An international team of scientists has determined that the earliest cases ofin humans arose at a wholesale fish market in Wuhan China in December 2019. They linked these cases to bats, foxes, and other live mammals infected with the virus sold in the market either for consumption as meat or for their fur. The team of 18 researchers included a scientist at the University of Utah Health.
Neighborhoods within a half-mile of the market were the only areas where the virus was spreading in December 2019. Some researchers had previously suggested that the virus was brought into the market from elsewhere in the city and spread among its patrons. Instead, the new findings strongly suggest that the virus originated in the market via live animal sales, and slowly spread from there into nearby neighborhoods and then the city at large.
