Recently, the number of newly confirmed cases and asymptomatic infections in China has continued to decline, but the local transmission has not been completely blocked in some places, and the situation of epidemic prevention and control is still severe and complex. How can the community improve the ability of prevention and control? How to build a "disease-free community"? Relevant experts of the joint prevention and control mechanism of the State Council gave authoritative answers. Liang Wannian, head of the expert group of the epidemic response and disposal leading group of the National Health Commission, said that the community is the frontier of prevention and control, the first line of defense and the most basic unit for the implementation of various prevention and control measures. "It is an accurate and effective disposal method to divide the sealed control area, control area and prevention area and take different prevention and control measures." Wuhao, the leader of the community prevention and control expert group of the National Health Commission on the COVID-19 and the dean of the school of general medicine and continuing education of Capital Medical University, said that in view of the new characteristics of the Omicron mutant, the relevant departments are further speeding up the time of closure, management and control. At the same time, they are taking temporary control measures to prevent risk overflow through the strategy of rapid management and rapid screening. When the risk is removed, it will be quickly removed. According to different local conditions, the prevention and control strategies and measures are also constantly optimized. All localities are making more use of information technology means. For example, technologies such as place code and electronic fence are widely implemented in public places to improve the efficiency of community prevention and control. Wu Hao said that community prevention and control should achieve "four early", give full play to China's institutional advantages, compact the responsibilities of four parties, and build a situation of group prevention and control. Liang Wannian believes that there are several points to be implemented to further improve the ability of community prevention and control—— First, make emergency plans to deal with different epidemic situations and different prevention and control states; Second, widely carry out the work of creating "epidemic free community"; Third, compact the responsibilities of enterprises and institutions in the community and arrange prevention and control measures in advance; Fourth, pay more attention to key groups, regions and units. How to create a "disease-free community"? Wu Hao said that all localities have had a lot of experience in creating "epidemic free communities". The establishment of "epidemic free community" includes six links: clearing, cleaning, health, care, mobilization and incentive—— Zero clearing means that there are no new positive infected persons, asymptomatic infected persons or close contacts that should be isolated within a latent cycle. All personnel should complete at least one round of nucleic acid test for all staff, and the results are negative. Cleanliness refers to standardizing cleaning and disinfection, strengthening the disinfection of key areas and key parts, and maintaining the cleanness and sanitation of the environment. Health means to comply with epidemic prevention requirements, guide residents to actively participate in novel coronavirus vaccination, take the initiative to report personal epidemic related matters, carefully cooperate in nucleic acid testing, and strengthen residents' health education. Care means to find out the basic number of special groups in the community, improve the accounts, deeply understand the different situations and needs of key groups in the community, clarify the content of assistance, and implement accurate care and assistance. Mobilization refers to fully tapping the strength of Party members and volunteers in the community and establishing a mass prevention and control mechanism in the community under the guidance of Party construction. Incentive refers to comprehensively promoting the sinking of government organs, enterprises, institutions and community cadres to participate in the establishment of "epidemic free community" and form a long-term mechanism for building a healthy community. Liang Wannian said that more than two years of prevention and control practice has proved that doing a good job in community prevention and control can effectively block the spread of the epidemic and achieve "dynamic clearing" as soon as possible.
