How to further improve precision prevention and control?

First, scientifically and accurately divide the risk areas. According to buildings, units, floors and households, high-risk areas shall be designated, and shall not be expanded to residential areas, communities, streets (towns) and other areas at will. No temporary blockade in any form is allowed. The second is to further optimize nucleic acid detection. Not according to the administrative region for all the nucleic acid testing, further narrowing the scope of nucleic acid testing, reduce the frequency. According to the needs of epidemic prevention work, antigen testing can be carried out. Employees in high-risk posts and high-risk areas should carry out nucleic acid testing according to relevant regulations, while others are willing to do all the testing. Except for special places such as nursing homes, welfare homes, medical institutions, child-care institutions, primary and secondary schools, it is not required to provide negative proof of nucleic acid testing and not to check the health code. Important organs, large enterprises and some specific places can determine their own prevention and control measures by the territory. Cross-regional migrants will no longer check the negative certificate of nucleic acid detection and health code, and will no longer carry out landing inspection. The third is to optimize and adjust the isolation method. First, scientifically and accurately divide the risk areas.
