Scientists Again Link Covid Pandemic Origin to Wuhan Market Animals (msn.com) 131

The Washington Post reports: An international team of scientists published a peer-reviewed paper Thursday saying genetic evidence indicates the coronavirus pandemic most likely originated with a natural spillover from an animal or animals sold in a market in Wuhan, China, where many of the first human cases of covid-19 were identified. The paper, which appears in the journal Cell, does not claim to prove conclusively that the pandemic began in the Huanan Seafood Wholesale Market, and it is unlikely to end the acrimonious and politicized debate over the coronavirus's origin... "The results we see are consistent with infected animals, but we cannot prove that they were," said Florence Débarre, an evolutionary biologist at the French National Center for Scientific Research and a co-author of the new paper...

Many of the 23 authors of the paper are known to have long supported a market origin for the virus. In an informal report in March 2023, they presented a central feature of the genetic data — the confirmation that animals potentially capable of triggering a pandemic were in the market... The new paper in Cell is longer, more comprehensive, probes a broader range of questions, and includes more data from the market and early-patient cases than the international team's informal 2023 report, Débarre said. Both the earlier and the new reports document that traces of the virus were found clustered in a section of the Huanan Seafood Wholesale Market where genetic traces of animals were also found. Several of those species — raccoon dogs, rabbits and dogs — are known to be susceptible to infection with SARS-CoV-2, the virus that causes covid. Raccoon dogs have also been shown experimentally to be capable of transmitting the virus. A significant element of the new paper is an analysis of when the pandemic began. Scientists can study mutations of the coronavirus, which evolves at a relatively steady rate, to estimate when the millions of genomes deposited in databases had the most recent common ancestor. That genetic evidence points to mid-November 2019 as the most likely time the virus spilled into humans and began spreading, and there could have been two or more spillover events, the researchers said.

"The timing of the origin of the market outbreak is genetically indistinguishable from the timing of the origin of the pandemic as a whole," the report states. There are many independent lines of evidence pointing to the market as the epicenter of the pandemic, said Kristian Andersen, an infectious-disease researcher at Scripps Research in La Jolla, Calif., and a co-author of the report in Cell. No previous virus spillover has been so well-documented, he said. "Of any previous outbreak, pandemic, you name it, we don't have this level of granularity," he said. "We can narrow it down to a single market, and narrow it down to a section in that market, and maybe even narrow it down to a single stall in that market. That is mind-boggling...." The genetic evidence, the new report contends, supports the hypothesis that SARS-CoV-2 emerged in the same way that SARS-CoV-1 — which sickened people in 2002-2003 but was extinguished before it could cause a full-blown pandemic — is widely believed to have started, from animals sold in a market.

The authors contend the world needs to take more aggressive action to shut down the illegal trade in wildlife to lower the risk of another catastrophic pandemic... There is no evidence that the virus, or its progenitor, was inside a laboratory before the outbreak.... "To the question — Did it come from a lab or come from a market? — I think we already knew the answer to that," Andersen said. "Yep, it's the market. It's natural, as we've previously seen happen."

One co-author posted a summary on X.com "If you don't want to read the papers."
  • "Early cases centered around the market (not a lab)"
  • "Environmental swabs that tested positive for SARS-CoV-2 clustered in the corner of the market where animals were sold."
  • "There were 2 lineages of SARS2 that spilled over separately at Huanan."

        That's an unfair criticism. He's using "MumbleGrumble" as a type specifier, not as an instance. And in the model he's presenting, the "MumbleGrumble" could be responding to, e.g. either magnetic fields or vibration. Say that it was supposed to detect magnetic fields, but could also respond to vibration and you have a reasonable objection.
        I don't believe the objection is valid, as I think the model is a poor analogy, but if you accept the model then his objection is valid.

      There is no such thing as falsifiability with history, there is no way to prove scientifically that Jesus was born, and therein lies the problem. Even if we take as granted that the covid pandemic was tied to Wuhan market, it is fundamentally impossible to prove how the animals in the market got sick, they could have acquired the virus from one of the lab workers at the Wuhan Institute of Virology, even if we accept everything that the authors say is true.

      I would also like to mention, that every major world power has a bioweapons program, including the United States. Chinese generals have also purportedly wanted to develop ethnic bioweapons, and the Covid hysteria by Government Officials was an attempt to not look weak, i.e. to portray that we are not vulnerable to a bioweapons attack.

        Indeed, from what we've seen and the way the lab was working, there are two possibilities which would implicate both the lab and the market.

        1. The virus appeared in the market and the lab was working furiously to try to understand what was happening. In their haste, they released the virus further.

        2. The virus leaked from the lab. In order to cover it up, the virus was introduced into the market.

        I guess there's a third possibility of two simultaneous leaks as well although that seems to be a bit far-fetched.

      • Or they could have been infected by the CIA in an effort to start a pandemic in China as an act of biological warfare. You can choose any cause that appeals to you and make the case for it to the satisfaction of people who share your beliefs. If you are Chinese its those venal Americans. If you are American its those venal Chinese. And god forbid you suggest there is any moral equivalency that would make both equally unlikely.

      That depends on whether you are trying to calculate "most probable", or looking for certainty. You sure won't find certainty, and estimating probabilities is quite difficult. (And I favor a theory different from either of the two dominant theories.)

      But you can always estimate probabilities. The problem is calculating your error bars (degrees of certainty).

    If they think it was spread from Nov 2019 in Wuhan, they should probably have checked the flights from SFO to Seattle in October when I first got it. I can still remember not being able to stop coughing unless I had a cough drop in my mouth and I was burning up on that flight. I know it was the same covid-19 because I have gotten that same virus and it temporarily damages my kidneys each time. I get magnesium and calcium reabsorption issues each time that drop my energy levels significantly, call it long haul covid or the reason why so many people died one or two months after recovery from hospitalizations, I know I beat it because I was lucky enough to learn how to counter some early low magnesium symptoms. So, yeah, no Wuhan believer here. My dad even had the same symptoms that same month and went on get kidney stage for 4 disease after it took out his kidneys, again this was October 2019 before any Wuhan outbreak occurred.

    I don't understand the false binary here.

    The VERY FIRST story I heard about the origin from a friend from southern China was that it was probably a lab tech or maintenance person, tasked with "disposing" of a batch of lab animals.
    Seeing a side-opportunity to make some $, he sells them to a friend that works the wet market. They may have even all been rated as healthy failed test animals or something so it wasn't even deliberate or (in his view) dangerous.

    I have to say, it still rings credible to me. I *don't* believe any Chinese researcher would have released it deliberately. I *do* believe that Chinese society works on an astonishing level of corruption as 'accepted practice'.

    But to this point: it illustrates that "it came from the lab" and "it came from the market" are NOT EXCLUSIVE, and the...constant effort to insist that "it must be our definition because the other one is ONLY this extreme alternative" frankly smells more of desperate attempt to cover something up by strawmanning alternatives to absurdity.
