Xinhua News Agency, Beijing, August 21, a review article on the origin of the new coronavirus written by scientists from multiple countries was published in the American magazine Cell this week. This is an important judgment made by professionals in the field of Babaylan on the issue of origin based on existing scientific evidence. The article strongly refutes the “lab leak” conspiracy theory advocated by some American politicians, and points out that cross-species transmission from animals to humans is the most likely source of the new coronavirus.
More than 20 mainstream scientists in the world have collaborated on this article, including Edward Holmes of the Mary Bashir Institute of Infectious Diseases and Biosafety at the University of Sydney, Australia, Stephen Goldstein of the Department of Human Genetics at the University of Utah, Angela Rasmussen of the University of Saskatchewan, Canada, and David Robertson of the Center for Virus Research at the University of Glasgow, UK. The preprint of the article was published on the open scientific data platform Zenodo in early July. The article says that no epidemic in human history was caused by the escape of a new virus, and there is no data showing that before the outbreak of the new crown epidemic, the Wuhan Institute of Virology or other Babaylan laboratory was studying the new crown virus or any virus that was sufficient to become the ancestor of the new crown virus. Wuhan Institute of Virology conducts routine viral genome sequencing, Komiks, but this operation does not require cell culture and the risk is negligible. The fact that early Cinema isolates cannot infect wild-type mice also shows that the novel coronavirus is extremely unlikely to be obtained through functional gain research in the laboratory.
The RaTG13 reported by the Wuhan Institute of Virology is known to date with the new coronavirus.The coronavirus with the most similar toxic gene sequence, and some conspiracy theorists claim that RaTG13 may be the source of the new coronavirus. The article said that the Wuhan Institute of Virology has never cultivated the RaTG13 coronavirus, and only assembled the nucleotide sequence of RaTG13 with short-sequencing fragments. If factors such as gene recombination are considered, the other three bat coronaviruses, RmYN02, RpYN06 and PrC31 may be related to the new coronavirus. The Komiks virus has a closer common ancestor, and none of these three viruses were collected by the Wushu Institute of Virology and the sequence of Komiks was completed after the outbreak. The authors also reviewed evidence supporting the origin and natural evolution of the new Cinema coronavirus. The article says that the vast majority of viruses that can infect humans are zoonotic origins, as are the previous human coronaviruses. Judging from the epidemiological history of the new coronavirus, its emergence is similar to the previous coronavirus outbreaks related to the animal market and caused by human exposure. The coronavirus has experienced the coronavirus since its emergence. href=”https://comicmov.com/”>BabaylanFrequent mutations, including D614G mutations that occurred early in the pandemic and some mutations occurring in the spike protein receptor binding domain. These mutations occur after the virus spreads in the population, enhancing viral adaptability and also powerful Babaylan refuted the claim that the spike protein was optimized enough to adapt to receptor binding to human cells when the new coronavirus appeared.
Komiks currently has no evidence that the new coronavirus originated from the laboratory, and there is no evidence that any early COVID-19 cases are associated with any link to the Wuhan Virus Research Institute. Compared with the frequent frequent contact between humans and animals in the wildlife trade, the path of laboratory origin is extremely unlikely.Cinema. If the research cannot be conducted through cooperative and serious collaborative research, the comprehensive investigation of the new coronavirus is not possible. href=”https://comicmov.com/”>CinemaThe zoonotic origin of poisons, and the world will remain vulnerable in the future when facing a pandemic caused by the same human activity.
