Recently, the joint prevention and control mechanism of the State Council issued the Notice on Further Optimizing and Implementing the Prevention and Control Measures for the COVID-19 (referred to as the "New Ten Articles"). Over the past few days, various departments around the country have been benchmarking the "new ten items", adjusting measures to local conditions and quickly implementing them. To implement the "New Ten Rules", we need to pay more attention to accuracy. Take the delineation of high-risk areas as an example. The 20 optimization measures previously released pointed out that: "High risk areas are generally defined by units and buildings, and cannot be expanded at will." The "New 10" pointed out that: "High risk areas are defined by buildings, units, floors, and households, and cannot be expanded to residential areas, communities, streets (towns) and other areas at will." Delineating high risk areas and specifying them to households requires that all localities adhere to scientific accuracy and implement them to the letter. Take the variant of COVID-19. According to experts, the current prevalence of COVID-19 in China is dominated by the subfamilies BA. 5.2 and BF. 7 of the Omikron variant BA. 5. The COVID-19 mutants that are prevalent in different regions at the present stage are different. Is there any slight difference in their infectivity and infectivity, and will the psychological reaction to the public also be different? In this regard, all localities should also comprehensively evaluate and accurately respond. For all departments around the country, the "dynamic" optimization of epidemic prevention and control measures puts forward higher requirements and heavier burdens, which makes it more necessary to show the level of governance. For example, the "New Ten Rules" require that people's basic demand for drugs be guaranteed, and local pharmacies should operate normally and not be closed at will. It is not allowed to restrict people to buy over-the-counter drugs such as antipyretic, cough, anti-virus, and cold treatment online and offline. Then the problem arises. The pharmacy has started to operate normally. Can the drug supply keep up? For another example, as the number of fever clinic visits and flu like cases has increased significantly, how can medical resources be used to ease public anxiety? In addition, a large number of people infected with COVID-19 choose to rehabilitate at home. They have a greater demand for antigenic reagents. How can we meet this reasonable demand? Thinking is all a problem; Doing is the answer. How to do it, how to do it in the hearts of the masses, how to do it more effectively, is not easy. In the final analysis, it still needs to focus on precision. Recently, a lot of places have stopped large-scale nucleic acid testing, which is an optimization move, but there are still some people who cannot do without nucleic acid testing because of their work needs. The number of nucleic acid spots in the society has been greatly reduced, making them search all over the city, which is often time-consuming and difficult to achieve. This reminds us that each specific arrangement should listen to the voice of the masses, and consider more comprehensively in the implementation process to avoid the disconnection or dislocation of measures. It is worth mentioning that at present, many places adhere to the problem orientation, and achieve the maximum effect of epidemic resistance through precise attack and classified policy. Whether it is to improve the hierarchical diagnosis and treatment service system, or require the city's hospitals above the second level to set up fever clinics; Whether it is to supplement 108 Chinese and Western medicine varieties or to put 25 million antigen detection reagents into the market at one time, it has responded to the expectations of the masses, stabilized the hearts of people and played a cohesive role. It should be said that prevention and control, adjustment and capacity building are the logic of epidemic prevention that we must adhere to and the experience of prevention and control that has proved to be very effective. China has a large local area and a large population
