jianhui, deputy director of venue services at the National Snowmobile Center, once introduced: "For example, when you arrive at the hotel, everyone knows that there is an infected person, who is his close contact, how to train in groups, how to ride the car, and how to eat and drink. These scenarios may guide ( Epidemic prevention manuals) are all in it, but once they are strung together, it becomes very complicated."
In response to such pressure, the event has established a comprehensive information base, such as the daily bus schedule of all athletes, and the order of the athletes' departure.
If you get feedback from the results of the nucleic acid sampling point, and a certain athlete is positive, you can quickly lock his current position.
