Recently, the local epidemic situation in China has shown the characteristics of many points, wide range and frequent occurrence. All localities and departments are paying close attention to various epidemic prevention work and should curb the spread of the epidemic as soon as possible. What do you think of the current situation of prevention and control? How to do precise prevention and control? Why should China adhere to dynamic clearing? Novel coronavirus pneumonia expert response team leader Liang Wannian was interviewed by the reporters on the hot topics of social concern. "All measures for normalized prevention and control should be strictly implemented as rigid requirements." Liang Wannian said, "to prevent and control the epidemic, we must first build a strong defense line, without the slightest relaxation and paralysis." What do you think of the prevention and control situation? Recent frequent outbreaks do not mean that the epidemic prevention strategy is invalid Since March, the frequency of outbreaks in China has increased significantly, the number of infections has increased rapidly, and the scope of infection has been expanding. In this regard, Liang Wannian said that the Omicron mutant has faster transmission speed and stronger concealment. From a global perspective, it has brought about a rapid rise in the epidemic level. "At present, there are many epidemic points, a wide range and frequent outbreaks, which does not mean that China's prevention and control strategies, guidelines and measures are invalid." Liang Wannian said that after the epidemic of Omicron mutant, the epidemic level of many countries and regions in the world has increased exponentially in a short time. "However, the epidemic level in China has risen slowly, which is precisely because we have taken a series of effective intervention measures to curb the rising trend of the epidemic." China has a vast territory, the differences in medical and health conditions are not small, and the absolute number of the elderly population is huge. Prevention and control experts have always been highly vigilant against the risk of the spread of the epidemic. "COVID-19 is very cunning. We have not been able to do a single case at present." Liang Wannian said, but we must recognize the potential harmfulness of the virus, and we must make great determination and efforts to control the epidemic as soon as possible so that it will not cause sustained social transmission and widespread epidemic. How to do precise prevention and control? The key is early detection and early disposal At present, the response and disposal of the epidemic situation in each epidemic area is being carried out in an orderly and powerful manner, and efforts are being made to achieve "all inspections should be carried out", "all intervals should be separated", "all treatment should be carried out" and "all management should be carried out", so as to eliminate the social aspect as soon as possible. "As long as the epidemic is found, we have a series of measures to contain the epidemic in the bud." Liang Wannian said that the key is how to achieve early detection and ensure early disposal after discovery. Liang Wannian said that first, strengthen monitoring, especially for key places and key groups, strengthen daily monitoring and normalized prevention and control requirements, improve the multi-point trigger early warning mechanism and improve the timeliness of discovery. Second, quick shot. Once the epidemic situation is found, the territorial Government, departments and units must quickly implement the prevention and control requirements, early report, early diagnosis and early isolation. At the same time, we should also be accurate, including accurate flow regulation, accurate identification of close contacts, accurate division of control areas and sealed control areas, strive to achieve the maximum prevention and control effect at the least cost, and minimize the impact of the epidemic on economic and social development. "I'm afraid of laziness, hesitation or fluke." Liang Wannian said that we should break the illusion that "without intervention, the spread of the virus will slow down". If it is found late or intervention measures are not taken in time after discovery, the virus will spread exponentially. Why insist on "dynamic reset"? It's too early to judge "pandemic influenza" Adhering to the general strategy of "external defense input and internal defense rebound" and the general policy of "dynamic clearing", China is taking decisive measures to control the local epidemic as soon as possible. Why insist on dynamic clearing? Liang Wannian said that it is too early to regard the epidemic caused by the Omicron variant as "influenza major". For individuals, the probability of severe illness may decline, but Omicron spreads rapidly and the absolute number of infected people is large. As a whole, the number of severe illness and death will be high, which is still a great harm. "Adhering to dynamic clearing is also to consolidate our hard won achievements in prevention and control." Liang Wannian said that over the past two years of prevention and control practice, we have formed a set of ideas, strategies and specific measures to fight the epidemic, effectively protect the people's health and life safety, and effectively balance the relationship between epidemic prevention and control and economic and social development. "The results are hard won and must be cherished. There can be no relaxation and paralysis at this time.". Liang Wannian said that the essence of dynamic zeroing is fast and accurate. If we do not pursue dynamic zeroing for each epidemic, the spread in society will add up, continue to connect, and finally form a large-scale rebound. "After the occurrence of cases and epidemic situations, we can quickly identify and deal with them, quickly cut off the epidemic transmission chain, and accumulate small victories into big victories. On the whole, we will gradually move towards the goal of dynamic clearing." Liang Wannian said. (Xinhua News Agency)
