World Health OrganizationAfter the (WHO) expert group went to China to conduct a joint investigation in Wuhan and China, they announced the findings and results of the investigation on the origin of the new coronavirus, the South China seafood market, the role of bats, and the “leakage of the virus” of the Wuhan Institute of Virology.
The China-WHO Joint Expert Group on the Traceability of the Novel Coronavirus held a press conference on February 2. The three experts attended were Liang Wannian, the former Director of the System Reform Department of the National Health Commission of China and the current Professor of Public Health at Tsinghua University. Peter Ben Ambarek, a Danish scientist from the World Health Organization
Ben Enbarek) and Dutch virologist Marion Koopmans (Marion Koopmans).
The press conference announced the conclusions of the joint investigation on issues of concern to the outside world:
Wuhan South China Seafood Market
Liang Wannian, the Chinese leader of the joint expert inspection team, said that according to the cases of more than 200 hospitals in Wuhan, there was no unrecognized new coronavirus cycle in Wuhan in the second half of 2019.
Liang Wannian said: In December 2019, a certain scale of infection occurred in the population of Wuhan. Many early cases were related to the South China Seafood Market, which can only prove that the market is one of the spreading points of the virus.Based on current data, it is impossible to determine how the new coronavirus was introduced to the South China seafood market.
Experts at the press conference also said that the initial infection cases were partly related to the South China Seafood Market, partly to other markets, and partly to any market.
Bats and viruses
Regarding the argument that bats may be the direct origin of the virus, the expert group stated that the virus carried by bats is not the direct ancestor of the new coronavirus.
Liang Wannian said that the coronaviruses found in bats and pangolins are believed to be closely related to the new coronavirus, but not enough to make them the direct ancestor of the new coronavirus.
He said: A virus that can cause a global pandemic must be highly adaptable to the human environment.This ability may be acquired by accident, or it may gradually evolve, but each step benefits from natural selection.
Peter Ben Ambarek said that relevant evidence suggests that the virus may come from a natural host. "But Wuhan is not a place where bats gather in large numbers. Therefore, the epidemic in Wuhan is unlikely to be transmitted from bats to humans at the beginning, but may be transmitted by other animals."
Wuhan Institute of Virology
After the outbreak of the new crown virus, the Wuhan Institute of Virology of the Chinese Academy of Sciences became the focus of outside attention. It is believed that the new crown virus leaked by the Institute of Virus caused the initial outbreak of the epidemic.
Peter Ben Ambarek said at a press conference that according to the investigations conducted by the World Health Organization’s expert team at the Wuhan Institute of Virology and exchanges with scientific researchers, it was concluded that the possibility that the virus came from the institute was “extremely remote”
unlikely), and will not further investigate this in the future.
Chinese expert Liang Wannian also added that the Wuhan Institute of Virology had no new coronavirus before the outbreak, so there was no possibility of the virus leaking.
WHO's investigation in China
Before the World Health Organization's investigation in China, the outside world has been calling for China to open up to the international community to investigate the origin of the virus.The joint research team this time includes 17 experts from China and 17 international experts from the World Health Organization and the World Organisation for Animal Health.
The joint expert group consisted of three teams and carried out a 28-day virus traceability work in Wuhan, and visited Baishazhou Trade Market, South China Seafood Market, Hubei Provincial Center for Disease Control and Prevention, Wuhan Center for Disease Control and Prevention, and Hubei Province Animal Diseases Prevention and Control Center, Wuhan Institute of Virology, Chinese Academy of Sciences and other institutions.
At the press conference, a reporter asked if there were reports of virus cases in other parts of the world before the outbreak of the Wuhan epidemic, whether this was related to the emergence of the new coronavirus in Wuhan.
Marianne Koopmans replied that this also requires a genetic comparison between the virus that appeared in Wuhan and the virus that appeared in other places to draw a conclusion.
Wuhan, China is the first city in the world to adopt lockdown measures to prevent the spread of the new crown virus.The epidemic caused by the new crown virus in the world is still far-reaching, and there are still many countries that have not escaped the dilemma caused by the epidemic.
The latest conclusions released by the World Health Organization and China’s joint investigation team can eliminate the outside world’s “opaqueness”, “concealment” and “suppression of whistleblowers” regarding the Chinese government’s handling of the epidemic
Waiting for criticism remains to be seen.
Peter Ben Ambarek said that the World Health Organization will publish the conclusions and recommendations of this investigation, and more experts going to China will also accept media inquiries and interviews.Regarding the emergence of the new coronavirus in the food freezing chain, he said that this will be a problem that needs to be studied.
