“Wuhan is the place where the epidemic was discovered, not the place of origin.” On November 19, at the online academic conference “New Crown Attack: Cognition, Prevention and Control, and Prognosis” jointly organized by Cell Press and the Beijing Municipal Commission for Science and Technology, Zeng Guang, a member of the think tank of high-level National Health Commission and former chief epidemiology scientist at the Chinese Center for Disease Control and Prevention, believes that the existing evidence can only draw the above conclusion.
Why was the epidemic first discovered in Wuhan? Zeng Guang explained, “The reason is that since 2003, China has built a pneumonia of unknown cause monitoring and reporting system, and our surveillance and monitoring capacity is among the highest in the world. We maintain a high level of vigilance.” He also mentioned that in 2005, he himself participated in the detection. An unexplained pneumonia epidemic ensued, which later turned out to be an atypical outbreak of primary pneumonic plague. “China has this reporting system, which is why medical workers in Wuhan first mentioned pneumonia of unknown cause.”
Zeng Guang emphasized that previous investigations of the new corona epidemic in Beijing, Dalian and Qingdao have shown that it is not ruled out that foreign cold fresh food and its packaging can hide the virus from entering China, and that “it was not downloaded since Wuhan at the time and was also broadcast from abroad. “
In fact, the current traceability of the new coronavirus is still very difficult, but some studies have revealed some information. Recently, the results of a study published by the National Cancer Institute in Milan, Italy, showed that the institute detected antibodies against the new coronavirus in the blood samples of some residents collected in September last year. This means that the spread of the new corona virus in Italy is long before February.
In response to the view that the novel corona virus had spread abroad prior to the outbreak in Wuhan, Chinese Foreign Ministry spokesman Zhao Lijian said at a regular press conference on November 17 that we have seen and heard about the international outbreak of new corona pneumonia. Report of time, place, etc. This confirms once again that the traceability of the virus is a complex scientific question. Scientists should conduct international scientific research and cooperation on a global scale to promote understanding of animal host viruses and routes of transmission. The goal is to better prevent future risks and protect countries. The safety and health of people’s lives.
Zhao Lijian said that traceability of the virus is a continuous development process that can involve many countries and places. We hope that all countries will adopt a positive attitude, strengthen cooperation with WHO and others, and promote global traceability. He also affirmed that China will continue to actively participate in global scientific research on virus traceability and transmission routes, and will work with the international community to contribute to global cooperation against viruses and epidemics.
Zeng Guang also stated at the meeting that the epidemic in China can be eliminated at any time. “Because China has the ability to erase zeros, we can only produce calmly after erasing zeros. Many people are susceptible. If you compare the susceptible to dry wood,” one case can be “sparkling fire” without erasing the zeros. Otherwise, the resumption of work and classes may cause the epidemic to repeat itself. “
In general, Zeng Guang believes that “external defense input, internal defense rebound” is the long-term task of the new normal.
