Researchers Pinpointed Covid-19's Origin to Within a Few Metres

Australia's public broadcaster interviewed a virologist who "played a key role in mapping the evolution of COVID-19" (and was also "the first person to release the sequence of SARS-CoV-2 to the world.") But interestingly, this Australian virologist also visited the Wuhan market in 2014, "and recognised the risk of virus transmission between animals and humans and suggested taking some samples." "While I was there, I noticed there were these live wildlife for sale, particularly raccoon dogs and ... muskrats" he said. "I took the photographs because I thought to myself: 'God, that's, that's not quite right'." Raccoon dogs had been associated with the emergence of a different coronavirus outbreak, SARS-CoV-1, in 2002-04, which became known worldwide as the SARS virus. Even in 2014, Professor Holmes believed the market could become a site of virus transmission between animals and humans. The monitoring that Professor Holmes suggested never took place but, in the early days of COVID-19, he was still convinced that a market like the one in Wuhan was the logical origin of the virus. "They are the kind of engine room of [this sort] of disease emergence ... because what you're doing is you're putting humans and wildlife in close proximity to each other," he said. The professor also describes the theory that the virus some how leaked from a Chinese lab as "horrendous, blame-game finger-pointing," noting that the nearest lab is miles away. And he cites other reasons the market is where the virus originated: Aside from the geographic clustering, he also points to the fact that two different strands emerged almost simultaneously in humans, something that is much more likely if the virus had already been mutating in animals. "They're sufficiently far apart that they were probably independent jumps. "It means there was a pool of infected animals in the market and it's mutated amongst them before it jumped to humans." All of this has led Professor Holmes to conclude that the question of how COVID-19 emerged is settled. "I'm extremely confident that the virus is not from a laboratory. I think that's just a nonsensical theory," he said. Detailed mapping of where samples were detected inside the Huanan seafood wholesale market allowed Professor Holmes and his colleagues to even pinpoint to a few square metres where COVID-19 was likely to have jumped between humans and animals. "It's extraordinary," he said. "And I took a photo in 2014 of one of the stalls that was the most positively tested in the whole market."
