Newly-Published Evidence Undermines China Lab-Leak Theory (yahoo.com) 442

In 1999 Los Angeles Times reporter Michael Hiltzik won a Pulitzer Prize. Now a business columnist for the Times, he writes that "new evidence undermines the COVID lab-leak theory — but the press keeps pushing it." A paper posted online [in September] chiefly by researchers at France's Institut Pasteur and under consideration for publication in a Nature journal...reports that three viruses were found in bats living in caves in northern Laos with features very similar to SARS-CoV-2, the virus responsible for COVID-19. As Nature reported, those viruses are "more similar to SARS-CoV-2 than any known viruses."

Another paper, posted in late August by researchers from the Wuhan lab, reports on viruses found in rats also with features similar to those that make SARS-CoV-2 infectious in humans.

Two other papers published on the discussion forum virological.org present evidence that the virus jumped from animals to humans at more than one animal market in Wuhan, not just the Huanan seafood market. Given that these so-called wet markets have long been suspected as transmission points of viruses from animals to humans because they sell potentially infected animals, that makes the laboratory origin vastly less likely, according to a co-author of one of the papers. "That a laboratory leak would find its way to the very place where you would expect to find a zoonotic transmission is quite unlikely," Joel Wertheim, an associate professor at UC San Diego's medical school, told me. "To have it find its way to multiple markets, the exact place where you would expect to see the introduction, is unbelievably unlikely."

As virologist Robert F. Garry of Tulane, one of Wertheim's co-authors, told Nature, the finding is "a dagger into the heart" of the lab-leak hypothesis.

          It is interesting. The high mutation jump you list is one of the great paradoxes of evolution theory, that we rarely find intermediary stages of evolution in the wild.

          Here's two questions which should lead you to the correct conclusion:
          How many distinct variants of COVID are out there, vs how many are actually tracking through the population? If your answer is thousands, and tens respectively you may see where I'm going with this:
          Follow up question: have you sampled all the bats of China?

              That may be part of it, but basic statistics would suggest that's not the real reason.
              Even if your sample only retrieves 1% of all samples, as long as the distribution is random, it's representative.

      • Not saying it happened. Personally, I don't feel that Occam's razor is applicable here. Some of the earliest confirmed cases have no tie to the wet market (according to epidemiological report that came out very early on from China). So a non wet-market origin theory has to be entertained.

      What it doesn't prove is who/what inserted the dangerous bits at the furin cleavage site (that's also not present in any natural viruses the scientist community have studied so far).

      This says otherwise:

      Such a polybasic furin cleavage site is found in various proteins from many viruses, including Betacoronavirus Embecoviruses, and the Merbecovirus. However, within the betacoronaviruses of the sarbecovirus lineage B, this type of site is unique to SARS-CoV-2.

However what we KNOW is that the Chinese refused to provide the data that would have enabled the lab leak hypothesis to be established, and bullied the WHO into being dishonest about their investigation's report. This behaviour continues despite Western media overwhelming the attempts to cover up.

    The "lab leak hypothesis" covers many possible scenarios, some of them far-fetched, and some of them quite plausible, none of which I can see are actually ruled out by this.

    The most extreme lab leak scenarios are so unlikely that it would be hard to "disprove" them further, but their conspiracy-theory robustness means evidence will never change anyone's minds. You can't debunk a conspiracy theory, because they aren't powered by evidence; they exist to affirm somebody's world view. No matter what evidence you raise, the conspiracy theorist can trump it with a hypothetical, usually someone acting in an incredibly stupid way. Authoritarian regimes are the conspiracy theorist's best friend though: they actually *do* do stupid things to hide evidence, even when that evidence would have very little impact.

    The more likely lab leak scenarios involve accidents: samples that have not been characterized that are mishandled, infected animals coming in contact with unprotected lab workers, scientists in the field being infected and bringing that infection back. It's basically impossible to disprove these scenarios by any demonstration that the virus is somehow *natural*.

    Evidence that the virus emerged from multiple wet markets in Wuhan, if it stands up to scrutiny, *does* tend to lend credence to an animal trade connection, but that doesn't actually disprove anything else.

    Along with Times staff writer Chuck Philips, Hiltzik won the 1999 Pulitzer Prize for their series on corruption and bribes in the music industry.

    So that makes him an expert on virology? Interesting.

    The "smoking gun" in the study discussed in this article [virological.org] deal with the Lineage A and Lineage B strains of the virus, which were both sampled from people and animals in the marketplace at the same time on December 30, 2019. The fact that two different lineages were found both in people and in animals at that time is their evidence that both must have been circulating in animals, and thus both jumped to humans from those animals.
    There are numerous problems and counter-evidence that this does not discount the lab-leak (or single-source) scenario.

    1) Studies and evidence show that COVID originated in China in mid-November [sciencedaily.com], 2019. Additionally the NIH found evidence [washingtonpost.com] of cases in the USA in December, 2019 "A 2020 study in blood donation specimens collected among residents of 9 states between 13 December and 17 January found antibodies to SARS-CoV-2 in the United States as early as mid-December 2019". This means that COVID had been spreading amongst humans for around 45 days before the samples were collected that these studies are based on.
    2) Humans easily transmit COVID to animals. In fact, due to our size, how much we tend to cough and sneeze when sick, and how high our heads are above the ground, humans are vastly better virus-spreaders than the animals in those wet markets. Pet dogs and cats, and even wild animals in zoos, have all been infected with COVID from people. Not only is it realistic, but it is totally expected, that live animals stuck in cages in wet markets would be infected with COVID from the thousands of people walking by and looking at them from above.
    3) The timing of two strains jumping from animals to people at the same time is suspect. Basically this study says that there are two lineages in December 30, 2019, and thus both those lineages must have jumped at the same time to people from different animals in different markets. This is extremely unlikely timing.

    The study and article totally ignore the following:
    1) One or both lineages could have been isolated in the Wuhan laboratory and one or both strains could have leaked from that laboratory.
    2) Since humans had been infected for over a month and a half before the samples were collected, humans could have infected animals in markets with one or both lineages. It is to be expected that animals susceptible to COVID kept in the market-place environment would be infected with it by humans.
    3) The jump from animal reservoirs to humans is a likely point in which a virus would mutate, due to the virus replicating in a very different host. It is possible one of the two lineages was an early human mutation that was spread back to animals in the market by humans.

    The main issue is that none of this precludes or even reduces the possibility that someone in the Wuhan laboratory was accidentally infected with COVID. Due to the extremely unlikely timing in the study claiming that two people were infected by two different lineages of COVID at the same time in two different places, it is no more unlikely that the source of one of the strains was a laboratory leak and the source of the other strain was from animal infection.

    The fact (which isn't a fact as it wasn't proven either) that one source of animal to human infection occurred does not mean that ALL

    I don't think we'll ever know, definitely, anything, other than Wuhan is where it started.

    The scary part is the discussion as to whether or not it was created in a lab. I never read or saw in any live discussion that it was impossible to create - just that it was likely to be of natural origin. It would be prudent to assume then, that a deadly virus could be built entirely in a lab environment.

    I accept that Covid-19 is almost certainly an animal-to-human transfer. The next pandemic is likely to start the same way. But given CRISPR-Cas9 and other advances in genomics, and looking forward fifty years, someone, somewhere, will build something viral and very deadly. Because Humans.

Adding features does not necessarily increase functionality -- it just makes the manuals thicker.
