In order to further improve the scientific and accuracy of epidemic prevention and control, the joint prevention and control mechanism of the State Council recently released the "New Coronatte Pneumonia Pneumonia Prevention Plan (Ninth Edition)". What is the basis for the ninth edition of the prevention and control plan? What are the targeted adjustments? How to really implement it? Authoritative experts of the State Council's joint defense and control mechanism interpret.

Adjust the situation based on science basis

The ninth edition of the prevention and control plan comprehensively implements the general strategy of "external prevention input, internal prevention and rebound" and the general policy of "dynamic clearing zero". For the characteristics of Omikon's mutation, the isolation of the epidemic monitoring and risk personnel due to the situation is due to the situation. Adjustment of management and mid -to -high risk regions have been adjusted.

Lei Zhenglong, deputy director and first -level inspector Lei Zhenglong, explained the basis of the ninth edition of the regulation of prevention and control programs from the changes in the situation of the epidemic situation, the characteristics of virus mutation, and the preliminary pilot research.

He said that at present, the epidemic of new crown pneumonia has continued to be popular worldwide, and the frequency of local epidemic in the country has increased significantly since this year. The study reminds that Omikon's mutant plant has a short latent period, stronger communication ability, and faster dissemination, and has stronger immune escape ability, bringing new challenges to the prevention and control of the epidemic.

"From April to May of the State Council's joint prevention and control mechanism, from April to May this year, 7 cities including Dalian, Suzhou, Ningbo, Xiamen, Qingdao, Guangzhou, and Chengdu carried out the pilot research work of the new crown epidemic prevention and control measures and obtained a lot of scientific basis." Lei Zhenglong said that combined with the practice of preventing and controlling control in various places, especially in Shanghai, Jilin and other places, it was amended to the prevention and control plan with reference to the Guide of the World Health Organization in the first half of the year.

"The ninth edition of the prevention and control scheme is the optimization of prevention and control work. It is by no means relaxation and control. The goal is to be more scientific and accurate." Said the relevant person in charge of the National Committee of the National Health and Health Commission.

Focus on three aspects to revise and improve accuracy and normality

Relevant persons in charge of the National Health and Health Commission's CDC reminded that the ninth edition of the prevention and control plan is by no means relaxing and controlling, but to require more standardized and accurate, control the key risks that should be controlled, and implement the measures that should be implemented in place. Compared with the eighth edition prevention and control plan, the ninth version of the prevention and control scheme is mainly revised in three aspects:

First, for the isolation management period and method of the risk personnel, the ninth edition of the prevention and control plan proposes that the time and control time of close contact and entry personnel is adjusted from "14 days of centralized isolation medical observation+7 Heavenly Home Health Monitoring" to "7 days Concentrated isolation medical observation+3 Heavenly House Health Monitoring ", and the discharge of double inspections before the centralized isolation medical observation; adjust the densely connected tube control measures from the" 7 -day centralized isolation medical observation "to" 7 Heavenly House Observation Medicine Observation " Essence

In this regard, Wang Liping, a researcher at the Defense Office of the China Centers for Disease Control and Prevention, said that the study found that the average incubation period of Omikon's mutant strain was shortened, mostly 2 to 4 days; most of them could be detected within 7 days. Such adjustments do not mean the "looseness" of prevention and control measures, but to further optimize prevention and control measures based on the popular characteristics of Omiko's mutant strains. It will not increase the risk of epidemic dissemination and it is a reflection of precision prevention and control.

The second is to set standards around the sealing control area and mid -to -high risk areas. The ninth edition of the prevention and control scheme of the two types of risk areas delineates standards and prevention and control measures. Determine and control schemes.

"The high -risk zone adopts the control measures of 'not leaving the house, on -site service'; the central risk zone adopts the control measures of 'people who do not get out of the region, the peaks and the peaks. Preventive measures. Low -risk areas to leave the area or city where the personnel are located should hold a 48 -hour nucleic acid test negative certificate. "Lei Zhenglong introduced that this can further improve the scientific and accurateness of epidemic prevention and control.

Third, in order to further improve the requirements for the monitoring of the epidemic, the ninth edition of the prevention and control plan is clear that the frequency of nucleic acid testing of the encrypted risk professional population will be adjusted to the nucleic acid detection of the personnel directly contact with the entry personnel, items, and the environment to it once a day to increase the antigen detection as the epidemic situation as an epidemic situation. Monitoring replenishment.

"Through a multi -channel monitoring mechanism, further enhance the sensitivity of normalized monitoring and achieve early discovery of cases." Wang Liping said.

The string of the epidemic prevention and control at all times will really be implemented in place

Individual places have insufficient nucleic acid detection frequency during centralized isolation; in some areas, before the entry personnel lift the isolation, the last nucleic acid detection sampling is advanced ... Recently, Shanghai, Jiangxi and other places have found that individual immigration personnel have found that individual immigration personnel have been separated after lift concentration isolation. The positive situation was detected, and the national and regional medical and control experts conducted investigation and analysis and risk investigation on this, and found that individual entry personnel centralized isolation points have weak links and hidden risks in management.

"Each place should strengthen the management of centralized isolation points, and strictly follow the relevant requirements of the ninth edition prevention and control plan to ensure the implementation, landing, and details of the" centralized isolation medical observation+3 Heavenly House Health Monitoring policy. "Lei Zhengzheng.Long said that we must strengthen the standardized management of centralized isolation points, so as to promote information push and closed -loop management throughout the process, and strictly implement home health monitoring.In order to implement the ninth edition prevention and control plan, the comprehensive group of the State Council's joint prevention and control mechanism has recently held a national video conference on the national epidemic prevention and control work, emphasizing that all localities and departments should always tighten the epidemic prevention and control this string, and strictly implement the ninth edition version of the ninth edition.The prevention and control plan will be cleaned up within a time limit.

In the next stage, the Comprehensive Group of the State Council ’s joint prevention and control mechanism will guide the implementation and smooth connection of prevention and control measures in time, and supervise and random inspections of the implementation of various localities in a timely manner, and promote the truly implementation of the ninth edition prevention and control measures.
