Alina Chan is not saying that the coronavirus must have leaked from a laboratory in China. What you are talking about is what most scientists are willing to discuss publicly: there is no clear evidence for either approach. “I know a lot of people want to have a solid piece of evidence,” said Chan, a postdoctoral researcher at the Broad Institute of MIT. And Harvard University, which specializes in genetic engineering and publicly stated that it needs to investigate the possibility of laboratory leaks.
“It’s more like bread crumbs everywhere, and they don’t always go in one direction. It’s like the whole floor is covered with breadcrumbs.” Chen published an article in Science last month. One of the 18 scientists in the letter called for further investigation of the origin of the virus based on theories of natural occurrence and laboratory spillover. This letter helped initiate a new round of calls to investigate the “laboratory leak hypothesis,” which included a lawsuit involving President Joe Biden and several prominent scientists.
According to interviews with five virologists experienced in microbiology, infectious disease ecology, and virus evolution, if you pay attention to a theory originally promulgated by former President Donald Trump and his followers, the scientific evidence has not changed. In short, it is almost impossible to draw conclusions based on the available scientific evidence, but they point out that the background and circumstances of the origin debate have changed, especially when critics pointed out that China was not fully transparent in the early stages of the pandemic.
This change reflects how some scientists who previously avoided this topic or quickly dismissed it were trapped. They expressed concern among some scientists about publicly discussing the hypothesis of laboratory leaks because they feared that their words would be misunderstood or used. Support racist rhetoric about how the coronavirus originated. Trump contributed to the allegations about the Wuhan Virus Research Institute, which was the research laboratory in the city that reported the first Covid-19 cases and was related to the outbreak, and has repeatedly referred to the pathogen as the “Wuhan Virus “Or “Kung Fu Flu”.
Now more and more scientists are willing to deal with a series of reasonable theories, especially considering China’s opacity on this issue, although many people still warn that considering the idea of laboratory leaks requires clear scientific evidence. But it has not yet become a reality. Viruses A thorny problem is that it is difficult to coordinate various clues. Although most virologists who spoke with reporters said that the coronavirus is likely to have evolved in nature, they agree that it is reasonable to consider this possibility.
The center of these suspicions is the Wuhan Institute of Virology, which was established in the 1950s and was the first research center in China to obtain the highest level of biosafety license. The laboratory biosafety level of the institute is level 4 (called BSL-4, the highest level).
That is, it has the ability to study the world’s most risky infectious pathogens and toxins, which require the most stringent biological protection measures. It was this name and the location of the laboratory in the city where the outbreak was first reported that made the institute one of the first suspects.
