More Evidence Covid-19 Originated at Wuhan Market in Two New Studies (cnn.com) 394

"Two new studies provide more evidence that the coronavirus pandemic originated in a Wuhan, China market where live animals were sold," reports the Associated Press, "further bolstering the theory that the virus emerged in the wild rather than escaping from a Chinese lab."

CNN reports: "All eight COVID-19 cases detected prior to 20 December were from the western side of the market, where mammal species were also sold," the [first] study says. The proximity to five stalls that sold live or recently butchered animals was predictive of human cases... The "extraordinary" pattern that emerged from mapping these cases was very clear, said another co-author, Michael Worobey, department head of Ecology and Evolutionary Biology at the University of Arizona.

The researchers mapped the earliest cases that had no connection to the market, Worobey noted, and those people lived or worked in close proximity to the market. "This is an indication that the virus started spreading in people who worked at the market but then started that spread ... into the surrounding local community as vendors went into local shops, infected people who worked in those shops," Worobey said.

The other study takes a molecular approach and seems to determine when the first coronavirus infections crossed from animals to humans.... The researchers suggest that the first animal-to-human transmission probably happened around November 18, 2019, and it came from lineage B. They found the lineage B type only in people who had a direct connection to the Huanan market.

"All this evidence tells us the same thing: It points right to this particular market in the middle of Wuhan," said Kristian Andersen a professor in the Department of Immunology and Microbiology at Scripps Research and coauthor of one of the studies. The AP quotes Andersen as saying "I was quite convinced of the lab leak myself until we dove into this very carefully and looked at it much closer." Andersen said they found case clusters inside the market, too, "and that clustering is very, very specifically in the parts of the market" where they now know people were selling wildlife, such as raccoon dogs, that are susceptible to infection with the coronavirus.... Matthew Aliota, a researcher in the college of veterinary medicine at the University of Minnesota, said in his mind the pair of studies "kind of puts to rest, hopefully, the lab leak hypothesis."

"Both of these two studies really provide compelling evidence for the natural origin hypothesis," said Aliota, who wasn't involved in either study. Since sampling an animal that was at the market is impossible, "this is maybe as close to a smoking gun as you could get."

CNN notes that Worobey also had initially thought the lab leak had been a possibility, but now says the epidemiological preponderance of cases linked to the market is "not a mirage. It's a real thing.

"It's just not plausible that this virus was introduced any other way than through the wildlife trade." To reduce the chances of future pandemics, the researchers hope they can determine exactly what animal may have first become infected and how.

"The raw ingredients for a zoonotic virus with pandemic potential are still lurking in the wild," said Joel Wertheim, an associate adjunct professor of medicine at the University of California, San Diego. He believes the world needs to do a much better job doing surveillance and monitoring animals and other potential threats to human health.

    It's as if the most likely explanation is the correct one!

    A constant stream of wild animals being transported to and sold in the Wuhan market would eventually transmit a form of the disease which easily infect from human to human - who would have thought!

    Buyers and sellers working in close proximity to the known animal reservoir of a fast evolving virus, day in, day out, for years and years - it's as if that is much more likely to cause a pandemic - than some researcher manage to hit the exact kinds of mutations needed, or find the exact virus, and then for one single unlikely event to spread it and outcompete all the coronavirus variants in the bats in the market.

      Yes, it's just totally bat crazy (badum ching!) to think that a lab a stone's throw away that just happened to be studying coronaviruses (and adding to their functionality!) might deserve a look here as well.

      Yes but when have conspiracy nuts ever chosen the simplest, most likely explanation? Studies suggesting the mundane reasons are simply more evidence that Bill Gates and Antony Fauci colluding with the Chinese government released a weaponised virus via 5G masts so they could profit from mind control injections.

      Yes, I agree that CERN probably gated it in from Hell.

      And since it's hell-spawn, that explains why it doesn't respond to good patriotic treatments like Ivermectin and gargling Chlorox.

    Hint: it's quicker to assume politicians from all countries are lying, but this is especially true of China's.

    Oh dear. It seems my esteemed colleague scientists have forgotten that correlation is not causation. These finding are not smoking guns, but evidence of action by Patient Zero. There is no evidence that the crossover happened at the market, only that the spread was rooted there.

