Original title: Video | How to prevent the epidemic this winter under “internal and external attack”?
The question of whether there will be a second wave of new corona epidemics from the fall and winter has always been the focus of public attention, and sporadic epidemics have appeared again in China. How to prevent it? To what extent will the global epidemic affect China?
“China Yangtze River Delta” invited the member of the leading expert group on prevention and control of the Shanghai coronary pneumonia epidemic, Wu Fan, vice dean of the Shanghai Fudan University School of Medicine and member of the expert group on Shanghai new coronary pneumonia prevention and control clinical treatment, Shanghai Public Health Clinical Center Shen Yinzhong, director of the medical department, discussed related issues together.
Will there be a second wave of epidemics in China?
On November 9, Shanghai reported a locally confirmed case. The case took place at the Pudong airport. Yingqian Village, Zhuqiao Town, Pudong New District, where he lived, was classified as a medium risk area. A day later, the Shanghai Department of Disease Control and Prevention announced the investigation of new cases of coronary pneumonia in Yingqian village. 8,717 people have been examined and the results of the nucleic acid tests are all negative. On November 10, a case of new coronary pneumonia was confirmed in Yingshang County, Fuyang, Anhui.
The world, especially Europe and the United States, is facing a second wave of outbreaks on a larger scale. As of November 11, the United States has become the most affected country in the world, with more than 10 million confirmed cases and nearly 240,000 deaths. Epidemiologists believe that the increase in cases may continue for several weeks.
In Europe, data released on the 10th showed that the cumulative number of confirmed cases in France reached more than 1.82 million, and the cumulative number of deaths exceeded 40,000. Italy is not optimistic, with the cumulative number of new cases exceeding 35,000. Today, many European countries have issued blocking orders. French health officials said that if effective control is not achieved, measures such as the closure of secondary schools and the closure of public service agencies cannot be ruled out.
Both Wu Fan and Shen Yinzhong believe that the possibility of a large-scale epidemic in China is very low.
In Wu Fan’s view, in the context of standardized prevention and control, sporadic and occasional cases in China can become the “new normal”, and there should be a “normal heart” in this regard. China’s current prevention and control capabilities and prevention and control network have given us enough confidence to detect, treat and control the epidemic as quickly as possible.
At the same time, it should be noted that it is not easy to trace the origin of the epidemic. For urban prevention and control, elimination is more important than research. “Turn off the fire” and disinfect first, which means that some evidence will disappear. However, cutting the downstream flow means doing a good job of managing close contacts, which is our important successful experience in keeping sparks from turning to fire.
“Diao Chuan Ren” or “Human Diao Chuan”
In this wave of epidemics, the appearance of mink transmission is quite striking. Due to the occurrence of multiple cases of the new mutated corona virus transmitted to humans by farm mink in Denmark, the local government is intensifying the slaughter of farm minks in accordance with the government slaughter order, and the number may reach 17 millions. In addition to Denmark, the United States, Italy, the Netherlands, Spain and Sweden have also found new coronaviruses in mink farms. In this regard, the World Health Organization has indicated that the biosecurity of mink farms should be reviewed on a global scale.
Shen Yinzhong pointed out that the “Diao Chuanren” should attract great attention. The emergence of this case is to remind us that we must pay attention to the existence of the phenomenon of the new coronavirus that spreads from animals to humans, pay attention to the safety of culture organisms, and accumulate more evidence to study the related transmission routes.
Besides “passed by the people”, another possibility is “passed by the people”. Wu Fan specifically noted that in previous studies on the transmission of influenza viruses, it is not uncommon for people to transmit influenza viruses to poultry and livestock. Therefore, a close watch should be made for “person-to-mink” or person-to-person transmission of the novel coronavirus to other animals. The result can have a major impact on future prevention and control measures.
Furthermore, it is worth noting that the previous cases in Qingdao and Tianjin in Shandong were all related to frozen products. Faced with the risk that the transport of the cold chain will become the import of the new corona virus, this week, the joint prevention and control mechanism of the State Council announced a work plan that requires that all sources of imported foods from the cold chain are traceable and their whereabouts can be traced. Trace the entire closed-loop control process.
Wu Fan believes that preventing cold chain epidemics still requires division of labor into various departments and traceability of the entire process. A complete traceable chain or system should be formed at the links of reproduction, food processing, packaging, transportation, etc., so that when an anomaly is discovered, it can be quickly traced and the source found for elimination.
How far is the vaccine from us?
As the most powerful means of infection control, vaccines remain the center of attention.
Currently, 13 vaccines in China have entered clinical trials. Among them, 4 vaccines entered phase III clinical trials. So far, a total of approximately 60,000 subjects have been vaccinated and no serious adverse reactions have been reported.
Globally, Pfizer Pharmaceuticals Co., Ltd. of the United States announced this week that the new corona vaccine developed in cooperation with a German biotechnology company has been shown to be more than 90% effective in phase III clinical trials.
Recently, Shen Yinzhong participated in relevant WHO meetings. According to him, at present, a total of 47 vaccines worldwide have entered clinical studies, of which 10 vaccines have entered phase 3 clinical studies. Although the final results of the effectiveness of Pfizer’s vaccine have not yet have been verified, based on preliminary data in the meantime, the vaccine may have some effect. Additionally, four vaccines in China have entered phase III clinical trials and the outlook is optimistic.
Does the virus mutation affect the effectiveness of the vaccine? Wu Fan believes that virus mutation and vaccine development are always a game. Even if it mutates, the original vaccine does not have a 100% protective effect on the new virus, but it will still have a cross-protective effect and will reduce the symptoms of infection with the new virus.
Is Shanghai’s Legislation to “Wear Masks” a Scandal?
According to the “Shanghai Municipal Public Health Emergency Management Regulations” officially implemented this month, during the infectious respiratory disease epidemic, people who enter public places such as railway stations, buses and subways are required to wear masks and keep social distancing.
Why should the wearing of masks move from personal behavior to the legislative level? Wu Fan said that the contribution of foreign defense and the upturn in domestic defense remain the top priorities of China’s current prevention and control work, and should not be paralyzed. For the general public, it is particularly important for everyone to start for themselves and do a good job of self-protection. Among them, wearing a mask, maintaining social distance, and maintaining good personal hygiene are the “three-piece suits” to consider. In particular, 2 to 4 days before the appearance of a new coronary pneumonia, the virus has the ability to spread, so it is necessary to use laws and regulations to regulate the behavior of the use of scientifically based masks.
