At present, the epidemic situation in China is still severe and complex. In order to further guide local governments to do a good job in epidemic prevention and control, according to the ninth version of the prevention and control plan and the "20 Article" optimization measures, the Integrated Group of the Joint Prevention and Control Mechanism of the State Council recently released four technical documents, including the Guidelines for Home Health Monitoring of the COVID-19 (hereinafter referred to as the Guidelines). Do not go out unnecessarily, do not restrict the activities of common residents, and do a good job of necessary life security and care services... What is the significance of this Guide, what are the impacts on the daily lives of home health monitoring personnel, and what are the requirements for relevant grass-roots staff? Five questions will help you understand this official guide. Scientific and accurate prevention and control, which operations are more based on the Guidelines? In the past more than a year, the Omikron mutant has evolved into several sub branches, which are more insidious and spread faster. In this regard, our country has been based on the characteristics of virus mutation and the practical understanding of clinical treatment, while preventing and controlling, while studying, while summarizing, while adjusting. "For some possible risk links, the Integrated Group of the Joint Prevention and Control Mechanism has specially formulated four technical documents and proposed preventive and response measures. As long as all regions strictly implement them, epidemic risk can be effectively reduced." Cheng Youquan, Director of the First Supervision Division of the National Bureau of Disease Control and Prevention, introduced the joint prevention and control mechanism of the State Council at the press conference held on November 29. In terms of the applicable objects, the Guide specifies that it includes employees in high-risk positions who have completed closed loop operations, discharge (cabin) personnel of COVID-19 infected persons and other personnel who need home health monitoring as assessed by professionals. Wang Liping, a researcher at the Department of Communication and Prevention of the Chinese Center for Disease Control and Prevention, said that employees in high-risk positions mainly refer to those who have a high risk of exposure and infection during their employment, including those who have direct contact with inbound personnel, goods, including imported cold chain goods and the environment; Workers in centralized isolation places; Medical personnel of fever clinics in designated medical institutions and general medical institutions. These personnel shall operate in a closed loop and strictly implement personal protection and nucleic acid testing. In terms of community service, the Guide requires that street (town) and community (village) staff should strengthen the touch and discharge and information registration, and timely master the information of the people who return to the home health monitoring. For the management of home health monitoring personnel, the Guide emphasizes that during home health monitoring, I should strictly implement the principle of not going out when it is not necessary, and do a good job of personal protection when going out for medical treatment and other special circumstances. "The Guide is not only more hierarchical, but also more humanistic. It ensures the normal life of the people while preventing and controlling the epidemic, and it is more convenient for grass-roots personnel to implement and implement, so as to further ensure that the epidemic prevention and control work is based on and standardized." Liu Yun, chief physician of the Department of Respiratory and Critical Care Medicine in the Second Affiliated Hospital of Xi'an Jiaotong University, said. Does not restrict the activities of fellow residents lead to communication risks? Home isolation medical observation and home health monitoring are both "at home", but due to the different infection risks of these two types of personnel, the requirements for places and management are also different. For the personnel in close contact, the personnel overflowing from high-risk areas, and the employees in high-risk positions who have completed closed loop operations, the "20" optimization measures have shortened the period of centralized isolation, or