    It's just as plausible that someone from the lab became infected in an unrealized exposure, thought they had a cold, went later to shop at the market and had a good sneeze, infecting a handful of people. The lab rat then went hom

    It's amazing -- and incredibly disappointing -- how hard the scientific community has tried to prove that the virus didn't come from the lab. Is there a single paper that suggests it came from the lab? Anyone interested in researching that direction knows it would be processional suicide. Just look at the treatment Alina China got when she wrote Viral -- death threats, professionally ostracized, accusations of being a "race traitor." It's a fantastic book which lays out in meticulously researched detail the overwhelming range of evidnece pointing at the lab.

    All we have now is papers that look at the data the Chinese authorities have not destroyed, altered or redacted. Surprise, surprise, none of it points to the lab. I've never been so disappointed in the scientific community's willingness to engage in coordinated ass-covering because it's quite a bit of professional egg on your face to kill 6 million people.

    In March 2020, a directive from the Chinese government — highlighted by the Associated Press — instructed researchers at universities, companies and medical institutions to have all studies on COVID-19 vetted by government research units and then published under the direction of public opinion teams. Those who don’t follow procedures, the document warned, “shall be held accountable”.

    That's from Nature [nature.com]. And take a quick minute to look at which does point a giant finger at the lab. [originofcovid.org]

      Maybe the reason why no reputable publications have published papers claiming it is from a lab is because there is no reputable science to suggest that it was.

      The whole conspiracy theory doesn't hold up anyway, because the claimed lie that it originated in a web market that the Chinese government had been repeatedly warned was going to produce something like this, is hardly covering them in glory. Especially after SARS and swine flu, everyone knew this was how these things happen and that wet markets needed

        Again, the Chinese authorities have done their utmost to prohibit and inhibit investigation into the WIV. As clearly demonstrated in the Nature article I linked.

        The whole conspiracy theory

        Ah, you show your colors. It's a "conspiracy theory." You clearly didn't read the other link I provided. I double dare you to get a copy of Viral, read it, and think for yourself.

        Especially after SARS

        Indeed, SARS-COV, the virus for which they found an intermediary host and which was not very transmissible between humans during the 2003 outbreak. Then there's SARS-COV-2 which appeared on the scene right next to a viral research facility that was doing gain-of-function research on bat coronaviruses. The same low-security facility which had a history of safety issues (per state department memos). Despite lots of hunting, no intermediary host has been found for SARS-COV-2. We're supposed to believe that a bat virus in a wet market (where no bats were being sold) was riding along in another animal and then hopped over to humans and was immediately and amazingly well-tuned for human to human transmission.

        But yes, dear, it's all a conspiracy theory.

          "Buy and read this book" isn't the killer argument you think it is.

          It is a conspiracy theory when there aren't any papers published in peer reviewed, reputable (or even disreputable) journals. As you say, the Chinese have not been forthcoming with access, so it's at best speculation.

          Note also that the absence of bats at the market is not the trump card you think it is. The research presented here suggests that the market was the original spreader event, not necessarily the point at which it jumped to humans. So whoever got it first might simply have visited the market and given it to others, having encountered bats elsewhere.

          Which is the same as the lab hypothesis. What these papers are saying is that the genetic lineage of the virus does not suggest lab growth, it appears to have gone from bats to pangolins to bats again and then to humans. Intermediaries have been found. Some people claim not enough intermediaries, which is an argument borrowed from those claiming that humans are not descended from apes. There's always one more intermediate stage you can shave it down to.

  • Started in the "wet market" AFTER it was released by the Wuhan lab, thanks to funding by Fauci's team who were told it was "too dangerous" to research gain of function, so they gave it to the Chinese Wuhan lab which is in the same "neighborhood" as the wet market.
  • Now do the lab leak and compare apples-to-apples.

    Until you do, stfu about how one is more or less likely than the other and about how clearly you can see under your favorite streetlight.

  • I'm sorry, but this is not convincing at all. Where the cases were discovered is not necessarily where the virus was contracted. Also, it's not as if we can expect any honesty, about anything, from the CCP. If you remember, the CCP also tried to claim the virus came from Europe.

    There is very substantial evidence that the virus was man-made. The location of the Wuhan lab is not the only evidence of the virus being created in a lab. Although the nearby Wuhan lab exists specifically to create such viruses.

    The WHO visited the Wuhan Institute of Virology, one year after the original infections, took no samples, spent four hours at the lab examining Chinese provided documents and then went home.

    FACT: The lab performed Gain of Function experiments on bat coronavirus' to become potentially more infectious to humans. These GoF experments were part funded by the NIH. This funding was provided to a private company with financial links to Fauci.
