A World Well being Group workforce is leaving China on Wednesday after gaining some new insights into the origins of the coronavirus pandemic that has now killed greater than 2.three million folks worldwide — however with the foremost questions nonetheless unanswered.
The go to was politically delicate for China — which is anxious about any allegations it didn’t deal with the preliminary outbreak correctly — and has been carefully watched all over the world.
Workforce member Peter Daszak sounded an upbeat notice on arriving on the airport on the finish of the four-week journey to the central Chinese language metropolis of Wuhan, the place the primary COVID-19 circumstances had been detected in December 2019.
“We’ve got clear leads on what the subsequent steps needs to be,” he mentioned. “We all know much more after the work that’s been accomplished.”
The workforce’s main conclusions appeared to substantiate what most researchers had already surmised concerning the virus. The go to was by no means anticipated to definitively pinpoint the origin of the pandemic — an enterprise that, primarily based on others, might take years.
Right here’s a take a look at the theories the workforce explored throughout their go to:
The mission to Wuhan didn’t change a significant principle about the place the virus got here from. Scientists suppose bats are the most certainly carriers, and that they handed it on to a different animal, which handed it on to people. Whereas there are different prospects — a bat might have contaminated a human immediately, as an illustration — the trail by means of a second animal stays the most certainly situation, in keeping with the WHO workforce and its Chinese language counterparts. The query is what animal and the place.
1 12 months later: Wuhan declares victory over COVID-19
The Huanan Seafood Market, which had a cluster of circumstances initially of the outbreak, has lengthy been steered as a doable place people first turned contaminated. The market dealt primarily in frozen seafood but in addition offered domesticated wildlife. That included rabbits, that are identified to be vulnerable to the virus, and bamboo rats and ferret badgers, that are suspected of being vulnerable. On the WHO mission’s closing information convention Tuesday, one workforce member mentioned a few of these animals have been traced to farms or merchants in areas which might be residence to bats that carry the virus that’s the closest identified relative of the one which causes COVID-19.
That discovering might put renewed focus in the marketplace. Chinese language well being officers have downplayed the market’s position, noting that solely surfaces on the market examined constructive for the virus, not any of the animal merchandise. A Chinese language official mentioned Tuesday that it seems there have been circumstances elsewhere in Wuhan across the similar time because the market cluster, so it stays doable the switch of the virus from animals to people occurred elsewhere.
The conclusion of the Chinese language and worldwide specialists was that this can be very unlikely the virus leaked from the Wuhan Institute of Virology, a lab with an intensive assortment of virus samples. Former U.S. President Donald Trump and officers in his administration had been amongst those that floated that chance — prompting offended denials from China. And most specialists have lengthy been skeptical of it.

In making its dedication, the workforce mentioned that such leaks are extraordinarily uncommon and there’s no proof the virus existed in that lab or any lab anyplace on the earth when the pandemic started. It additionally reviewed security protocols on the institute, main the workforce to conclude “it was most unlikely that something might escape from such a spot,” WHO workforce chief Peter Ben Embarek mentioned.
THE COLD CHAIN
The joint investigation left open the likelihood that the virus might have been unfold to people by means of frozen meals merchandise, a little bit of a shock as international specialists have usually performed down the chance.
It’s a principle that has been broadly promoted by Chinese language officers, who’ve detected the virus on imported frozen meals packaging and seized on that to counsel the virus might have come to China from overseas.

WHO workforce member Marion Koopmans famous that it nonetheless wouldn’t reply the query of the place the virus got here from initially. “Its not the chilly chain by itself, that can not be,” she mentioned on the airport. “The virus has to come back from someplace.”
The mission has been dogged by questions on how a lot freedom China would give the researchers to go to the locations and discuss to the folks they needed to. Ultimately, they appeared glad with the preparations, at the very least of their public feedback. Workforce member Thea Koelsen Fischer mentioned she didn’t get to see uncooked knowledge and needed to depend on an evaluation of the information that was offered to her. However she mentioned that may be true in most nations.
