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

"Closed-loop bubble" belongs to an epidemic prevention and control mode, and its significance is to isolate the closed-loop management area.

this term was first put forward in the twenty measures to optimize epidemic prevention and control. On November 11th, the Notice on Further Optimizing the Prevention and Control Measures of COVID-19 Epidemic was issued, in which Article 8 mentioned the "closed-loop bubble". For important business personnel and sports groups entering the country, they were "peer-to-peer" transferred to the isolated closed-loop management zone ("closed-loop bubble") to carry out business, training, competitions and other activities, and they were not allowed to leave the management zone during the period.

According to this regulation, there are three main points of the "closed-loop bubble" prevention and control mode:

First, set up an exclusive closed-loop management area for specific personnel and activities.

Secondly, these people are transported in a "point-to-point" way.

finally, the people transferred to this area can move freely in this area, but they can't leave this area.

You should be able to understand this. In fact, my own understanding is to delimit an area where certain people can move freely after being transported.

In fact, the "closed-loop bubble" prevention and control mode is embryonic. The 222 Beijing Winter Olympic Games in February this year and the 222 Chengdu World Table Tennis Team Championship from the end of September to the beginning of October can all be said to be "closed-loop bubble" modes.

For example, in the 222 Beijing Winter Olympics, all entry personnel and related staff are managed in a full-process, fully enclosed and point-to-point closed-loop manner. In the closed-loop area, athletes and other personnel are equipped with special means of transportation, and athletes and other personnel can move freely between the resident and venues, venues and venues, and competition areas through means of transportation. Moreover, in the closed-loop area, it is also equipped with catering, internet, shopping and other life and business services.

A few days ago, Guangzhou put forward this model again. On November 27th, Haizhu District of Guangzhou issued a relevant notice to continue to implement intensified prevention and control measures in the area of "Dongxiao Road-east of Changgang Road, Huangpu Yong-Chishayong-South China Expressway-Guangzhou Ring Road-west of Xinguang Expressway".

It is mentioned that enterprises or institutions in the city can apply for the employees in this area (except high-risk areas) who have been negative for five consecutive days and have no discomfort symptoms such as fever, sore throat and dry cough for nearly three days according to the "closed-loop bubble" prevention and control mode in Article 2, and the employees with green health codes are managed by "white list" and "collective code" and transported to enterprises or institutions in a closed loop.

You may not understand the "white list" and "collective code" here.

As for the "white list" mentioned in Guangzhou, it was the conference on epidemic prevention and control on November 11th. Zhang Yi, deputy director of the Health and Health Commission, mentioned that citizens who left after recent activities in Haizhu risk area were given a red code and were quarantined at home for three days. However, if citizens are people who need to go out to participate in epidemic prevention and control, emergency response, etc., their subordinate units shall apply to the prevention and control department, implement health management measures according to relevant regulations, and be included in the white list management. In fact, the "white list" is a measure set for people who really need to go out.

there is also a "collective code", which means that the information of the industry and employees of the unit, institution, enterprise and other related systems is registered and entered, and the personnel base book is formed, and the health code, nucleic acid detection and vaccination of the personnel are updated in real time. For example, once there is a yellow code or a red code, the prevention and control department can find the risk personnel at the first time and take relevant measures.

regarding the prevention and control of epidemic situation, I hope everyone can disinfect frequently, wear masks, have more ventilation and avoid gathering.

Today is another day to gain knowledge. Let's support those who find it useful.
