WHO report COVID likely first jumped into humans from animals

almost 3 years in Jamaica Observer

GENEVA (AP) - A joint World Health Organization-China study on the origins of COVID-19 says that transmission of the virus from bats to humans through another animal is the most likely scenario and that a lab leak is "extremely unlikely", according to a draft copy obtained by The Associated Press.
The findings offer little new insight into how the virus first emerged and leave many questions unanswered, but the report does provide more detail on the reasoning behind the researchers' conclusions.
The team proposed further research in every area except the lab leak hypothesis - a speculative theory that was promoted by former US President Donald Trump among others. It also said the role played by a seafood market where human cases were first identified was uncertain.
Dr Anthony Fauci, the top US infectious diseases expert, said he would like to see the report's raw information first before deciding about its credibility.
"I'd also would like to inquire as to the extent in which the people who were on that group had access directly to the data that they would need to make a determination," he said. "I want to read the report first and then get a feel for what they really had access to - or did not have access to."
The report, which is expected to be made public today, is being closely watched since discovering the origins of the virus could help scientists prevent future pandemics - but it's also extremely sensitive since China bristles at any suggestion that it is to blame for the current one.
Matthew Kavanagh of Georgetown University said the report deepened the understanding of the virus' origins, but that more information was needed.
"It is clear that that the Chinese Government has not provided all the data needed and until they do, firmer conclusions will be difficult," he said in a statement.
Last year an AP investigation found the Chinese Government was strictly controlling all research into its origins. And repeated delays in the report's release have raised questions about whether the Chinese side was trying to skew its conclusions.
"We've got real concerns about the methodology and the process that went into that report, including the fact that the Government in Beijing apparently helped to write it," US Secretary of State Antony Blinken said in a recent CNN interview.
China rejected that criticism yesterday.
"The US has been speaking out on the report. By doing this, isn't the US trying to exert political pressure on the members of the WHO expert group?" asked Foreign Ministry spokesperson Zhao Lijian.
Still, suspicion of China has helped fuel the theory that the virus escaped from a lab in Wuhan, the Chinese city where the virus was first identified. The report cited several reasons for all but dismissing that possibility.
It said that such laboratory accidents are rare, that the labs in Wuhan were well-managed and there is no record of viruses closely related to the coronavirus in any laboratory before December 2019.
The report is based largely on a visit by a WHO team of international experts to Wuhan. The mission was never meant to identify the exact natural source of the virus, an endeavour that typically takes years. For instance, more than 40 years of study has still failed to pinpoint the exact species of bat that is the natural reservoir of Ebola.
In the draft obtained by the AP, the researchers listed four scenarios in order of likelihood for the emergence of the new coronavirus. Topping the list was transmission from bats through another animal, which they said was likely to very likely. They evaluated direct spread from bats to humans as likely, and said that spread to humans from the packaging of "cold-chain" food products was possible but not likely.
That last possibility was previously dismissed by the WHO and the US Centers for Disease Control and Prevention but researchers on this mission have taken it up again, further raising questions about the politicisation of the study since China has long pushed the theory.
While it's possible an infected animal contaminated packaging that was then brought to Wuhan and infected humans, the report said the probability is very low.
Mark Woolhouse, an epidemiologist at the University of Edinburgh, said even that "very low probability" was an overstatement. "There's no compelling evidence of people actually being infected through packaging," he said, calling the theory "far-fetched".
Woolhouse said it was possible the source of COVID-19 might never be identified.
"The emergence of a new [disease] is always a sequence of unlikely events," he said. "It's hard to be definitive and rule anything out." But, he said most scientists agree that bats are the most likely source.
Bats are known to carry coronaviruses and, in fact, the closest relative of the virus that causes COVID-19 has been found in bats.
The report said highly similar viruses have been found in pangolins, a scaly anteater prized in traditional Chinese medicine, but scientists have yet to identify the same coronavirus in animals that has been infecting humans.
The AP received the draft copy yesterday from a Geneva-based diplomat from a WHO member country. It wasn't clear whether the report might still be changed prior to release, though the diplomat said it was the final version. A second diplomat confirmed getting the report too. Both refused to be identified because they were not authorised to release it ahead of publication.
