How to deal with the epidemic during the Spring Festival? Expert: the more accurate the prevention and control, the higher the efficiency and the lower the cost
2022-01-24
According to the latest report of the press conference of the joint prevention and control mechanism of the State Council on January 22, the Omicron strain has replaced the delta strain in most countries with available data. Who also reminded that Omicron may not be the last variant, and there is still a high degree of uncertainty about the direction of variation in the future. Recently, there have also been reports of local epidemic situations infected with Omicron strain in China, and some epidemic situations are caused by international document express delivery. Facing the upcoming Spring Festival, how to avoid "one size fits all" and prevent the epidemic from "making a comeback"? How do experts judge the transmission route of Omicron virus? There are "zero new cases" in many places, the epidemic is gradually coming to an end, and it is unlikely to make a comeback When introducing the current epidemic situation, he Qinghua, a first-class inspector of the disease control bureau of the National Health Commission, said that a number of local clustered epidemics in China had shown a good trend. On January 21, Tianjin was cleared of social cases for the first time, Zhengzhou and Xuchang in Henan Province were cleared of new cases for the first time on January 20, and Xi'an in Shaanxi Province was cleared of new cases for the first time on January 18. It has entered the closing stage, and the risk of community transmission of the epidemic in many other places is also gradually reduced. "Facts have proved that the prevention and control strategies and measures adopted by China are effective and in line with China's reality." Liang Wannian, head of the expert group of the epidemic response and disposal leading group of the National Health Commission, said that China's epidemic prevention and control can better take into account the epidemic prevention and control and socio-economic development from the emergency containment stage of the sudden epidemic, to the exploration stage of normalized prevention and control, and then to the current "dynamic clearing" stage of the whole chain prevention and control. "Even if there is an epidemic, we can quickly find it, quickly delimit the risk area and quickly deal with it. Therefore, on the whole, it is unlikely that a large-scale epidemic will return due to the flow and gathering of people during the Spring Festival holiday." Liang Wannian said. More accurate, taking into account the Spring Festival and epidemic prevention and control At present, China's prevention and control strategies and measures can basically achieve rapid disposal and eradication of the epidemic situation within 1-2 longest incubation periods. The more accurate and efficient the prevention and control, the lower the cost of prevention and control, and the more it can affect life to the minimum. "At first, our prevention and control was based on provinces. Later, we gradually divided high, medium and low-risk areas based on prefectures, cities and counties. Now we are gradually accurate to streets, communities and even gatehouses." Liang Wannian said that accurate prevention and control and accurate protection of people's daily needs such as life and medical treatment make epidemic prevention and control more temperature and humanistic care. Liang Wannian called on local governments to avoid "one size fits all" to the greatest extent through accurate epidemiological investigation, accurate delineation of close contacts and accurate delineation of control scope during the Spring Festival. Five "first time", so that the epidemic can be detected earlier Recently, there have been several clustered epidemics in China with long hidden transmission time. How to improve the ability of early detection of epidemics? In response to this question, he Qinghua said that early detection is the top priority in implementing the work of "early detection, early reporting, early isolation and early treatment". China has established a multi-point triggered monitoring and early warning mechanism by improving the frequency and quality of nucleic acid detection for key populations, giving play to the role of "sentinel" such as fever clinics, and improving the multi-point triggered monitoring and early warning mechanism, Improve the timeliness and accuracy of information research and judgment, and try to find the potential infected people in the key population, the potential infected people and the potential infected people in the community as soon as possible. In addition, all localities also resolutely implement the policy of "reporting every positive, reporting every positive and checking every report". While reviewing the positive copies of the initial diagnosis, they should simultaneously start emergency disposal measures such as flow regulation, nucleic acid detection, isolation point arrangement and community control, so as to dispose of the confirmed cases as soon as possible. In view of the epidemic situation of Omicron variant, the National Health Commission will carry out virus gene sequencing on all qualified positive samples, strive to find the cases of Omicron variant at the first time, and take targeted prevention and control measures in time. The dissemination of Omicron's documents needs to be further studied In response to the local infection caused by the Omicron virus strain in Haidian, Beijing by international document express, he Qinghua cited the expert research and judgment analysis conclusion that at present, the evidence of infection of domestic personnel caused by non frozen entry items is not sufficient, which needs to be further studied, and the epidemic prevention and control risks need to be closely observed and evaluated. He Qinghua explained that under normal temperature, COVID-19 degrades in a short time and loses its infection activity. On the surface of different articles, the survival time of virus is also different. The survival time of materials on paper towels and printed materials is short, generally not more than 24 hours. Conditions of low temperature, humidity, airtight and high virus concentration may prolong the time of virus survival on the surface of the object. Commonly used disinfectants can rapidly inactivate COVID-19. From the practice of global research and prevention and control, COVID-19's infection through respiratory tract is mainly caused by the close contact between people. The infection of people caused by contaminated products is not the main way of spreading COVID-19. The key point to control COVID-19 is still to prevent communication between people. "Nevertheless, we should pay attention to it tactically, do not take chances, do not underestimate the enemy, do not relax, and strictly implement a series of daily prevention and control measures." He Qinghua said. (outlook new era)
