On August 8, sun Chunlan, member of the Political Bureau of the CPC Central Committee and vice premier of the State Council, went to Henan from Shaanxi to investigate and guide the prevention and control work. In recent days, he has successively visited Erqi District and Zhongyuan District of Zhengzhou City, Yuzhou City of Xuchang City and Tangyin County of Anyang City, where the epidemic situation is serious, to go deep into supermarkets, factories, schools, isolation places, designated hospitals and sealed control communities, so as to understand the origin of flow regulation Community control, centralized isolation, patient treatment, service guarantee, etc. At present, Henan is facing the dual challenge of the import of delta and Omicron strains. The epidemic has affected seven cities, focusing on Zhengzhou, Yuzhou and Anyang. The situation and tasks of epidemic prevention and control in the three places are different, and the prevention and control work is in a critical period, which can not be taken lightly. *** Sun Chunlan pointed out that the overall epidemic situation in Zhengzhou has stabilized and the prevention and control effect has begun to appear. It is necessary to implement differentiated zoning nucleic acid screening, highlight key areas and populations, identify scattered infected persons and risk personnel as soon as possible, eliminate potential risks and realize the "zero" of social aspects. The community transmission risk of the epidemic situation in Yuzhou has not been completely eliminated. We should broaden the idea of tracing the source, carry out flow survey "looking back", knock on the door door door by door in urban villages and other areas, find out the bottom number, press stubble, promote nucleic acid detection, strengthen transportation and isolation, manage and control the close and secondary close personnel in place, and truly stay indoors in the sealed control area to shorten the tail time of the epidemic situation. We should make good use of the situation to ensure the living materials of the people in the sealed and controlled community, classify and ensure the basic medical needs of the people during the epidemic, and ensure that the demands of the people can be responded to and solved in a timely manner. Sun Chunlan stressed that the Omicron virus has fast transmission and strong infectivity, which is a test for the existing prevention and control measures in Anyang. Only when various measures are implemented quickly can it outperform the virus. We should further improve the efficiency of nucleic acid detection and flow investigation, take strict social control measures, block the route of transmission as soon as possible, and strictly prevent the overflow and spread of the epidemic. The management service of isolation points should be in place, and the psychological comfort of isolation personnel and the care of junior students should be strengthened. The clinical symptoms of patients infected with Omicron strain are mainly upper respiratory tract infection. We should pay close attention to preparing special admission hospitals, dispatch national medical experts, strengthen clinical treatment and research, summarize treatment experience and improve treatment plans.
