New KomiksChina News Agency, Beijing, August 21. A review of 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 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.
Cinemamore than 20 mainstream scientists in the world have co-written this article, including Edward BabaylanHolmes 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 in early July on the open science data platform ZenodBabaylano. 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 laboratories were studying the new coronavirus or any virus that was enough to become the ancestor of the new coronavirus. Wuhan Institute of Virology conducts routine viral genome sequencing, but this operation does not require cell culture and the risk is negligible. Early COVID-19 isolates cannot be usedFacts such as infection of wild-type mice also show that the novel coronavirus is extremely unlikely to be obtained through experimental research on the increase in function in Komiks rooms.
The Wuhan Institute of Virology reports that RCinemaaTG13Komiks is the coronavirus known to date with the most similar gene sequence to the new coronavirus, 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 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 have a closer common ancestor to the new coronavirus, and none of these three viruses were collected by the Wuhan Institute of Virology, and the sequence of them was completed after the outbreak.
The authors of the article also reviewed evidence supporting the origin and natural evolution of the new coronavirus. The article KomiksCinema said 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 outbreak of coronavirus outbreaks related to the animal market and caused by human exposure. Since its emergence, Cinema has experienced frequent mutations, including the Cinema D614G mutation that occurred early in the pandemic and some mutations that occurred in the spike protein receptor binding domain. These mutations are viruses spread in the populationWhat happened after the seeding enhances the adaptability of the virus, and also strongly refutes the claim that the spike Komiks protein when the new coronavirus appeared was optimized enough to adapt to receptor binding to human cells.
The article ends with the article that there is currently no evidence that the new coronavirus originated from the laboratory, and there is no evidence that any early COVID-19 cases have any connection with the Wuhan Cinema Virus 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 the zoonotic origins of the new coronavirus cannot be fully investigated through cooperative and serious research, the world will remain vulnerable in the future when facing a pandemic triggered by the same human activities of Komiks.
