He has spent his career tracking down the origins of pandemics, including the origin of HIV and the 1918 flu.īack in May 2021, Worobey signed a letter calling for an investigation into the lab-leak theory. Worobey is a research professor in the Department of Ecology and Evolutionary Biology at the University of Arizona.Įvolutionary biologist Michael Worobey helped lead two of the studies and has been at the forefront of the search for the origins of the pandemic. He has tracked the origins of the 1918 flu, HIV and now SARS-CoV-2. That outbreak also spilled over into the surrounding community, as one of the new studies shows. So now, for the first time, the timing of the earliest known coronavirus infections coincides almost exactly with the timing of the outbreak at the seafood market, which began in early December and likely involved hundreds of people working or shopping at the market. It predicts the coronavirus jumped into people once in late November or early December and then again few weeks later. And a new genetic analysis estimates the time, within weeks, when not just one but two spillovers occurred. Photographic and genetic data pinpoint a specific stall at the market where the coronavirus likely was transmitted from an animal into people. The new data paints an incredibly detailed picture of the early days of the pandemic. What's more, the caged animals are shown in or near a stall where scientists found SARS-CoV-2 virus on a number of surfaces, including on cages, carts and machines that process animals after they are slaughtered at the market. They provide photographic evidence of wild animals, which can be infected with and shed SARS-CoV-2, sitting in the market in late 2019 - such as raccoon dogs and a red fox. Neither of the papers provides the smoking gun - that is, an animal infected with the SARS-CoV-2 coronavirus at a market.īut they come close. "But they absolutely are pushing it toward an animal origin." "The studies don't exclude other hypotheses entirely," says virologist Jeremy Kamil, who's at Louisiana State University Health Shreveport and was not involved in this research. In reaction to the papers, they say the data tips the scales toward wildlife sold at the market. Scientists who weren't involved in the research papers have called the new data " very convincing" and a " blow" to the lab-leak theory - that the virus somehow escaped from the Wuhan Institute of Virology, which does research on coronaviruses. Specifically, they conclude that the coronavirus most likely jumped from a caged wild animal into people at the Huanan Seafood Wholesale Market, where a huge COVID-19 outbreak began in December 2019. This week, an international team of scientists published two extensive, peer-reviewed papers in Science, offering the strongest evidence to date that the COVID-19 pandemic originated in animals at a market in Wuhan, China. Could one of these wild animals have triggered the entire COVID-19 pandemic late in 2019? Was it a few raccoon dogs, inside a metal cage and stacked on top of a chicken coop? Or perhaps a lone red fox, curled up in the corner of its cage. Two new studies document samples of SARS-CoV-2 from stalls where live animals were sold. 11, 2020, after the market had been closed following an outbreak of COVID-19 there. ![]() Security guards stand in front of the Huanan Seafood Wholesale Market in Wuhan, China, on Jan.
