WHO-China report claims coronavirus lab leak ‘extraordinarily unlikely,’ suggests animal-human transmission

A joint WHO-China examine on the origins of COVID-19 says that transmission of the virus from bats to people by way of one other animal is the almost certainly state of affairs and {that a} lab leak is “extraordinarily unlikely,” in accordance with a draft copy obtained by The Related Press.

The findings provide little new perception into how the virus started to unfold across the globe and lots of questions stay unanswered, although that was as anticipated. However the report did present extra element on the reasoning behind the researchers’ conclusions. The workforce proposed additional analysis in each space besides the lab leak speculation.

The report’s launch has been repeatedly delayed, elevating questions on whether or not the Chinese language aspect was making an attempt to skew the conclusions to forestall blame for the pandemic falling on China. A World Well being Group official stated late final week that he anticipated it could be prepared for launch “within the subsequent few days.”


The AP obtained a duplicate on Monday from a Geneva-based diplomat from a WHO-member nation. It wasn’t clear whether or not the report may nonetheless be modified previous to launch, although the diplomat stated it was the ultimate model. A second diplomat confirmed getting the report too. Each refused to be recognized as a result of they weren’t licensed to launch it forward of publication.

The WHO didn’t instantly reply to emails and cellphone calls in search of remark.

The researchers listed 4 eventualities so as of chance for the emergence of the coronavirus named SARS-CoV-2. Topping the checklist was transmission from bats by way of one other animal, which they stated was more likely to very probably. They evaluated direct unfold from bats to people as probably, and stated that unfold by way of “cold-chain” meals merchandise was doable however unlikely.


Bats are identified to hold coronaviruses and, in reality, the closest relative of the virus that causes COVID-19 has been present in bats. Nonetheless, the report says that “the evolutionary distance between these bat viruses and SARS-CoV-2 is estimated to be a number of many years, suggesting a lacking hyperlink.”

It stated extremely related viruses have been present in pangolins, that are one other type of mammal, but additionally famous that mink and cats are inclined to the COVID-19 virus, suggesting they may very well be carriers, too.

The report relies largely on a go to by a WHO workforce of worldwide specialists to Wuhan, the Chinese language metropolis the place COVID-19 was first detected, from mid-January to mid-February.

Peter Ben Embarek, the WHO knowledgeable who led the Wuhan mission, stated Friday that the report had been finalized and was being fact-checked and translated.

“I count on that within the subsequent few days, that complete course of can be accomplished and we can launch it publicly,” he stated.


The draft report is inconclusive on whether or not the outbreak began at a Wuhan seafood market that had one of many earliest clusters of circumstances in December 2019.

The invention of different circumstances earlier than the Huanan market outbreak suggests it might have began elsewhere. However the report notes there may have been milder circumstances that went undetected and that may very well be a hyperlink between the market and earlier circumstances.

“No agency conclusion due to this fact in regards to the position of the Huanan market within the origin of the outbreak, or how the an infection was launched into the market, can at the moment be drawn,” the report stated.

The market was an early suspect as a result of some stalls bought a spread of animals — and a few questioned if that they had introduced the brand new virus to Wuhan. The report famous {that a} vary of animal merchandise — together with every part from bamboo rats to deer, usually frozen — have been bought on the market, as have been dwell crocodiles.

Because the pandemic unfold globally, China discovered samples of the virus on the packaging of frozen meals coming into the nation and, in some circumstances, have tracked localized outbreaks to them.


The report stated that the chilly chain, as it’s identified, could be a driver of long-distance virus unfold however was skeptical it may have triggered the outbreak. The report says the danger is decrease than by way of human-to-human respiratory an infection, and most specialists agree.

“Whereas there may be some proof for doable reintroduction of SARS-CoV-2 by way of dealing with of imported contaminated frozen merchandise in China for the reason that preliminary pandemic wave, this might be extraordinary in 2019 the place the virus was not broadly circulating,” the examine stated.

The report cited a number of causes for all however dismissing the likelihood the virus escaped from a lab in Wuhan, a speculative idea that was prompt and promoted by former U.S. President Donald Trump amongst others.

It stated such laboratory accidents are uncommon and the labs in Wuhan engaged on coronaviruses and vaccines are well-managed. It additionally famous that there is no such thing as a file of viruses carefully associated to SARS-CoV-2 in any laboratory earlier than December 2019 and that the danger of by accident rising the virus was extraordinarily low.
