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 Embarek, 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 investigation could now focus on South East Asia, one expert said.

The WHO team are currently at the end of their investigation mission.

Wuhan, in China’s central Hubei province, is the first place in the world that the virus was detected in 2019. Since then, more than 106 million cases and 2.3 million deaths have been reported worldwide.
