What is the "closed-loop bubble" in epidemic prevention and control?

"Closed-loop bubble" is an epidemic prevention and control model, which means an isolated closed-loop management area.

This term was first proposed in the twenty measures to optimize epidemic prevention and control. On November 11, the "Notice on Further Optimizing the Prevention and Control Measures for the New Coronavirus Epidemic and Doing a Scientific and Accurate Prevention and Control Work" was released. Article 8 mentioned the "closed-loop bubble", which is for important business personnel and sports groups entering the country. etc., "point-to-point" transfer to the isolation-free closed-loop management area ("closed-loop bubble") to carry out business, training, competition and other activities. During this period, they are assigned code management and cannot leave the management area.

According to this regulation, the "closed-loop bubble" prevention and control model has three key points:

First, set up exclusive closed-loop management areas for specific people and activities.

Secondly, the "point-to-point" method is used when transporting these personnel.

Finally, people transferred to this area can move freely within this area, but cannot leave this area.

You should be able to understand this. In fact, my own understanding is to demarcate an area, and specific people can move freely within the area after being transferred.

In fact, the "closed-loop bubble" prevention and control model has taken shape. The 2022 Beijing Winter Olympics in February this year and the 2022 Chengdu World Table Tennis Team Championship from the end of September to early October. It can be said that they are all "closed-loop bubble" models.

For example, at the 2022 Beijing Winter Olympics, all entry personnel and related staff will be managed through a full process, fully closed, and point-to-point closed-loop. In the closed-loop area, special transportation will be provided for athletes and other personnel. You can move freely between the station and the venue, the venue and the venue and the competition area through transportation. Moreover, the closed-loop area is also equipped with daily and commercial services such as catering, Internet, and shopping.

Guangzhou proposed this model again a few days ago. On November 27, Guangzhou Haizhu District issued a relevant notice for the "East of Dongxiao Road-Changgang Road, Huangpu Chung-Chisha Chung-South China Expressway" Strengthened prevention and control measures will continue to be implemented in the area west of the main line - Guangzhou ring trunk line - Xinguang Expressway.

It is mentioned that the city’s government agencies, enterprises, institutions or institutions can apply to enter this area (except high-risk areas) in accordance with the "closed-loop bubble" prevention and control model in Article 20. Employees who have been negative for nucleic acid for 5 consecutive days, and have no symptoms of fever, sore throat, dry cough or other discomfort in the past 3 days, and whose health code is green, will be managed by "white list" and "collective code", and will be transferred to enterprises, institutions or institutions for management in a closed loop. closed loop.

You may not understand the "whitelist" and "collective code" here.

Regarding the "white list" mentioned in Guangzhou, at the epidemic prevention and control press conference on November 11, Zhang Yi, deputy director of the National Health Commission, mentioned that for those who recently left the Haizhu risk zone after activities Citizens are given a red code and are required to quarantine at home for three days. However, if citizens are involved in epidemic prevention and control, emergency response, etc. and need to go out, their units must apply to the prevention and control department to implement health management measures in accordance with relevant regulations and be included in the whitelist management. In fact, the "white list" is a measure set up for people who really need to go out.

There is also a "collective code", which is to register the industry and employees in relevant systems such as units, institutions, enterprises, etc. to form a personnel directory, as well as the personnel's health code, nucleic acid testing, vaccination, etc. The situation is updated in real time. For example, once a yellow code or red code appears, the prevention and control department can immediately identify risk personnel and take relevant measures.

As for epidemic prevention and control, I hope everyone will disinfect frequently, wear masks, ventilate more, and avoid gathering.
