November 12, at the Joint Prevention and Control Mechanism of the State Council press conference, Mi Feng, spokesperson of the National Health Commission and deputy director of the Publicity Department, introduced that yesterday, the Comprehensive Group of the State Council Joint Prevention and Control Mechanism of the State Council issued 20 measures to further optimize the prevention and control of the new crown pneumonia epidemic. Article 20 optimization measures are the improvement of the ninth edition of the prevention and control plan. is not to relax prevention and control, nor is it to relax or “live”. is to further improve the scientificity and accuracy of prevention and control, and to protect people’s lives and health to the greatest extent and minimize the impact of the epidemic on economic and social development.
We must unswervingly put people first and life first, unswervingly implement the overall strategy of "preventing imports from outside and preventing rebound from inside", and unswervingly implement the general policy of " dynamic zeroing ". We must adhere to science and precision, base ourselves on prevention and early, deal with sudden outbreaks with rapid system and speed, and strictly prevent the spread of the epidemic and large-scale rebound of the epidemic. We must make every effort to ensure the production and living service of the people, effectively meet the people's basic living and medical treatment needs during the epidemic response period, and solve the people's actual difficulties. We must resolutely overcome simplicity and "one-size-fits-all" approach, resolutely rectify and increase efforts at all levels, and solve the problems reflected by the masses.
Twenty measures can significantly alleviate some bottlenecks and obstacles in handling the epidemic
Deputy Director of the National Health Commission Lei Haichao introduced that the continuous optimization and adjustment of the current epidemic prevention and control policies is also the work rhythm and style that has been adhered to in the past two years. Continuously optimizing epidemic prevention and control measures is not to relax epidemic prevention and control work, but to emphasize more scientific and accurate, and to keep pace with the times. We must optimize and adjust epidemic prevention and control measures based on the evolution and change trends of the virus, the improvement and improvement of actual prevention and control capabilities, as well as the accumulated experience and understanding of clinical treatment. The general requirement is to implement the requirements of "the epidemic must be prevented, the economy must be stabilized, and development must be safe", so as to prevent the epidemic, and minimize the impact on economic and social development and people's livelihood service guarantee as much as possible.
Since the outbreak of the new crown epidemic, my country has continued to follow up on the global epidemic situation and virus mutation characteristics, and conduct dynamic assessments in combination with the implementation effect of prevention and control measures. Relevant experts have done a lot of effective research in this regard. Through more than two years of prevention and control practice, I have experienced several challenges of clustered epidemics and accumulated a lot of prevention and control experience. I have gained a new understanding of the transmission laws of the virus and the characteristics of clinical treatment. In addition, new technological progress has also been made in vaccine research and development, drug research and development reserves, etc. Therefore, we must adjust and optimize prevention and control measures according to the times and situations, and continuously improve the scientific and accurate level of prevention and control. can be said that every time the optimization and adjustment of prevention and control measures is very cautious, and it has been scientifically proven by experts to ensure that it is proactive, stable and controllable.
my country's population is huge, especially the number of vulnerable people, especially the elderly population accounts for a large proportion in my country. These are the basic national conditions. Moreover, the total amount of medical and health resources is relatively insufficient, and the distribution between regions and between urban and rural areas is not balanced enough. Based on our evaluation results of the implementation of policies such as the ninth edition of the prevention and control plan, and after in-depth research and demonstration by experts, twenty optimized and improved policy measures have been proposed. The measures after optimization can significantly alleviate some bottlenecks and obstacles encountered in epidemic response in various places. For example, , isolation resources are relatively tight and isolation rooms are insufficient. In addition, the pressure on is very high in terms of , and the personnel for are relatively insufficient.For example, this time we canceled the judgment of close contacts, which can better concentrate the energy and time of epidemiological investigations of personnel to a certain extent to make the investigation and risk control work of risk areas and close contacts better, and can control the epidemic to the smallest range in the shortest possible time at a lower cost, and balance the relationship between our epidemic prevention and control and economic and social development. Therefore, such adjustments and optimization are based on scientific understanding and new achievements based on evidence-based research. This is not relaxation, nor is it "lying down", but we must do a good job in our epidemic prevention and control and handling work more accurately and scientifically.
National Disease Control and Prevention Responds to why
close contacts, medium-risk area judgment
0 Deputy Director of the National Disease Control and Prevention introduced that after the release of the twenty optimization measures based on the ninth edition of the prevention and control plan yesterday, it attracted widespread attention. Based on the few things you pay special attention to, I will introduce you to why you need to adjust.
close contact management measures have been changed to "5+3"
close contact management measures for . The original "7+3" was 7-day centralized isolation and 3-day home health monitoring, and was changed to "5+3", that is, 5-day centralized isolation and 3-day home isolation.
On January 8, Omickron began to become popular in my country. We began to formulate the ninth version of the prevention and control plan, and it took shape by March. From April 5 to May 5, we piloted the prototype of the ninth edition in seven cities across the country. At that time, the main epidemic strains in my country were Omickron BA.1 and BA.2. The results of the pilot were that after the last exposure of -positive infection in close contacts, the proportion of positive tests within 5 days was 89.1% and 97.3% in 7 days was 7 days. So the ninth edition is "7+3".
