At present, the situation of prevention and control of COVID-19 in China is still grim and complex. The joint prevention and control mechanism of the State Council recently stressed that we should strictly implement the ninth version of the prevention and control plan and the "nine no's" requirements, improve the scientific and accurate level of prevention and control, effectively ensure the normal production and living order of the people, and report on the typical behaviors of simple prevention and control, "one size fits all" and "layer by layer". According to the requirements, the relevant epidemic prevention and control measures were further optimized and adjusted in many places. According to reports, the National Health Commission and the National Bureau of Disease Control and Prevention timely transferred and supervised local inspection and handling of problems reported by the masses every day. These problems are mainly concentrated in three aspects: first, take restrictive measures such as compulsory repatriation and isolation for personnel from low-risk areas; Second, expand the scope of restricted travel from medium and high risk areas to other areas at will; Third, randomly expand the scope of risk groups taking isolation control measures. In addition, in some places, when dealing with the epidemic situation, there are also situations such as charging in isolation places, random silence, "closing the city" instead of control, and restricting people's travel in the form of code attached pop-up windows. Reporters interviewed and found that the phenomenon of simplified epidemic prevention and control, "one size fits all" and "layer by layer" has been rectified in many places. Among them, Zhengzhou City, Henan Province requires precise delineation of control areas to avoid excessive epidemic prevention. According to the information released at the local epidemic prevention and control news conference held on the 6th, Zhengzhou further pinpointed the risk areas to communities, communities and buildings, and made it clear that if the number of newly infected people is less than 2 and they are in the same unit, only the unit will be sealed and controlled, and the entire community will not be sealed and controlled due to the indiscriminate outbreak of individual epidemics, and the very few will be controlled and the majority will be released as far as possible. Taiyuan City, Shanxi Province, requested on the 5th that the epidemic situation should be tracked in real time, the risk level should be determined dynamically, daily research and judgment, daily scheduling should be insisted, and personnel returning to Taiyuan should be checked and controlled according to the requirements of the ninth version of the prevention and control plan. Yuncheng City, Shanxi Province, lifted the control of the last local medium risk area on the 7th, and the normal production and living order was fully restored throughout the city. In Daqing City, Heilongjiang Province, the headquarters office of the local epidemic response leading group issued an announcement on the 5th to adjust the relevant policies for people from outside the city to return to Daqing. Shenzhen, Guangdong Province, held an executive meeting of the municipal government on the 7th to emphasize that the work requirements of "active prevention, early detection, quick disposal, spill prevention, and excellent service" should be earnestly implemented, and the management of key groups and places should be highlighted, so as to continuously improve the scientific prevention and control, precise prevention and control, and humanized prevention and control. Bijie City, Guizhou Province ordered the relevant districts and counties to immediately call off the collection of fees at isolated places and return the fees collected. In Nanchong City, Sichuan Province, the health reminder issued by the local CDC on the 5th has deleted the content of self care for centralized isolation costs. Since the outbreak of the COVID-19, China has adhered to the principle of people first, life first, external prevention input, internal prevention rebound, and dynamic zeroing unswervingly. We have carried out the people's war, the overall war, and the war of resistance against the epidemic, to protect people's life safety and health to the greatest extent, and achieved significant positive results in coordinating the prevention and control of the epidemic and economic and social development.
