The lab-leaked hypothesis for SARS-CoV-2 says scientists say it should not be denied


Rilman agrees that in the absence of conclusive evidence, the source message should be “we don’t know.” After and after the Lancet speech The next paper Concerning the origin of the SARS-CV-2, written by scientists who concluded that “we don’t believe any kind of laboratory-based scene is admirable,” they themselves became increasingly frustrated with those who claimed they were caught in a spillover scene, although “An amazing lack of information.” Rilman said he felt he had to be pushed back. So he wrote a wide spread Opinion piece The proceedings of the National Academy of Sciences claimed that there was a lab source in several possible situations; Conflicts of interest between all parties to the issue must be expressed and addressed; And uncovering that epidemic was essential to preventing another epidemic. Attempts to investigate the origins, he writes, “have been well received in politics, supported by conjecture and conviction, and contain incomplete information.”

The first media call came after Fox News’ Lara Ingraham commented, Rilman said. He declined the interview.


When asked why Daszak and others pressed so strongly against the possibility of lab leaks, Rilman said they wanted to perceive their work as dangerous to mankind. For example, with the help of so-called “function gain” experiments, scientists genetically lead viruses to investigate their evolution – sometimes in ways that could increase virulence or infection. This type of research could reveal targets for drugs and vaccines for viral diseases, including Covid-19, and studies at the Wuhan Institute of Virology used to show that certain bat coronaviruses were only a few changes away from being able to bind to human AC2. A 2015 paper Nature Medicine notes that “the potential for future outbreaks needs to be weighed against the risk of creating more dangerous pathogens.”

Rilman suggests that among those trying to suppress lab-release speculation, there may be much more protection for themselves and their peers “before the opportunity to hear really important questions.” “And scientists collaborate with Chinese researchers. If they say anything other than ‘this threat comes from nature,’ they may be concerned about their work relationship.”

Other scientists say that opposition to the lab-leaked hypothesis was further grounded by the general belief that the stork-cove-2 could be deliberately engineered. “It simply came to our notice then. Asked if the virus escaped after it developed naturally, he said it was “more difficult to rule or overturn the verdict”.

In an email message last week, Rilman added that the question could never be fully settled. “From a natural-spillover angle, it requires a reliable communication between a proven naturally infected host species (e.g., a bat) and a human or a human that can be shown with reliable, definite time and place details because it has been infected as a result of an encounter, Before the known human case, “Rilman said,” and then others have been shown to have cut the infection. “As for the lab-leaked situation, there needs to be” conclusive evidence of the virus’s possession before the first case and a possible escape mechanism in the human body – all of which are less likely over time, “he said, adding that” the potential instant Parental traces will help understand the recent genomic / evolutionary history of the virus, “he added,” but not how history happened. “

As it stands now, epidemic preparations face two simultaneous fronts. On the one hand, the world has seen three outbreaks in the last 20 years, including stork, chikungunya, H1N1, respiratory syndrome in the Middle East, several Ebola outbreaks, norovirus, Zika and now stork-covi-2. . Speaking about the coronavirus, Ralph Barrick, an epidemiologist at Chapel Hill University in North Carolina, said it was hard to imagine “bats” not having “forms” with the Mars rate, adding that “transmissibility is much more efficient.” Emphasizes that genetic research, including viruses, is essential to stay ahead of the threat.

However, according to Richard Ebright, a molecular biologist at Ritgers University, the risk of lab-release is also increasing. He says the risks are higher than the number of biopins and potential epidemic pathogens operating (more than 1,500 worldwide in 2010), many of them like Uhan Lab, located in a city near international airports. “The most dramatic expansion in China in the last four years has been in response to the arms-style response to the expansion of biodefense in the United States, Europe and Japan,” Ebright wrote in an email to Uberk. “China has launched two new BSL-4 facilities in Wuhan and Harbin in the last four years,” he added, “and announced plans for hundreds of new BSL-3 and BSL-4 lab facilities.”

Meanwhile, squabbles continue over the origins of the Stork-Cavi-2, some of which are heated. During a recent exchange of views on Twitter, Chan was compared to a Kyun supporter and rebel group. A few months ago, he tweeted about research integrity issues and said that if the actions of scientists and journal editors obscure the source of the virus, those individuals could be the cause of millions of deaths. (Chan deleted the tweets he said he regretted posting.)

“Moods are high,” Nielsen said, making it difficult for skilled scientists to have any serious discussions.

Petrovixi in Australia says he is trying to stay on top of the fight. She says she was warned to avoid talking publicly about the results of her modeling. “A lot of people advised us, ‘If this is good science, don’t talk about it. This will have a negative effect on the development of your vaccine. You will be attacked; They will try to discredit you. “It simply came to our notice then. Last year, in the source controversy, his team became the first to receive vaccines in human clinical trials for Covid-19 in the Southern Hemisphere.

“If we reach a stage where all science is politicized and no one thinks about the truth and is only politically correct,” he said, “we can give up and shut down science as well.”

Update: Correcting the story suggests that multiple cave workers who came in contact with the bat face in Yunnan Province may have died.
