The epidemic in Chongqing has a deep degree of infection and a wide scope. It is the largest epidemic in the city in recent three years. The prevention and control situation is complex and severe. For several days, under the leadership of the Chongqing Municipal Party Committee, all parties have unswervingly implemented the "three unswervingness", and in accordance with the requirements of "epidemic prevention, economic stability, and safe development", adhere to the ninth edition, implement the twenty articles, adjust measures to local conditions, scientifically and accurately carry out the prevention and control work, constantly optimize command and scheduling, improve the efficiency of prevention and control, and promote the implementation of various measures with speed and urgency. Adhere to scientific, accurate, in-depth and meticulous measures to improve detection, flow adjustment, isolation, risk area management, and the treatment of infected people, promote "four should and four do", daily cleaning and daily settlement, make good use of epidemic prevention resources, and strive to block the chain of transmission. We will effectively coordinate epidemic prevention and control and economic and social development, ensure supply and smooth operation, and ensure the operation of urban core functions, so as to ensure people's basic life and medical needs. At present, the prevention and control work in Chongqing has achieved phased results, the rapid rise of the epidemic situation has been effectively curbed, and the prevention and control situation has become stable and good. Chen Min'er, member of the Political Bureau of the CPC Central Committee and secretary of Chongqing Municipal Party Committee, attended relevant activities. Sun Chunlan pointed out that the current epidemic prevention and control in Chongqing is at a critical stage, so we should do a good job in risk research and judgment according to detection and flow survey, and provide scientific and accurate classification guidance. We should not only concentrate resources to promote the development of high-risk areas, but also strengthen the guidance on the prevention and control of streets (towns), villages in cities, and old communities where the epidemic is more serious. We should play a good role in "positional warfare", narrow "encirclement", and constantly consolidate and expand the effectiveness of prevention and control; We will also speed up the progress of dynamic zeroing of the social dimension in areas with less epidemic, implement the ninth version of the prevention and control plan and 20 optimization measures, promote the unsealing of risk areas as soon as possible, expand the coverage of epidemic free communities, and let more people have a sense of gain. The management industry should also manage prevention and control, strengthen the "four party" responsibility, strengthen the management of mobile personnel and key sites, eliminate potential risks, and prevent the emergence of new epidemic outbreak points. We should make every effort to do a good job in medical treatment, scientifically classify the treatment, adhere to standardized and homogeneous treatment, do a good job in the treatment and care of children, the elderly and patients with basic diseases, and promote the early recovery of patients. It is necessary to respond to and solve the reasonable demands of the masses in a timely manner, strengthen humanistic care and psychological counseling, strictly prevent the safety risks in all aspects of epidemic prevention and control, and maintain the order of epidemic prevention and control.
