Standardize nucleic acid testing and scientifically delineate risk areas
2022-11-22
Recently, the Comprehensive Team of the Joint Prevention and Control Mechanism of the State Council issued four documents, including the Implementation Measures for the Detection of Nucleic Acids for the Prevention and Control of the Neocoronal Pneumonia Epidemic, the Plan for the Delimitation and Control of the Risk Zones for the Neocoronal Pneumonia Epidemic, the Guidelines for the Medical Observation of the Neocoronal Pneumonia Epidemic in Home Isolation, and the Guidelines for the Health Monitoring of the Neocoronal Pneumonia Epidemic in Home, to further guide local departments in the prevention and control of the Neocoronal Pneumonia. The Measures for the Implementation of Nucleic Acid Testing for the Prevention and Control of Neocoronavirus Pneumonia requires that in areas where there is no epidemic, nucleic acid testing should be carried out for risk posts and key personnel in strict accordance with the scope determined in the Prevention and Control Plan for Neocoronavirus Pneumonia (Ninth Edition). The scope of nucleic acid testing should not be expanded. Generally, nucleic acid testing should not be carried out for all staff in accordance with administrative regions. In the process of epidemic disposal, on the basis of epidemiological investigation, the scope, frequency and sequence of detection population shall be determined according to the size of the population in the epidemic area, whether the source of infection is clear, whether there is community transmission risk, whether the transmission chain is clear and other factors. If individual cases and asymptomatic infected persons have a low risk of transmission to their places of residence, workplaces and activity areas, close contacts have been timely controlled, and it is determined that there is no risk of community transmission, regional nucleic acid testing may not be carried out. After the outbreak of the epidemic in provincial capital cities and cities with a population of more than 10 million, it is determined through flow of research that the transmission chain is unclear, there are many risk sites and risk personnel, and the mobility of risk personnel is large. When the epidemic is at risk of spread, the epidemic area carries out a full nucleic acid test every day. After three consecutive nucleic acid tests, no one with social infection is detected, another full nucleic acid test is carried out every three days. If no one with social infection is detected, the full nucleic acid test can be stopped. In other areas where the infected people have frequent activities and stay for a long time, a certain area can be designated to carry out nucleic acid testing for all the people based on flow survey research and judgment. In principle, the whole staff nucleic acid test shall be carried out once a day, and the whole staff nucleic acid test can be stopped if there is no social infection after three consecutive nucleic acid tests. When the epidemic situation is spread across a wide range of communities, the provincial epidemic prevention and control mechanism will decide whether to carry out nucleic acid testing for all staff in the city. According to the requirements of the New Coronary Pneumonia Epidemic Risk Zone Delineation and Control Plan, the risk zone should be scientifically defined. Adhere to the principle of "prevention first, prevention and control combined, scientific according to law, and classification by level", and realize the organic combination and rapid transformation of standardized precise prevention and control and emergency response to epidemic situations. In case of local epidemic, the counties (cities, districts and banners) where the cases and asymptomatic infected persons are located should be accurately divided into high-risk areas and low-risk areas as soon as possible. All forces should be coordinated, classified management measures should be implemented, and risk levels and management and control measures should be updated dynamically according to the epidemic situation and actively released to the public. In the process of epidemic management, if the transmission risk of individual cases and asymptomatic infected persons to their places of residence, workplaces and activity areas is low, the close contacts have been timely controlled, and it is determined that there is no community transmission risk, the risk area may not be designated; In counties (cities, districts and banners) where no local epidemic has occurred, it is necessary to effectively implement various measures for normalized epidemic prevention and control, without the need to delimit risk areas.
