New crown joint traceability press conference, a great amount of information——

Liang Wannian, the Chinese leader of the joint expert investigation group, pointed out at a press conference that there was not enough evidence to show that the new coronavirus had spread in Wuhan before December 2019

.

In Beijing, Wuhan did not find sufficient evidence that there was epidemic transmission in the city before December 2019, according to the report of February 9th

Beijing, February 9 (AFP) – a World Health Organization expert said on February 9 that it is “most likely” that the new coronavirus will spread from the first animal to the second and then infect humans

.

When introducing the results of the traceability study of molecular epidemiology, Liang Wannian, the Chinese leader of the joint expert investigation group, said that the virus that can lead to global pandemic must have a high ability to adapt to the human environment

.

Video source: Xinhua news agency in addition, he said that transmission from animals is possible, but this animal “remains to be confirmed.”

.

Joint traceability study: the virus carried by bats is not the direct ancestor of neocoronavirus

.

Liang Wannian said that a certain scale of infection occurred in Wuhan in December 2019, and many early cases are related to the South China seafood market, which can only prove that the market is one of the transmission points of the virus, but there may be transmission in other regions of Wuhan

.

This ability may be acquired by accident or gradually evolved, but each step benefits from natural selection

.

Foreign expert group leader: Wuhan COVID-19 is unlikely to be from bat group leader Peter, the relevant evidence suggests that the virus may come from the natural host

.

China – WHO New Coronavirus traceability research joint expert group held a news conference

.

Liang Wannian believed that it was “unlikely” that the virus would spread in the two months, and said that the early spread of the new coronavirus occurred a few weeks before the first cases were found, which is probably the reason why no cases were found outside China

.

China who expert group: the joint study will lay the foundation for the traceability of the new crown in other countries

.

Liang Wannian, the Chinese leader of the joint expert investigation group, said at the annual meeting that the joint research belongs to the Chinese part of the global traceability research on SARS and new coronavirus

.

Recently, the China who expert group visited Baishazhou trade market, South China seafood market, Hubei Center for Disease Control and prevention, Wuhan Center for Disease Control and prevention, Hubei Center for animal disease control and Prevention, Wuhan Institute of Virology, Chinese Academy of Sciences, etc

.

The report also said that the World Health Organization had warned that patience was needed before a possible answer could be found

.

In Wuhan, we found the earliest case on December 8, 2019, while the first confirmed case in South China seafood market was December 12, 2019

.

However, Wuhan is not a large gathering place for bats, so the epidemic in Wuhan is unlikely to be transmitted from bats to people at the beginning, and it may be transmitted by other animals

.

Liang Wannian: many early cases in Wuhan are related to the South China seafood market, which can only prove that the market is one of the transmission points of the virus

.

From the current epidemiological survey, there is no relationship between the two cases

.

China’s novel coronavirus pneumonia coping group, Liang Wannian, said in February 9th that the spread of COVID-19 in other places may be earlier than in Wuhan

.

The joint expert group conducted a scientific evaluation on the possibility of the new coronavirus being directly transmitted from the natural host and introduced into the population through cold chain food, intermediate host, laboratory and other four ways (the evaluation conclusion is divided into “extremely unlikely”, “impossible”, “possible”, “relatively likely” and “relatively likely” It is considered that the new coronavirus is “more likely” to be introduced into the population through the intermediate host, or “likely” to be directly transmitted or introduced into the population through cold chain food, “highly unlikely” to be introduced into the population through the laboratory

.

Liang Wannian: the South China seafood market may not be the first place where the epidemic occurred

.

China’s novel coronavirus pneumonia was investigated in China by an international group of experts from China and who, according to Agence France-Presse Wuhan February 9th

.

Minks, cats and other animals may also be potential hosts

.

Liang Wannian, Chinese leader of the joint expert investigation group, said that the South China seafood market may not be the first place where the epidemic occurred in Wuhan

.

Liang Wannian: no unidentified new coronavirus circulation in the second half of 2019 in Wuhan

.

Joint expert group: the new coronavirus may be directly transmitted or introduced into the population through cold chain food

.

They announced on February 9 that there was no evidence that the new coronavirus had existed in Wuhan for a long time before it was found, and that the source of the disease was not confirmed

.

The research report based on the research foundation of global and Chinese past scientists will lay the foundation for the virus traceability work in other countries and regions

.

But so far, this association is not enough to confirm that the viruses carried by the above two animals become the direct ancestors of the new coronavirus

.

Liang Wannian, the Chinese leader of the joint expert group, said in introducing the results of the traceability study on molecular epidemiology that there is no evidence that the epidemic will spread in Wuhan before December 2019

.

However, Peter ambarek, who expert group leader, said at a news conference that this path needs to be “more specific and targeted.”

.

Joint traceability study: minks and cats may also be the hosts of the new coronavirus

.

He said that the coronavirus found in bats and pangolins is considered to be closely related to the new coronavirus, suggesting that they may be the host of the new coronavirus

.

Reported that he also said that the new coronavirus from the laboratory leak hypothesis “highly unlikely.”

.

According to the current data, it is impossible to determine how the new coronavirus was introduced into the seafood market in South China

.

Liang Wannian, the Chinese leader of the joint expert investigation group, said in introducing the results of the molecular epidemiology traceability study that the coronavirus found in bats and pangolins is not enough to confirm that the virus carried by the above two animals has become the direct ancestor of the new coronavirus
