Last updated: 2020-02-07 07:00South China Agricultural University announced on WeChat in the early morning of Friday (7) that according to a recent study, a potential intermediate host that passed on a new coronavirus to humans was pangolin.
According to the announcement, researchers from South China Agricultural University, Lingnan Modern Agricultural Science and Technology Guangdong Laboratory, Professor Shen Yongyi, Professor Xiao Lihua, and other researchers, jointly with Researcher Yang Ruiyu of the Military Medical Research Institute of the PLA Academy of Military Sciences, and Chen Wu Senior Veterinarian of the Guangzhou Zoo Research Department The latest research indicates that pangolin is a potential intermediate host for the new coronavirus, and pointed out that this latest discovery will have great significance for the source control of the new coronavirus.

Zhong Nanshan: Whether there is an intermediate host needs further research
The WHO said earlier that the new coronavirus is likely to originate in bats, but the medical community has never known how it can be transmitted to humans. Zhong Nanshan, an academician of the Chinese Academy of Engineering, recently interviewed the media about the situation of the epidemic prevention and control, saying that the current research basically supports the virus originating from bats, but whether there is an intermediate host still needs to be studied. He also called on all circles to have science on the new coronavirus (2019-nCoV) Awareness and scientific and effective prevention and control to avoid unnecessary panic.
Zhong Nanshan pointed out that the current research shows that the median age of people infected with the new coronavirus is 59 years, and the average incubation period of the virus infection is 5.2 days. Fever is still a typical symptom of the infected people, although there are reports about people with no symptoms. But it is not the main body, and the research results show that the new coronavirus has 79.5% similarity with SARS-CoV virus and 96% similarity with bat-derived coronavirus (CoV), so it basically supports triggering this time The new coronavirus of the outbreak originated from bats.
In addition, research published by researchers at Peking University, Guangxi University of Traditional Chinese Medicine, Ningbo University, and Wuhan Institute of Bioengineering last month in the English academic journal "Journal of Medical Virology" pointed out that the new coronavirus is a recombinant virus with some gene sequences derived from the bat coronatus Virus analysis indicates that snakes are most likely to be animals carrying Wuhan pneumonia virus. Xu Shuchang, chairman of the Scientific Committee for New Discoveries and Animal Infectious Diseases of the Centre for Health Protection, responded that the research was reasoning and was for reference only for the time being. It could not be confirmed. "The reality is not clear."
