Since the release of the 20 measures to optimize and adjust epidemic prevention and control, all regions are rapidly implementing and refining the implementation plan. In some cities, when determining high-risk areas, the units and buildings should be accurate in time; Some places add more details and temperature in isolation and transportation, nucleic acid detection, medical services, etc. According to the data of the official website of the National Health Commission "Implementing the 'Nine Don'ts' public message board for epidemic prevention and control", the number of complaints from the public dropped by 39% from the 11th to the 16th. In the face of the once-in-a-century COVID-19 epidemic, there is no ready answer to how to do a good job in prevention and control. To constantly optimize and adjust the prevention and control measures, we must fully understand the complexity, difficulty and repeatability of the anti epidemic struggle, proceed from the actual situation of our country, adhere to the principle of stability, adhere to the bottom line thinking, and effectively enhance the pertinence of the work. Faced with the complex situation of prevention and control, all departments in all regions should unswervingly adhere to the people first and life first, unswervingly implement the general strategy of "external defense input, internal defense rebound", unswervingly implement the general policy of "dynamic reset", and fully, accurately and comprehensively implement the decisions and deployment of the CPC Central Committee. In the past three years, China has effectively responded to multiple rounds of global epidemic shocks, protected people's lives and health to the greatest extent, and made significant positive achievements in coordinating epidemic prevention and control and economic and social development. To maintain the hard-earned anti epidemic achievements, we should strengthen analysis, research and judgment while implementing various anti epidemic measures. We should not only continue to rectify the practices of "layer upon layer" and "one size fits all", but also oppose irresponsible attitudes to prevent "letting go". "One seal" is a lazy government. In accordance with the requirements that the epidemic situation should be prevented, the economy should be stabilized, and development should be safe, some places are correcting the practices that are inconsistent with the ninth version of the prevention and control plan and the twenty optimization measures in a timely manner. At present, the special classes for dealing with the "layer by layer overweight" problem in various regions play a leading role in guiding all aspects to further improve the scientific and accurate prevention and control of the epidemic, timely correct outstanding problems such as violations of the "nine prohibitions", and timely correct simple practices such as "expanding the code" and "global silence". Strictly implement the national unified prevention and control policy, implement the territorial responsibility, prohibit "overweight" behaviors such as arbitrarily closing schools and classes, stopping work and production, blocking traffic without approval, arbitrarily closing controls, and not unsealing for a long time, increase the intensity of notification and public exposure, and seriously pursue the legal and regulatory responsibilities for those causing serious consequences. "Let it go" is the shopkeeper. Optimizing prevention and control measures is not to relax prevention and control, nor to relax and "lie down". At present, the necessary epidemic prevention measures cannot be relaxed. Article 20 The optimization measures have adjusted the management and control methods of risk personnel such as close contacts and inbound personnel. The joint prevention and control mechanism of the State Council emphasizes that this is based on the practical evaluation data and risk research and judgment of the ninth version of the prevention and control plan, in order to better concentrate resources and improve the efficiency of prevention and control. To adapt to the characteristics of rapid virus transmission, it is necessary to strictly achieve early detection, early reporting, early isolation, and early treatment, so as to make rapid control and avoid expanding the front and prolonging the time. We should concentrate our efforts on fighting the epidemic in key areas, take more resolute and decisive measures to tackle the problem, curb the spread of the epidemic as soon as possible, and restore normal production and living order as soon as possible. Optimize and adjust epidemic prevention and control measures according to time and situation
