NEW YORK: Covid-19 probably came to people through an animal, and likely started spreading no more than a month or two before it was noticed in December of 2019, a World Health Organization draft report finds.
The least likely source: a laboratory leak, the WHO’s joint international team concluded.
WHO is scheduled to release the final report on its investigation into the origins of coronavirus on Tuesday, but a draft version of the report obtained by CNN shows there’s still no smoking gun and no evidence suggesting the virus was spreading any earlier than the very end of 2019.
The report gives four possible sources for the virus and the most likely scenario is via an intermediate animal host, possibly a wild animal captured and then raised on a farm.
But the investigation has not found what other animal was infected by a bat — considered the most likely original source of the virus — and then may have transmitted it to a human. “The possible intermediate host of SARS-CoV-2 remains elusive,” it reads.
