Four of the eight intelligence agencies lean toward a natural origin for the virus, with "low confidence," while two of them – the DOE and the Federal Bureau of Investigation – support a lab origin
But at the end of the day, the origin of the pandemic is also a scientific question. Virologists, who study pandemic origins, are much less divided than the U.S. intelligence community. They say there is "very convincing" data and "overwhelming evidence" pointing to an animal origin.
In particular, scientists published two extensive, peer-reviewed papers in Science in July 2022, offering the strongest evidence to date that the COVID-19 pandemic originated in animals at a market in Wuhan, China. 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.
They provide photographic evidence of wild animals such as raccoon dogs and a red fox, which can be infected with and shed SARS-CoV-2, sitting in cages in the market in late 2019. 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.
NPR: So what is the likelihood of that coincidence happening — that the first cluster of cases occurs at a market that sells animals known to be susceptible to SARS-CoV-2, but the virus didn't actually come from the market?
I would put the odds at 1 in 10,000. But it's interesting. We do have one analysis where we show essentially that the chance of having this pattern of cases [clustered around the market] is 1 in 10 million [if the market isn't a source of the virus]. We consider that strong evidence in science.
The analyses that we've done are telling a very strong story.
The evidence is amongst the best we have for any emerging virus.
