She stressed that the CPC Central Committee and the State Council attach great importance to the epidemic prevention and control in Xi'an and are very concerned about the health and safety of the people of Xi'an and Shaanxi. *** At present, the epidemic situation in Xi'an is severe and complex, and it is in a critical period of prevention and control. Sun Chunlan stressed the need to strengthen the organization of nucleic acid screening, optimize the organization and connection of sampling and testing links, improve the reporting speed of test results, take more targeted and powerful prevention and control measures, and isolate risk personnel. At present, the risk of community communication still exists in Xi'an. It is necessary to speed up the flow adjustment, quickly lock the risk personnel, pre allocate more isolation rooms, strengthen the connection of community, transfer and isolation points, control the close contacts in place at the first time, achieve daily cleaning and daily settlement, and effectively block the spread of the epidemic. In view of the aggregated epidemic in Xi'an universities, colleges and universities have established special classes for prevention and control, compacted territorial and departmental regulatory responsibilities, quickly carried out risk investigation, concentrated and isolated all close contacts, timely killed the environment, strictly prevented the recurrence of aggregated epidemic, and properly solved the problems of foreign personnel stranded in Xi'an, such as postgraduate entrance examination students. At present, the material supply guarantee in Xi'an is sufficient. The key is to enrich the community work force, open up the "last 100 meters" of service guarantee, and solve the residents' living guarantee and medical demand. We should treat and care every patient carefully, adhere to homogeneous and standardized treatment, do a good job in nutritional security, psychological counseling and humanistic care, and help patients recover as soon as possible. The people are very supportive and cooperative in epidemic prevention and control. We have sufficient protective materials, rapid detection means and effective treatment plans, especially the institutional advantages of the party's leadership. As long as we resolutely implement the general strategy of "external defense input and internal defense rebound" and the general policy of "dynamic zeroing", compact the "Four Party" responsibilities and implement the requirements of "four early mornings", If various prevention and control measures are carefully implemented and put in place, the epidemic will be controlled as soon as possible.
