On April 12, the joint prevention and control mechanism of the State Council held a press conference, in response to the question of whether it is feasible to choose the third road between "zero clearance" and "lying flat", Wu Zunyou, chief expert of epidemiology of the Chinese Center for Disease Control and Prevention, said that "lying flat" is actually a helpless choice for other countries, and after a variety of attempts, it can not find an ideal strategy to control the new crown, so it is simply "lying flat". The so-called "lying flat" means that in addition to strengthening vaccination, other prevention and control measures are no longer emphasized or simply not done. After some countries "lie flat", the number of cases and deaths has risen sharply, at which time these countries have shrunk back, tightened their prevention and control strategies, and added other prevention and control measures. The mainland's prevention and control practice for more than two years has proved that "dynamic zero clearance" is in line with China's actual conditions and is the best choice for the mainland to control the new crown epidemic in a timely manner at this stage.

In addition, in view of the contagiousness of asymptomatic infected people, how to prevent them from bringing further prevention and control risks to families and communities, Wu Zunyou introduced that when diagnosing a person with asymptomatic infection, some of them are likely to be an incubation period of confirmed cases, and after a period of observation, symptoms will appear, and even develop into severe disease, if they cannot be found in time and treated in time, there will still be risks. Therefore, some of the infected people found at a certain point in time are not the real asymptomatic infected people we are talking about, but the incubation period of the confirmed cases, which is the so-called "asymptomatic infected people" with quotation marks. If home isolation is still at risk, it is mainly manifested in: first, it is possible to continue to spread the epidemic, and second, if he cannot detect the progress of his condition in time, he may miss the best treatment period, and may develop into severe disease and even pose a threat to life.
Wu Zunyou said that centralized isolation has three advantages: First, all asymptomatic and mild cases of centralized isolation and observation are infected, and there will be no problem of cross-transmission and spread. Second, asymptomatic and mild infected people can receive treatment of traditional Chinese medicine during the centralized isolation period, on the one hand, to improve immunity, on the other hand, to prevent these asymptomatic mild diseases from evolving into severe or critical diseases. Third, due to centralized isolation and observation, if the patient has symptoms that develop to severe disease, he can be found in time and referred in time.
