The team of experts sent by the World Health Organization (WHO) to investigate the origins of the COVID-19 pandemic in Wuhan, China, say they found no evidence of an outbreak related to the virus in the city prior to 2019.
Giving an update on their findings the day before they depart China, Peter Ben Embarek from the WHO delegation said the picture they had of the situation before their investigation had not changed dramatically.
Speaking alongside a Chinese scientific delegation, Embarek said the team embarked on a search for cases earlier on in 2019, concluding that they “did not find evidence of large outbreaks that could be related to cases of COVID-19 prior to December 19 in Wuhan or elsewhere.”
“We can also agree we have found evidence of a wider circulation of the virus in December. It was not just a cluster outbreak in Wuhan markets but it was also circulated outside of the markets.”
More than a year after the start of the coronavirus crisis that has engulfed the planet, the investigators spoke alongside officials in Wuhan, where the first cases of the virus were discovered in December 2019.
Liang Wannian, the head of the Chinese scientific delegation, said that transmission from an animal is likely but the animal “has not yet been identified”.
The WHO mission had a shaky start, with China seemingly reluctant to allow the experts to conduct their work, failing to provide clearances to some of the team.
The experts arrived in China in January and visited key places linked to the initial outbreak, including meat and fish markets where early cases were found.
They also visited the virology institute in Wuhan, which the US has claimed as being the source of the virus’s escape.
The WHO has already warned that patience will be needed before finding a possible answer, a message reiterated by a member of the team, Dr Hung Nguyen-Viet, in an interview with AFP.
“We are in a process and we need time and effort to understand” what happened, explained the specialist, co-director of the human and animal health programme at the International Livestock Research Institute in Nairobi.
