World health Organization expert group traces source of new coronavirus in Wuhan, work has reached the end. The Chinese side and the WHO expert team held a joint press conference in Wuhan on Tuesday (9). Liang Wannian, head of the Chinese side of the joint expert mission, said there is no evidence that the outbreak spread in Wuhan before December 2019. The WHO expert team said it was “extremely unlikely” that the virus came from the Wuhan laboratory.
Liang Wannian, head of the Chinese side of the joint expert mission, said there was no evidence that the outbreak had spread in Wuhan before December 2019. He said that although bats and pangolins were either the hosts of the outbreak, the virus found in them was not similar enough to be a direct ancestor of the new coronavirus, or there were other species that were potential hosts.
Liang Wannian also said that in the early stages of the outbreak, Wuhan’s South China Seafood Market was one of the outbreak points of the virus, but there seems to be transmission elsewhere in Wuhan, and it is impossible to determine how the virus spread to the South China Seafood Market.
But one of the members of the WHO expert group Dazak earlier interviewed by Bloomberg News revealed that the trip found important clues about the role played by the wholesale seafood market in South China, the outbreak of the Epidemic. He said that although the wholesale market has been closed after the emergence of confirmed cases, thorough cleaning and disinfection, but the stall vendors left behind equipment and utensils and other evidence, so that the expert group can study, I believe it can come to very valuable conclusions, but he did not talk about the details.
China and the WHO expert group earlier visited the Baishazhou Trade Market, South China Seafood Market, Hubei Provincial Center for Disease Control and Prevention, Wuhan City Center for Disease Control and Prevention, Hubei Animal Disease Prevention and Control Center, Wuhan Institute of Virus, Chinese Academy of Sciences and other institutions to trace the source of the new coronavirus.
