In this round of epidemic, the proportion of asymptomatic infections in is relatively high. In Shanghai, the proportion of asymptomatic infections is even many times higher than that of confirmed cases. How to view this phenomenon and what causes the high proportion of asymptomatic infections in this round of epidemic. Let’s take a look at the interpretation of Liang Wannian, the head of the expert group of the National Health Commission’s leading group for epidemic response and disposal.
Head of the Expert Group of the Leading Group of the National Health Commission’s Epidemic Response and Disposal Work Leading Group Liang Wannian: One reason is the characteristics of the Omickron variant itself, which is higher than the asymptomatic infection rate of Delta . The second is that due to the strict prevention and control measures taken by China, especially vaccination, some people will not experience symptoms even after being infected. This is our prevention and control effect. Third, and more importantly, we have taken measures to detect early and deal with the infection as soon as possible. He may have symptoms, but because we intervened and dealt with it in a timely manner, he did not develop symptoms and blocked the development of the disease. I think it is the combined three factors that have caused the high asymptomatic infections in this round of epidemic in China. In this case, you cannot think that the high proportion of asymptomatic infections is caused by the virus itself. A considerable part of it may be the results of our prevention and control.
Control the epidemic. There is a "triangle" model in science. The arrival of a new round of epidemic has brought great impact on people's lives and work. Nowadays, people in society are asking more and more, when will the epidemic end and the people return to their lives before the epidemic? Let’s continue to look at the observation and analysis of Liang Wannian, the head of the National Health Commission’s leading group for epidemic response and disposal.
Leader of the Expert Group of the Leading Group for the National Health Commission's Epidemic Response and Disposal Work: I believe everyone hopes that the epidemic will end as soon as possible, but the virus and disease themselves are not transferred by our will. When an outbreak comes, how to effectively control it and achieve a balance, we often talk about the "triangle model", which means that the toxicity and harm of diseases and viruses are the same. The second angle is the resistance and ability of the health system. The third angle is public health and social interventions. After the outbreak of the epidemic, these three angles form a "triangle model" and they must achieve the best balance. Theoretically, there are several aspects to the end of the epidemic: 1. Hope that the virus mutation will become weaker and weaker, its pathogenicity and transmission will become weaker and weaker, and its health hazards and threats to people's lives will become smaller and smaller. This is the best. 2. For example, our vaccine is more effective, not only to prevent severe illness and death, but also to prevent infection, and the ability to prevent severe illness and mortality is higher. 3. For example, if there are special drugs, in addition to existing effective drugs, more effective drugs may appear, or even special drugs, which can block the disease in the early stage. 4. Internationally, the epidemic situation in other countries is also eased, and the pressure to prevent imported cases from being reduced, etc. Together, we can discuss when we can adjust our strategies and when we can return to normal life.
