No indication of Covid-19 virus in Wuhan before December 2019: WHO mission

There is insufficient evidence to determine that Covid-19 was being spread in China's central Wuhan before December 2019, a joint WHO and Chinese expert mission into the origins of the pandemic in Wuhan said Tuesday.

"There is no indication of the transmission of the Sars-Cov-2 in the population of the period before Dec 2019," said Liang Wannian, head of the China team, at a press conference, adding that there was "not enough evidence" to determine if the virus had spread in the city prior to that.
