Xinhua News Agency, Beijing, August 21 Cinema A review article on the origin of the new coronavirus written by scientists from multiple countries was published this week in the US Journal of Cell. This is an important judgment made by professionals in this field on the issue of traceability based on existing scientific evidence. The article strongly refuted the “lab leak” conspiracy theory that some American politicians praised, and pointed 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 written this article, including Edward Holmes of the Marie Bashir Institute of Infectious Diseases and Biosafety, University of Cinema, Australia, Stephen, Department of Human Genetics, University of Utah, Komiks, Goldstein, University of Saskatchewan, Canada, Angela Rasmussen, Vaccine and Infectious Diseases Organization, University of Saskatchewan, Canada, David, University of Virus Research, University of Glasgow, UK href=”https://comicmov.com/”>Komiks Robertson et al. The preprint of the article was published in early July on the open scientific data platform ZenKomiksodo. The article said that no epidemic in human history was triggered by the escape of a new virus, and there was no data showing that before the outbreak of the new coronavirus, the Wuhan Institute of Virology or other laboratories were studying the new coronavirus or any virus that was enough to become the ancestor of the new coronavirus. The Wuhan Institute of Virology conducts routine viral genome sequencing, but this operation does not require cell culture and the risk is negligible. Early COVID-19The fact that the virus isolates cannot infect wild-type mice also shows that the novel coronavirus is extremely unlikely to be obtained through functional gain studies in the laboratory. The RKomiksaTG13 reported by the Wuhan Institute of Virology is the most similar coronavirus to the gene sequence of the new coronavirus so far, and some conspiracy theorists claim that RaTG13 may be the source of the new coronavirus. The article stated that the Wuhan Institute of Virology has never cultivated RBabaylan The nucleotide sequence of KomiksaTG13 coronavirus is assembled with short sequencing fragments. If factors such as gene recombination are considered, the other three bat coronaviruses, RmYN02, RpYN06, and PrC31, may have a closer common ancestor to the new coronavirus, and none of these three viruses were collected by the Wuhan Institute of Virology, and they were sequenced only after the outbreak of the outbreak.
The authors of the article also reviewed the zoonotic origin of the new coronavirus. Evidence from Cinema and natural evolution. The article says that most viruses that can infect humans are zoonotic origins, as are the previous human coronaviruses. Judging from the epidemiological history of the new coronavirus, its appearance is similar to the previous coronavirus outbreaks related to the animal market and caused by human exposure. The new coronavirus has experienced frequent occurrences since its emergence as Komiks Cinematraditional mutations, including D614G mutations that appeared early in the pandemic and some mutations occurring in the receptor binding domain of the spike protein. These mutations occur after the virus spreads in the population, enhancing the adaptability of the virus and also strongly refutes that the spike protein was optimized to be suitable when the new coronavirus appeared.There should be a statement about receptor binding with human cells.
The article ends with the article that there is currently no evidence that the new coronavirus is from the laboratory and there is no evidence that any early Cinema COVID-19 cases have any connection with the Wuhan Virology Research Institute. Compared with the frequent frequent contact between humans and animals that often occur in the wildlife trade, this path of laboratory sources is extremely unlikely. If people who cannot fully investigate the origins of the new coronavirus through cooperative and serious research, the world will remain vulnerable in the future when facing a pandemic caused by the same human activity.
