China News Online, October 22 (Zheng Yingying) Zhang Wenhong, director of the Department of Infectious Diseases, Huashan Hospital Affiliated to Fudan University, stated at the 2020 Pujiang Innovation Forum on the 22nd that secondary infections are currently not worth discussing, because there are 40 million cases worldwide. Among the infected people, there may be only 9 people who have been infected again. "I think 9 people are relative to 40 million. This issue is not worth discussing for the world that has spread for 9 months."

　　Secondary infections may have special causes. The most important ones are vaccines and drugs

　　Zhang Wenhong believes that the problem of secondary infection has not been finally confirmed. (We have not confirmed) the human immune system will be destroyed before the virus, and will be repeatedly infected by the virus within a year. "Among these nine people, There are still special reasons, either the case, the sequencing, or the patient’s own immunology, but no matter what, it has not become an important scientific issue so far, because it accounts for Only 9 of the 40 million people have seen more such cases so far." He believes that if this problem becomes a problem, more patients will appear. The current world (control the epidemic) The most important thing, the first is the vaccine, and the second is the medicine. Other issues are not yet a problem.

　　The control of the epidemic depends on whether the world can control the epidemic as a whole

　　Zhang Wenhong said that so far, all countries have followed their own practices to control the epidemic to the greatest extent, but some are better controlled and some are slightly worse.

But in the end, the control of the epidemic actually depends on whether the world can control the epidemic as a whole. Otherwise, even if China controls it well, the epidemic will not end because the world cannot be opened up all the time.

　　He said that in the end we have to wait for two points: one is the effective treatment of drugs that reduce the mortality rate of critically ill patients; the other is an effective vaccine, which can protect the very vulnerable people and reduce the mortality rate.

　　"With these two points, the world can truly reopen, so we are all waiting now, waiting for the dawn of technological innovation to truly reveal the horizon." Zhang Wenhong said.

　　He said that so far, we have not seen any drugs or vaccines that have been on the market. Although this time may be very fast, all things have to wait for it to truly emerge, so that all mankind is protected and the world is reopened. In a moment, we can finally take this reassurance pill, he believes that this day will come.

　　Strict prevention and control of imported epidemics in autumn and winter should be no problem

　　Zhang Wenhong said that China’s prevention and control of the first wave of epidemics has been relatively successful, and the second wave of prevention and control is now mainly imported epidemics. “In fact, according to China’s existing prevention and control strategies, in the second wave (epidemic) As the situation has intensified globally recently, China's prevention and control are very ideal."

　　He said that for the overall situation of the imported epidemic, according to the existing strategies, if we can strictly follow it, we still have the confidence to control the imported epidemic.

　　"So far, we have also seen some small-scale outbreaks caused by imported cases in individual areas, very small-scale and small-scale, but they can soon be controlled." He said.

　　He believes that although everyone is very concerned and cautious about imported epidemics in autumn and winter, as long as the original strategy is maintained, there should be no problem. "The so-called influenza and other epidemics in autumn and winter are like this every year. This year, everyone is because of the prevention and control of the new crown meeting. Be more cautious. This year's flu virus should'come as promised' like in previous years, but overall everyone's strategy is also very clear.

　　Zhang Wenhong believes that the main task of the next stage is actually how to break the global imbalance in epidemic control and how to reopen the world as soon as possible. "This requirement is still quite high and requires the cooperation and technological innovation of various countries, including vaccines. "(Finish)
