According to the Securities Times. The latest conclusions of the source of the new outbreak virus through swab testing: from cold chain imported food

According to news from the Beijing Evening News on the evening of the 27th, Tsinghua University, Beijing Centers for Disease Control and Prevention, Institute of Pathogen Biology, Chinese Academy of Medical Sciences, Peking University, and Beijing Institute of Genomics, Chinese Academy of Sciences recently jointly published an article in the “National Science Review” and analyzed related cases. Nucleic acid sequencing and viral genome sequences of samples from, environment and food, combined with comprehensive epidemiological investigations and big data analysis, the researchers revealed that the source of the virus in the epidemic is most likely to be imported cold chain foods in high-risk areas overseas. It is proposed that cold chain transportation may be a new way for the spread of the new coronavirus.

Prior to this, the Qingdao epidemic prevention and control work found a sufficient chain of evidence for the first time in the world through swab testing, indicating that the new coronavirus can be transmitted from person to person and can survive for a long time under freezing conditions.

Wu Zunyou: The new outbreak is strange, not from Beijing

Wu Zunyou, chief epidemiologist of the China Centers for Disease Control and Prevention, also made a similar view when interviewed by CCTV News. Regarding the source of the Beijing epidemic, Wu Zunyou believes that “the occurrence of such an epidemic in a new place is very strange. It did not originate in Beijing. It must be someone or something outside of Beijing that brought the virus to the new place.”

Wu Zunyou also said that sporadic cases, including clusters of cases, should be said that as long as the global epidemic is not fully controlled, they may happen anywhere at any time. It should be said that the epidemic in Beijing has been reported to other places in China and to other places in the world. One is to sound the alarm, and the second is to provide a very good response experience. The most important thing is to compete for time and speed with the virus in the first place. Before it spreads, contain the virus in the cradle of proliferation and prevent it from spreading on a larger scale. Many new technologies have been used in this, and various departments work closely together to be able to locate the source in the shortest time, which is very remarkable. Such a move is also worth learning from other places. In the unlikely event of a new epidemic, it can be discovered at the first time and measures can be taken as soon as possible.
