Genetic material collected at a Chinese market near where the first human cases of COVID-19 were identified show raccoon dog DNA comingled with the virus, international experts say.
The Huanan Seafood Wholesale Market, sits closed in Wuhan in central China's Hubei province on Jan. 21, 2020. International scientists have examined previously unavailable genetic data from samples collected at a market in China close to where the first human cases of COVID-19 were detected and said they have found suggestions the pandemic originated from animals, not a lab.
He criticized China for not sharing the genetic information earlier, telling a press briefing that “this data could have and should have been shared three years ago.” “There’s a good chance that the animals that deposited that DNA also deposited the virus,” said Stephen Goldstein, a virologist at the University of Utah who was involved in analyzing the data. “If you were to go and do environmental sampling in the aftermath of a zoonotic spillover event … this is basically exactly what you would expect to find.”
“What this does provide is clues to help us understand what may have happened,” she said. The international group also told WHO they found DNA from other animals as well as raccoon dogs in the samples from the seafood market, she added. Goldstein and his colleagues say their analysis is the first solid indication that there may have been wildlife infected with the coronavirus at the market. But it is also possible that humans brought the virus to the market and infected the raccoon dogs, or that infected humans simply happened to leave traces of the virus near the animals.
