International experts investigating the origins of Covid-19 have all but dismissed a theory that the virus came from a laboratory in China.
Peter Ben Emba-rek, the head of the World Health Organization WHO mission, said it was “extremely unlikely” that the virus leaked from a lab in the city of Wuhan.
He said more work was needed to identify the source of the virus.
The comments came at the conclusion of a joint WHO-China mission.
