The virus started the 2019–20 coronavirus outbreak.[5][6][7] The first suspected cases were reported to the WHO on December 31, 2019.[8][9] Many early cases of this new coronavirus were linked to Huanan Seafood Wholesale Market, a large seafood and animal market in Wuhan, China. The virus may have come from infected animals. It is not certain that this place was the source of the pandemic.[10]