After the official release of the ninth version of the prevention and control plan on June 28, the plan was evaluated in July and August. At that time, the main popular strains in my country were Omickron BA.5, BA.5.2, and BA.2.76. The evaluation found that the proportion of positive tests for close contacts within 3 days was 81.4%, 90.1% in 4 days, 94.5% in 5 days, and 99.7% in 7 days. Based on these results, the quarantine period is further optimized to "5+3".
started from the first version, and continued to the ninth version and the optimized version to the present. It was originally 14 days, but later it became "14+7", later it was "7+3", and now it is "5+3", which is a gradual process. This process sounds like there are two days of centralized isolation, which can save us about 30% of centralized isolation resources. At the same time, because the maximum incubation period of Omickron is 8 days, we use "5+3".
no longer determines the secondary close contact
evaluation found that the positive detection rate of secondary close contact is very low, about 3 out of 100,000 people. By timely determining and controlling close contacts, the positivity rate of secondary close contacts can be reduced. According to this situation, if you ignore the close contacts or do not judge, you can save a lot of service guarantee resources. When we introduce public policies, we must choose the least of the two evils, so we will no longer determine the second close contact.
Cancel the judgment of medium-risk areas
Since the outbreak of the new crown epidemic in Wuhan, the demarcation of risk areas has been adjusted. For example, it was originally called the lockdown area, the control area, and the prevention area. In the eighth version, it was called the high-risk, medium-risk, and low-risk area. The ninth version was unified into high-risk, medium-risk, and low-risk areas. After the practical application of the ninth edition and the evaluation in July and August, it was found that the positive detection rate in the medium-risk area was 3/100,000, and the second close contact mentioned just now was 31/100,000. We think it's risky, but not big. At the same time, after the medium-risk zone was divided, there were more people under control and epidemic prevention personnel were consumed. Therefore, in this case, it is also the minority of the two evils, and it is decided to cancel the medium-risk area.
For example, spillovers in high-risk areas were originally quarantined for 7 days, but now it has been transferred to 7 days of home quarantine. The risk of spillover personnel is about 49/100,000 after assessment, but these people are detected within 7 days after the risk area is designated. We have changed the 7-day centralized isolation of people spilled out in high-risk areas to 7-day home quarantine, considering that he can manage and save centralized isolation resources after he arrives in the community.
Closed-loop management High-risk personnel management for operations
Everyone also pays attention to high-risk personnel in closed-loop management operations, changing from the original 7-day centralized isolation or 7-day home quarantine to 5-day home health monitoring. The assessment found that if high-risk personnel in closed-loop management strictly implement closed-loop management measures, the positive infection rate is very low, only 16/100,000, which is lower than the medium-risk and secondary secrets mentioned earlier. In this case, we feel that it can be adjusted to 5-day home health monitoring .
All adjustments are based on them. Maybe when you hear the original "7+3" changed to "5+3", you think it's loose? In fact, not only does it not relax, but it has higher requirements. These adjustments require us to carry out prevention and control more scientific, standardized and faster in prevention and control work, to control key risks that should be controlled, to implement what should be implemented, and to resolutely cancel what should be cancelled, make full use of existing resources to improve prevention and control efficiency, and to better coordinate epidemic prevention and control and economic and social development. Interpretation of disease control in
incoming personnel control and nucleic acid testing
Researcher at the China Center for Disease Control and Prevention Department of the China Center for Disease Control and Prevention introduced that in light of the current development and changes in the global COVID-19 situation and some new features of the new coronavirus, in order to better coordinate China's foreign import prevention and international exchanges and facilitate personnel exchanges, according to our previous assessment of the prevention and control measures of incoming personnel and the evaluation results of the ninth edition of the prevention and control plan practice, in the case of strictly preventing imports from outside, four aspects have been optimized and adjusted.
canceled the inbound flight circuit breaker mechanism , and adjusted the negative nucleic acid test certificate twice within 48 hours before boarding to the negative nucleic acid test certificate once within 48 hours before boarding.
With the widespread spread of the epidemic abroad, the infection rate of the population is generally high. In our evaluation, we found that in the population that leads to the positive nucleic acid test for the first time after entering the country, the proportion of infections in the past is very high. In this way, we adjusted the criteria for determining positive detection of incoming people.
Referring to the experience of epidemic prevention and control of the Beijing Olympics and Chengdu World Table Tennis Championships, an isolation-free closed-loop management area has been established for incoming business and specific incoming personnel in sports groups, that is, "closed-loop bubble" . For Chinese and foreign personnel in the closed-loop management area without isolation, they must strictly implement protection requirements such as closed-loop management, personal protection and nucleic acid testing, and strictly prevent "breaking the ring".
The incubation period of the new Omickron variant strain of was further shortened . At the same time, in order to prevent the risk of cross-infection at centralized isolation points, the isolation control period for incoming personnel was adjusted to "5 days centralized isolation + 3 days home isolation".
