The report, published Thursday in the prestigious journal Science, revives the debate as to whether the pandemic was triggered by an outbreak from wildlife sold in the market, a leak from the Wuhan Virology Lab or some other way.
This year a joint study by China and the World Health Organization (WHO) debunked the theory that Covid-19 originated in a laboratory, saying it was most likely transmitted naturally to humans. , possibly through the wildlife trade. News agency Reuters,
A team of WHO-led experts had spent nearly four weeks in and around the central city of Wuhan with Chinese scientists and concluded their joint report in March that the SARS-CoV-2 virus was transmitted from bats to humans in other animals. Most likely to have been transmitted through the medium, but noted that further research was needed.
Michael Vorobey, chief of ecology and evolutionary biology at the University of Arizona, said the accountant, who is believed to be the first case, reported that its first symptoms appeared on December 16, several days after they were initially known. Journal Science on Thursday.
Several experts, including one of the WHO-selected pandemic investigators, said Vorobey’s research was accurate and that the first known case of Covid was most likely a seafood vendor.
On 8 December, he had a contusion due to a dental problem. “Their symptom onset followed several cases among workers at Huanan Market, with the earliest known case being a female seafood vendor, the onset of illness on December 11,” the study said. According to the agency.
The report noted that most of the initial symptomatic cases were linked to the market, particularly from the western segment where raccoon dogs were caged, and provided strong evidence of the epidemic’s live-animal market origins.
In October, the WHO proposed a new expert panel here to investigate the source of the coronavirus.
