Disease control experts: The virus in the new epidemic is basically the same as the strains circulating in Europe in March and April
The Beijing epidemic ruled out the spread of human epidemic strains or animal viruses in Wuhan
Today (26th), the Chinese Center for Disease Control and Prevention announced the "Progress of Beijing's New Coronavirus Pneumonia Outbreak in June", in which the analysis of the virus source pointed out that the new coronavirus circulating in this outbreak in Beijing is the L genotype European family branch I, the virus The strain is “older” than the current European strain of the same type; this outbreak can rule out the spread of animal virus spillovers to people, as well as the local transmission of strains in Beijing or Wuhan epidemic strains before April this year. The infection mode of the epidemic situation in the new wholesale market is presumed to be direct contact between people or indirect contact through surface contamination.
So, what does it mean that the strain is "older" than the current European strain of the same type? What is the next trend of the Beijing epidemic? We interviewed experts from the Institute of Viral Disease Prevention and Control of the Chinese Center for Disease Control and Prevention.
CCTV reporter Jiang Xiaoping: According to your traceability investigation on the epidemic situation in the new place of Beijing, what is the result of your investigation now?
Wu Guizhen, Chief Expert of Biosafety at the Chinese Center for Disease Control The leakage of the intermediate host is not caused by the virus strains that we have previously popular in our Wuhan. Where is it? After looking at the comparison, we found that it is basically the same as the strains circulating in Europe in March and April.
CCTV reporter Jiang Xiaoping: What does this mean?
Wu Guizhen, Chief Expert of Biosafety of China CDC: This is the problem we need to solve when we trace the source. The first one must first consider the spread of people. Was it caused by an exposure here? We have also detected it in our environment, for example, in its (new development) ditch, such as on the surface of fish, etc., is it environmental pollution? Of course, we may not rule out food contamination. Everyone knows that the epidemic in Europe is also quite serious. Is it because the workers there brought cold pollution to China during cold processing?
China Center for Disease Control: Beijing-related new epidemic-related epidemic situation is basically under control
After the epidemic occurred, governments at all levels in Beijing quickly adopted strong prevention and control measures, and it is expected that the epidemic related to the new wholesale market will be basically controlled. Although several cases of infection have yet to be further investigated, the results of large-scale population testing in Beijing suggest that the infection rate of people unrelated to the new wholesale market is extremely low; in Beijing, surveillance has been strengthened and the prevention and control of social distances have been strengthened. Under the measures, the risk of further spread of the epidemic is low. (General Director CCTV reporter Jiang Xiaoping Shi Yingchun)
