In recent days, Sun Chunlan, Vice Premier of the State Council, led a working group to investigate and guide the work of epidemic prevention and control in Chongqing. They went to communities with severe epidemic, shelter hospitals, isolation points, nucleic acid detection points, universities and smooth traffic protection units to investigate the implementation of prevention and control measures on the spot. They went to community prevention and control special classes, nucleic acid detection special classes and transport special classes for many times to learn about the progress. They held a special meeting every night to study and judge the epidemic situation, and exchanged views with Chongqing overnight, It is urgent to promote the implementation of various prevention and control measures. Strive to control the epidemic situation in the shortest time and restore normal production and living order as soon as possible. Chen Min'er, member of the Political Bureau of the CPC Central Committee and secretary of Chongqing Municipal Party Committee, attended relevant activities. Through the joint efforts of all parties, the epidemic prevention and control in Chongqing has achieved phased results, and the efficiency of prevention and control has been constantly improved. The proportion of newly infected people in the city's society has decreased from 63% to 8%. Six districts and counties, including Chengkou, Fengjie and Wansheng, have basically achieved social clearance. Sun Chunlan pointed out that it is necessary to improve the nucleic acid screening program according to the test results, optimize the transfer process, simplify unnecessary links, quickly check and report, scientifically classify and treat positive infections, properly organize the transfer, reception and isolation of "one old and one young", and carefully do a good job of care, rescue and humanistic care. It is necessary to strengthen the on-site flow investigation, and the close contact personnel should be sentenced to the full extent. The resource strength should be further tilted to the areas with severe epidemic situation, and the key points should be tackled as soon as possible to expand the effectiveness. It is necessary to strengthen the responsibility of competent departments and units in the industry, strengthen the risk investigation of key places such as nursing homes, colleges and universities, and prison institutions, as well as mobile personnel such as postal delivery and supply guarantee, and plug the loopholes in prevention and control in time to prevent leakage from getting out of control. We should implement the requirements of "epidemic prevention, economic stability, and safe development", ensure people's livelihood and medical services, strengthen health education and the publicity of the law on the prevention and treatment of infectious diseases, promote the construction of epidemic free communities, and fight the battle of epidemic prevention and control well.
