Their findings, which were published in Science, confirm that the first cases appeared in late November, or early December 2019. They believe that live animals infected with the virus were then sold and caused the spread of covid to vendors, customers and then the wider public.
This information is not completely new, given that many pointed to Wuhan as the eye of the storm early on in the pandemic - but it does confirm what was long expected.

"From the clinical observations in Wuhan, around half of the earliest known Covid cases were people directly linked to the seafood market," evolutionary biologist Michael Worobey told NPR. "And the other cases, which aren't linked through epidemiological data, have an even closer geographical association to the market."
He added: "That's what we show in our paper. It's absurd how strong the geographical association is."
While confirming the likelihood of a major outbreak at the market without a source of the virus was very slim, Worobey also said that the odds of the virus not having an origin in the market are about "1 in 10,000."
