A new report suggesting that the coronavirus may have originated in raccoon dogs has energized scientists who have long argued that the pandemic began at a wildlife market in Wuhan, where the pathogen jumped from animals to humans.
But to the smaller faction of researchers who maintain that the coronavirus was the result of a laboratory accident, the raccoon dog findings —— failed to produce convincing evidence of a natural origin that rules out human involvement.
“I'm optimistic that more evidence will be made public,” Chan said, “and proponents of either hypothesis can reevaluate their confidence at that time.” Daszak has backed the zoonotic hypothesis from the start of the pandemic. “To me,” Daszak said in a telephone interview, “it’s another piece of evidence that the market was where it began, not the lab.”
Andersen, Worobey and Holmes have not made their work available to the public. None of them responded to Yahoo News requests for comment. Raccoon dogs were already known to be susceptible to coronavirus. The far more difficult question is whether raccoon dogs could have served as the inadvertent vehicle for an entirely new pathogen. For that to be true, there would presumably exist an earlier version of the coronavirus, specifically adapted to raccoon dogs — but not yet adapted to humans.
The data uploaded to GISAID “doesn't distinguish whether the virus in the wildlife stall was brought there by a raccoon dog or by a person infected due to the superspreading in the market,” Chan said. “It doesn't even tell us if the raccoon dog was infected or if a surface contaminated by a sick person and the raccoon dog had been swabbed.”
