Original Caption: “Bats” Get the Snow “? New Major Release of Crown Traceability! Lab is highly unlikely to leak viruses, and minks and cats can be hosts too! internauts …
One year later, the bat appears to be an “injustice”!
According to major media reports, on the afternoon of February 9, the China-WHO Joint Expert Group on the Traceability of New Coronavirus held a press conference in Wuhan. At the meeting, Liang Wannian, Chinese leader of the joint expert inspection team, stated that there was no unrecognized new coronavirus cycle in Wuhan in the second half of 2019. During the same period, more than 4,500 early samples were reviewed in Hubei and no relevant findings were found. At the same time, there is no evidence that the virus has spread in Wuhan before December 2019. Peter, the foreign leader of the joint expert group, said it is extremely unlikely that the virus from the laboratory was leaked, and there will be no investigation. about this in the future.
At the same time, Liang Wannian also stated that coronaviruses found in bats and pangolins are believed to be closely related to the new coronavirus, suggesting that they may be the host of the new coronavirus. But so far, this correlation is not enough to determine that the viruses carried by the two animals become direct ancestors of the new coronavirus.

Laboratory leaks are highly unlikely to cause an epidemic
On February 9, the China-WHO Joint Expert Group on the Traceability of New Coronavirus held a press conference.
According to China Youth Network, at this press conference, foreign expert Peter listed four hypotheses about the spread of the new corona virus to people. Among them, the introduction of viruses into humans through an intermediate host, that is, first infecting animals that are closest to humans, and then infecting humans, this route is the most likely. Also, it is more likely to infect people through food in the cold chain.
He said it is extremely unlikely that the lab virus was leaked and will not be studied in the future. Previously, the West once believed that the new corona virus originated from a laboratory virus leak, and some conspiracy theories were born as a result.
On January 14, members of the World Health Organization’s group of virus traceability experts arrived in Wuhan, and the isolation ended on January 28. Subsequently, the WHO expert team visited the South China Seafood Market, the Center for Disease Control, the Wuhan Institute of Virology and other places to conduct on-site inspections. Liang Wannian, Chinese leader of the joint expert inspection team, told the meeting that the joint research team includes 17 experts from China and 17 national experts from the World Health Organization and the World Organization for Animal Health. He presented that the joint expert group consisted of three joint investigation teams, which carried out 28-day virus traceability work in Wuhan.
There is no evidence that it spread in Wuhan before December 2019.
Liang Wannian, Chinese leader of the joint expert inspection team, said there was no unrecognized new coronavirus cycle in Wuhan in the second half of 2019. During the same period, more than 4,500 early samples were reviewed in Hubei and no found relevant findings.
Presenting the results of the molecular epidemiology traceability study, he said that there is no evidence that the epidemic has spread in Wuhan before December 2019. The research he mentioned includes the analysis of samples kept in the previous hospital, the analysis of medical records, the study of fluctuations in the sales of fever drugs and the study of death data from respiratory diseases.
In December 2019, a certain scale of infection occurred in the Wuhan population. Many of the early cases were related to the South China seafood market. This can only prove that the market is one of the spreading points of the virus, but other areas of Wuhan may have spread. Based on current data, it is impossible to determine how the new coronavirus entered the South China seafood market.
In this regard, some netizens sighed: “Don’t blame our South China seafood market anymore, we are just one of the broadcast points!”
Peter, a member of the WHO Expert Group on Traceability of New Coronaviruses, said we believe that the introduction of viruses into humans via intermediate hosts is the most likely path, requiring us to carry out more specific and targeted research. in this area in the future.
The virus carried by bats is not the direct ancestor of the new coronavirus
Integrating news from Beijing Youth Daily and Jiemian News, Liang Wannian presented the results of molecular epidemiology traceability research and said that viruses that can cause a global pandemic must have the ability to survive highly adapted to the human environment. This ability can be acquired accidentally or it can evolve gradually, but each step benefits from natural selection.
He said that coronaviruses found in bats and pangolins are believed to be closely related to the new coronavirus, suggesting that they may be the host for the new coronavirus. But so far, this association is not enough for the viruses carried by the two previous animals to become direct ancestors of the new coronavirus. Animals like mink and cats can also be potential hosts.
Some netizens said: Can you still have cats? When will pet vaccines become popular?
The head of the WHO expert team, Peter, said relevant evidence suggests that the virus may have come from a natural host. But Wuhan is not a place where bats gather in large numbers, so the epidemic in Wuhan is unlikely to be transmitted from bats to humans at first, but it can be transmitted by other animals.
Peter said that the genetic sequence of the new coronavirus sampled in Wuhan is very similar to the new coronavirus in bats. In the future, more research will be conducted in the supply chain of various parts of the country and imported food.
WHO’s traceability work requires more reliable case testing materials. Potential research materials include blood samples from blood banks at an early stage, and in-depth studies on early cases are required. In addition, it also includes research of animal species, especially bats, but not only surveys in China, this work will cover the world.
WHO: discussing cooperation with Chinese vaccine manufacturers
According to CCTV News, on February 8 local time, the WHO held a routine press conference for new corona pneumonia. WHO chief scientist Sumia Swaminatan said China has a variety of new corona vaccines in development. WHO communicates with Chinese vaccine developers. WHO is currently evaluating vaccine materials provided by China National Pharmaceutical Group and China Kexing Company, and a team is also investigating related vaccine production facilities in China.
Sumia Swaminathan said: “We are now very encouraged to know that Chinese vaccine manufacturers are ready to provide 10 million doses of vaccine for the ‘New Coronary Pneumonia Vaccine Implementation Plan’ in the coming months.” Based on the WHO Organize standards, such as emergency use lists, and Chinese vaccine manufacturers will discuss specific terms with WHO on the “New Coronary Pneumonia Vaccine Implementation Plan”.
Zhang Wenhong’s last voice: stand up for yourself this year
On February 8, Zhang Wenhong, director of the Department of Infectious Diseases of Huashan Hospital affiliated with Fudan University, gave suggestions for citizens to spend the peaceful Spring Festival in an interview with Shanghai TV.
He said last year he proposed “fire prevention, theft prevention and peer prevention.” The epidemic prevention situation this year is to “defend yourself”, and at the same time, spend more time with the family than with “others”.
Zhang Wenhong said that at the Spring Festival last year, the epidemic had only just started to spread. At that time, the detection ability was not as strong as it is now. At the time, he proposed “fire prevention, theft and colleague prevention.” the crowd is dense.
The situation of prevention of the epidemic this year is different, it is to protect itself from the “I”. In most cases this year, the environment is safe. However, once there are a few individual cases, it is possible for a spark to ignite in a fire.
Therefore, we must “defend ourselves” this year, we must ensure that our protection work is at home and in place, that is, masks, hand washing and not meetings.
