Scientists recently released studies that point to a large food and live animal market in Wuhan, China, as the origin of the coronavirus pandemic.

Analyzing a wide range of data, including virus genes, maps of market stalls and the social media activity of early Covid-19 patients across Wuhan, the scientists concluded that the coronavirus was very likely present in live mammals sold at the Huanan Seafood Wholesale Market in late 2019 and suggested that the virus spilled over into people working or shopping there on two separate occasions.

In a separate study published online on Friday February 25th, 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.
