Adjust the window period!What are the major changes in the ninth edition of the new version of the new crown pneumonia?

The 21st Century Business Herald reporter Wei Xiao Shenzhen reported that with the changes in the virus, my country once again adjusted the epidemic prevention and control measures. On June 28, the State Council's comprehensive group of the joint control mechanism of the new type of coronary virus pneumonia was officially announced in the "New Coronary Virus Pneumonia Prevention Plan (Ninth Edition)" (hereinafter referred to as the "Plan").

At the press conference of the State Council joint defense joint control mechanism held at 3 pm on the same day, Mi Feng, spokesman and deputy director of the Propaganda Department of the National Health Commission, said that the "Plan" fully implemented the general strategy of "external defense input and internal defense rebound" general strategy. And the general policy of "dynamic clearing zero", targeting the characteristics of Omikon's mutant strains, due to the time, the supervision of epidemic monitoring, the isolation management of risk personnel, and the standards for medium and high risk areas are adjusted. Mi Feng also pointed out: "The new version 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."

The main amendments to the "Plan" include four points: first, optimize the time limit and method of adjusting the isolation management of risk personnel; second, the standards for uniform management and control areas and medium and high risk areas; third, improve the requirements of epidemic monitoring; fourth, optimize regional nucleic acid testing Strategy.

The first leader of the first epidemic prevention and control public health expert group and the dean of the Shenzhen Third People's Hospital Lu Hongzhou pointed out to the 21st Century Business Herald that the average incubation period of the Omikon mutation strain was shortened (mostly 2-4 days); Most of the characteristics that can be detected within 7 days, optimize the management period of secrets and entry personnel, can improve the scientific and accuracy of the prevention and control measures of new crown pneumonia, and can also greatly save social resources.

In addition, the unified controlled control areas and medium and high risk areas delineate standards, clarify the requirements, control measures and lifting rules of high, medium and low -risk areas, strong guidance, and strong operability.

Why revise the prevention and control plan?

At present, the new crown epidemic has continued to be popular worldwide. Since this year, the frequency of local epidemic conditions in the country has increased significantly, and the epidemic has a wide range of regions, especially for the Yangtze River Delta, the Pearl River Delta region, as well as the Beijing -Tianjin -Hebei and border port cities. In the impact, the pressure of my country facing "external prevention input, internal prevention and rebound" continued to increase, and the situation of prevention and control is more severe and complicated.

However, the State Health and Health Commission pointed out that in the past month, the overall situation of the prevention and control of my country's epidemic situation has been stable, the number of positive infections has continued to decline, and the number of areas of the epidemic has also decreased. Essence

At present, Omikon mutant strains have become the advantages of my country's overseas input and local epidemics. The existing research reminds that the average incubation period of Omikon variants has been shortened, mostly 2-4 days, more dissemination capacity, the speed of transmission speed Fast, the infection dose is lower, the pathogenic force is weakened, and has stronger immune escape ability.

In order to further guide the prevention and control of new coronary virus pneumonia in various places, we will carefully summarize the practice of preventing and controlling the "New Coronatte Pneumonia Pneumonia Prevention and Control Plan (Eighth Edition)", especially for Omiko's mutant plant Based on the characteristics of fast transmission and high hiddenness, the State Council responded to the amendment of the new type of coronary anti -pneumonia's epidemic prevention and control mechanism to form a "new type of coronary virus pneumonia prevention and control scheme (ninth edition)".

Lei Zhenglong, deputy director of the National Health and Health Commission's Disease Control Bureau and first -level inspector, also pointed out at the above meeting that the National Health and Health Commission revised the prevention and control plan for the following three considerations: First, the changes in the situation of the epidemic situation. The second is the characteristics of virus mutation. Third, a pilot study was carried out in the early stage. According to the decision-making and deployment of the Party Central Committee and the State Council, the State Council ’s joint prevention and control mechanism comprehensive group launched 4 cities in Dalian, Suzhou, Ningbo, Xiamen, Qingdao, Guangzhou, and Chengdu. Zhou's new crown pneumonia's epidemic prevention and control measures optimize the pilot research work.

At the same time, combined with the practice of preventing and controlling work in various places, especially Shanghai, Jilin and other places, it has revised the prevention and control plan.

Lu Hongzhou pointed out that in order to adhere to the overall strategy of "external prevention input, internal prevention and rebound" and the "dynamic clearing zero" general policy, it will further improve the scientific and preciseness of the epidemic prevention and control, make full use of resources, improve prevention and control efficiency efficiency , Coordinate the prevention and control of the epidemic and the development of economic and social development.

