A team of scientists say it is “beyond reasonable doubt” the Covid pandemic started with infected animals sold at a market, rather than a laboratory leak.

They were analysing hundreds of samples collected from Wuhan, China, in January 2020.

The results identify a shortlist of animals – including racoon dogs, civets and bamboo rats – as potential sources of the pandemic.

Despite even highlighting one market stall as a hotspot of both animals and coronavirus, the study cannot provide definitive proof.

The samples were collected by Chinese officials in the early stages of Covid and are one of the most scientifically valuable sources of information on the origins of the pandemic.

Their analysis was published last year and the raw data made available to other scientists. Now a team in the US and France says they have performed even more advanced genetic analyses to peer deeper into Covid’s early days.

    There’s a bunch of indications / conspiracy theories that it might have been a lab leak. Basically there’s not really a way to know unless the Chinese government starts being more forthcoming with information.

    The main reason the conspiracy theory started is because the city where it started had a world renowned virus research facility in it.

    Of course, the reason the facility is there in the first place is because Wuhan province is a place where a lot of viruses originate naturally (in bat colonies), so it makes sense you research the viruses close to their natural reservoir.

      Wuhan province is a place where a lot of viruses originate naturally (in bat colonies)

      This is disingenuous. RaTG13 was sourced in Tongguan in Mojiang Hani Autonomous County 1800km from Wuhan.

      • I don’t have any information to add one way or the other, but it kinda sounds like you’re saying the fact that one bat-bourne illness was found elsewhere, it’s impossible that Wuhan has many or any such viruses too, which seems pretty fallacious.

          No. Its pretty fallacious to imply WIV was only looking at local bats.

          The wuhan area certainty has many viruses, but none were anywhere close to the sample found 1800 km away, which WIV certainty had a copy of because they sequenced it.

            I don’t think anyone said they were only looking at local viri. The original comment said (emphasis mine)

            Of course, the reason the facility is there in the first place is because Wuhan province is a place where a lot of viruses originate naturally (in bat colonies), so it makes sense you research the viruses close to their natural reservoir.

            So Wuhan was ideal because it’s where a lot of viri originate. That doesn’t imply they only looked at viri from nearby just that the location was chosen because there were so many nearby.

        … what? Bats are virus factories due to how their biology/immune system works. They opened a lab in Wuhan to study any novel viruses coming out of the local bat population. That’s what that person is referencing. Your counter is basically a non sequitar.

          coming out of the local bat population

          My point is that the word local is both incorrect and misleading. Bats from 1800km away are not local.
