The outbreak of new coronavirus (2019-nCoV) pneumonia continues, and experts from the World Health Organization point out that the virus may originate from bats, especially Rhinolophus. Xiaobo Tao, a professor at South China University of Technology, published a report entitled "Possibility of Source of New Coronavirus (2019-nCoV)", stating that chrysanthemum bats mainly live in Yunnan Province and Zhejiang Province, and are far from the South China seafood market, which is said to be the source of the outbreak. More than 900 kilometers. The Wuhan Centers for Disease Control, which is less than 300 meters away from the market, once captured bats to study coronavirus, and even researchers were splashed with blood and urine from bats. Researchers had to isolate themselves for 14 days.

The report suspected that the relevant animal experimental samples and contaminated waste would be pathogens, but the report was not published in authoritative academic journals, but only published on scientific paper sharing websites. The paper has not been found. "Hong Kong 01" reporter wanted to call Xiao Botao for verification, but the other party did not listen to the phone. Earlier, some people suspected that the outbreak was related to another laboratory in Wuhan and the Wuhan Institute of Virology of the Chinese Academy of Sciences, but officials have repeatedly denied it.

Chrysanthemum bats mainly live in Yunnan, Zhejiang and Wuhan

The author of this report is Xiao Botao, a professor at the School of Biological Science and Engineering of South China University of Technology. He has worked at Harvard Medical School, and has collaborated with Northwestern University in the United States. He has won several National Natural Science Funds. The report ended on February 6, referring to the sequencing of the novel coronavirus genes, and found that 96% and 89% are similar to the coronavirus (CoV ZC45) found in chrysanthemum bats, but the pathogen and how to pass it to humans must be studied. The report cited a medical journal study stating that 27 of the 41 people infected in Wuhan were associated with South China Seafood City, and 33 of the 585 samples collected in South China Seafood City detected the new coronavirus.

However, bats carrying CoV ZC45 were first found in Yunnan Province and Zhejiang Province, more than 900 kilometers away from South China Seafood City. In addition, bats usually live in the wild and the population is dense. The probability of bats flying there is "very low" . Although the South China Seafood Market sells game, it does not sell bats.

Laboratory holds nearly 600 bat experts who had accidents

The report mentions the possibility of other ways, pointing out that there are two laboratories in Wuhan, in addition to the Wuhan Institute of Virology, Chinese Academy of Sciences, P4 level 30 kilometers away from the South China Seafood Market, and the Wuhan Center for Disease Control and Prevention, only 280 meters away from the seafood market WHCDC), which holds animals for research purposes including collecting and distinguishing pathogens.

The report cited past official sources that the Wuhan Center for Disease Control and Prevention had captured 155 bats from Hubei Province, including the chrysanthemum, and 450 bats from Zhejiang Province. However, the researcher responsible for the study mentioned two accidents in media interviews in 2017 and 2019, including that he had been attacked by a bat, and the blood of the bat splashed on his skin, so he isolated himself for 14 days. The bat urinates and must be isolated; he once made a live tick on the bat.

The first confirmed doctors in a nearby hospital

The relevant research method of WHCDC is to extract DNA and RNA from these animals for sequencing by surgery. The relevant samples and contaminated garbage will be pathogens. The implementation room is only 280 meters away from South China Seafood City and also near Xiehe Hospital, which has the first Doctors confirmed for new coronavirus. The report argues that, although firm evidence is needed in the future, it is believed that the virus leaked around and infected the original patients.

As for the Wuhan Institute of Virology, Chinese Academy of Sciences, 12 kilometers away from South China Seafood City, it has been tracking SARS-CoV virus research in 2003, such as using reverse genetics methods. Therefore, "direct speculation" means that the laboratory may have leaked SARS-CoV or its derivatives.

Summary quotes suggest that high-risk laboratories should stay away from humans

The report concluded that some people are concerned about the evolution of the 2019-nCoV coronavirus. In addition to natural recombination and the origin of intermediate hosts, lethal coronavirus may also come from laboratories in Wuhan. The safety level of high-risk biological laboratories may need to be strengthened. Regulations should be adopted to keep laboratories away from city centers and other densely populated areas.

This report was published on the academic sharing website Research Gate on February 6. It was not published in an authoritative academic journal, but Research Gate has not been able to find the article. "Hong Kong 01" reporter called Xiao Botao for inquiry, but the other party did not answer the phone.

Wuhan closed the city, public transportation was stopped, tens of thousands of people were infected, and people in the city were frightened. Residents wore masks when they went out. Some people went to the supermarket to protect themselves with plastic bags. (Chinatopix / Associated Press)

WHO: No intermediate host found

Officials from the World Health Organization said on February 11 that after the Chinese government's health department published the viral gene sequencing, scientists found that the new coronavirus has the opportunity to come from bats and then transferred to intermediate hosts to infect humans. However, it is not yet known which animal the intermediate host is. Sylvie Briand, head of the infectious disease hazard management department, attended a press conference at the Geneva headquarters and said that after arriving at the South China seafood market in the hardest hit area of ​​Wuhan, scientists did not find a large number of bats, indicating that further research is needed.

Researcher of the Institute of Virus `` life guarantee '' denies laboratory leak

There have always been doubts that the epidemic is related to laboratories in the Mainland, including the laboratory of the Wuhan Institute of Virology, Chinese Academy of Sciences, which is 30 kilometers away from the South China Seafood Market and the highest national level (P4).

Shi Zhengli, a researcher at the Wuhan Institute of Virology of the Chinese Academy of Sciences, said on February 2 that "life guarantees" were not leaked by the laboratory, referring to "the new type of coronavirus as a punishment of uncivilized living habits of human beings by nature", which means that it is related to food game. Peter Daszak, Shi Zhengli's long-time partner and disease ecologist at the US Non-Profit Organization Environmental Ecology Health Alliance, also said that the laboratory leak was "conspiracy theory."
