The debate over the origins of covid-19 is reaching fever pitch. on monday The Wall Street Journal published an article describing reports published within the US government. last year The virus research laboratory in Wuhan, China, was found to be the source of the pandemic. at the same time Nothing seems to have changed much when it comes to actual evidence about the origin of the virus.
to follow WSJThe report was released by Lawrence Livermore National Laboratory, a federal research center in California, in May 2020. It was later referenced in assessments conducted by the State Department near the end of Trump’s presidency. The report looked at the genetics of the coronavirus known as SARS-CoV-2 and concluded that “the hypothesis claiming the virus leaked from a Chinese laboratory in Wuhan” is plausible and deserves further investigation. according to the article Lawrence Livermore National LabHowever, it did not respond to a request for comment from the WSJ.
Monday’s WSJ reporting should not be confused with the problematic part from the op-ed desk. published On Sunday, titled: “The Science Suggests a Wuhan Lab Leak” in the comments, Steven Quay and Richard Muller argue that SARS-CoV-2 has a “genomic footprint never seen in the natural coronavirus.” Quay and Muller have scientific training bThe specialty of the Utkey appear for breast cancer research And Muller previously claimed a reputation as a physicist and later denied climate change. changed his thoughts.
SOther scientists have criticized the op-ed hypothesis that SARS-CoV-2 has a unique feature known as a furin cleavage site, which cannot occur in a naturally evolved coronavirus. spiral worldYes! Evolutionary biologist and journalist trained for Nature News Amy Maxmen said the one bit of genetic code referenced in the WSJ op-ed is called the CGG codon. “is rare in coronaviruses But it exists.” Ahand in letter In the journal Nature Medicine last year, virologist Kristian Anderson and evolutionary biologist Andrew Rambaut argued that some genetic traits found in SARS-CoV-2 may be relatively rare in the genome. coronavirus But it can still be explained through natural mutations. or reunification
Contrary to right-wing disinformation some scientists ever do Take the possibility of laboratory leaks seriously from the very beginning of the epidemic. Unfortunately, the early debates Much of this wasted in dealing with unsupported assertions as to whether the virus is explicitly genetically engineered. deliberately let go It’s a biological weapon laced with HIV. Otherwise, it seems that only circumstantial evidence As for the possibility that laboratory accidents are bringing more viruses to the human population, for example, the Wuhan Institute of Virology works with coronavirus And some of the scientists working there seem to be sick too. flu-like disease Around the time of the first outbreak in November
That said, there is also circumstantial evidence for the theory of natural origin and many scientists per to be believed to have originated from animals to humans—This means that the virus that appears in animals then crosses over to humans. It is possible through an intermediate host. It’s still the most probable scenario. in fact this happen all time. Some have admonish that we will never know the truth Or it may take years to find natural reservoirs, if any.
no matter where the virus comes from The Chinese government continued to conceal information: during the first weeks and months of the outbreak. Government officials tried sensor Scientists, doctors and people that try to warn people about the dangers of new illnesses But China’s liability hardly helps the US. and other countries can be acquitted. failure When the virus arrives at your doorstep
