“When you look at all of the evidence together, it’s an extraordinarily clear picture that the pandemic started at the Huanan market,” said Michael Worobey, an evolutionary biologist at the University of Arizona and a co-author of both new studies. “I think what they’re arguing could be true,” said Jesse Bloom, a virus expert at the Fred Hutchinson Cancer Research Center. “But I don’t think the quality of the data is sufficient to say that any of these scenarios are true with confidence.”In a separate study published online Friday, scientists at the Chinese Center for Disease Control and Prevention analyzed genetic traces of the earliest environmental samples collected at the market, in January 2020.
These findings came as a surprise. In the early days of the pandemic in China, the only COVID cases linked to the market appeared to be Lineage B. And because Lineage B seemed to have evolved after Lineage A, some researchers suggested that the virus arrived at the market only after spreading around Wuhan.
But the Chinese government has come under fire for not being forthcoming about the early days of the pandemic. Still, the WHO left many researchers dissatisfied. Worobey and Bloom signed a letter, along with 16 other scientists in May 2021, calling for more investigation into the origins of COVID — including the possibility that SARS-CoV-2 had escaped from a lab.
These patterns pointed to the market as the origin of the outbreak, Worobey and his colleagues concluded. The researchers ran tests that showed it was extremely unlikely that such a pattern could be produced merely by chance.But David Relman, a microbiologist at Stanford University, raised the possibility that these patterns might be just evidence that the market boosted the epidemic after the virus started spreading in humans somewhere else.
Another co-author, Chris Newman, a wildlife biologist at the University of Oxford, was part of a research team that documented a number of live, wild mammals for sale at the Huanan market in November and December of 2019, including raccoon dogs. The Chinese CDC study published Friday revealed a Lineage A coronavirus on a glove collected when the market shut down.
uhuh
Bogus propaganda It came from a communist Chinese lab
There are strong evidences that the first coronavirus was found near the rivers of michigan....