In addition, the overall requirements of the "Plan" also clearly adhere to scientific and precise prevention and control, and implement measures "early prevention, early discovery, early reports, early isolation, early treatment" measures. The epidemic control is controlled at the minimum, and the lives of the people's lives and health are effectively maintained, and the prevention and control of the epidemic and economic and social development will be coordinated to the greatest extent.

What is different from the eighth edition?

It is worth noting that the main revision of the "Plan" includes four points. The first is to optimize the time limit and method of adjusting the isolation management of risk personnel; adjust the time and control time of close contact and entry personnel from "14 days of centralized isolation medical observation+7 Heavenly Home Health Monitoring" to "7 -day concentrated medical observation+3 days Home Health Monitoring ". The densely connected tubular control measures were adjusted from the "7 -day centralized isolation medical observation" to "7 Heavenly House Observation Medicine Observation", and the first, 4th, and 7th day nucleic acid testing was detected.

Why adjust from "14+7" to "7+3"? Lu Hongzhou said that the average incubation period of Omikon mutation strain was shortened (mostly 2-4 days); most of the characteristics that can be detected within 7 days, optimized the management period of secrets and entry personnel, which can increase the new crown. The scientific and accuracy of pneumonia epidemic prevention and control measures can also greatly save social resources.

The adjustment of the time of isolation control also has a greater challenge for provinces and cities with more overseas input cases, such as Shenzhen. In this regard, Lu Hongzhou said that Shenzhen is a port city and faces great pressure on prevention and control, but under the guidance of the "Plan", it can better achieve precise prevention and control.

The second is to unify the standards for regulating control areas and high -risk areas (new content); high -risk zones implement "not leaving home, on -site services", and those who have no new infection for 7 consecutive days are reduced to medium -risk zones. Those who have no new infection for 3 consecutive days are reduced to low risk areas. In other regions, there are seven -day concentrated observation of medical observation measures for the history of high -risk districts in the past 7 days.

The central risk zone implemented "no region, peak peaks to take things", and those who have no new infection for 7 consecutive days have been reduced to low -risk zones. In other regions, there are 7 Heavenly House Medical Observation measures for the history of the mid -risk zone in the past 7 days.

The low -risk zone refers to the implementation of "personal protection and avoiding gathering" in other areas (cities, districts, and flags) where the high -risk zone is located. In other regions, there are low -risk districts in the past 7 days, and 2 nucleic acid testing is required within 3 days.

What are the benefits of unified control control areas and medium and high risk areas? Lu Hongzhou said that the unified controlled control area and medium and high risk areas delineate standards, which clarifies the requirements, control measures and lifting rules of high, medium and low -risk areas, strong guidance, and strong operability.

The third is to improve the requirements of the epidemic monitoring; the frequency of nucleic acid testing in the encryption risks, and the nucleic acid detection of the personnel of the inbound personnel, items, and the environment is adjusted to once a day. The detection adjustment was adjusted twice a week. Increase the antigen test as a supplementary method for the monitoring of the epidemic, and the grass -roots medical institutions can increase the antigen detection to the high -risk zone personnel such as suspected patients and the disposal of the epidemic.

The fourth is to optimize the regional nucleic acid detection strategy; clarify the regional nucleic acid testing scheme of different populations, and for cities, cities, and rural areas above millions of people, cities, and general cities, and rural areas, whether the infection source is clear, whether there is community communication risk and transmission after the occurrence Whether the chain is clear and other factors to study and judge, according to the risks, according to the principle of classification, determine the scope and frequency of regional nucleic acid detection.

Lu Hongzhou pointed out that in the improvement of epidemic monitoring, medical institutions have added medical institutions, key institutions and venues, community management populations, centralized isolation places, medical institutions and drug monitoring content; The nucleic acid testing requirements of members, key groups and key places reflect precise management.

此外，相比第八版，《方案》总体要求中增加了“科学精准防控”、“加强源头管控”、“坚持人、物、环境同防”、“提高监测预警灵敏性”、“以The minimum and lowest cost control the epidemic in the minimum range, "maximize the preparation of epidemic prevention and control and economic and social development", etc., laid the "scientific anti -epidemicization, precise prevention and control, and rapid disposal of the entire" Plan "for further optimization of the" Plan ". , Affects minimize "tone.
