French scientist finds previously undisclosed data from Chinese research team.
A scientific sleuth in France has identified previously undisclosed genetic data from a food market in Wuhan, China, that she and colleagues say support the theory that coronavirus-infected animals there triggered the COVID-19 pandemic. Several of the researchers presented their findings on Tuesday to the Scientific Advisory Group for the Origins of Novel Pathogens (SAGO), an expert group convened last year by the World Health Organization (WHO).
“The data does point even further to a market origin,” says Kristian Andersen, an evolutionary biologist at Scripps Research who attended the meeting and is one of the scientists analyzing the new data. If so, the findings weaken the view of a vocal minority that a virology lab in Wuhan was the likely origin of SARS-CoV-2, perhaps when the coronavirus infected a lab worker who spread it further.
