A World Health Organization crew is leaving China on Wednesday after gaining some new insights into the origins of the coronavirus pandemic that has now killed greater than 2.3 million individuals worldwide — however with the key questions nonetheless unanswered.
 
The go to was politically delicate for China — which is worried about any allegations it did not deal with the preliminary outbreak correctly — and has been intently watched around the globe.
 
Team member Peter Daszak sounded an upbeat word on arriving on the airport on the finish of the four-week journey to the central Chinese metropolis of Wuhan, the place the primary COVID-19 circumstances have been detected in December 2019.
 
“We have clear leads on what the next steps should be,” he said. “We know a lot more after the work that’s been done.”
 
The crew’s main conclusions appeared to substantiate what most researchers had already surmised in regards to the virus. The go to was by no means anticipated to definitively pinpoint the origin of the pandemic — an endeavor that, based mostly on others, may take years.
 
Here’s a take a look at the theories the crew explored throughout their go to:
 
THE BATS
 
The mission to Wuhan didn’t change a significant concept about the place the virus got here from. Scientists suppose bats are the more than likely carriers, and that they handed it on to a different animal, which handed it on to people. While there are different prospects — a bat may have contaminated a human instantly, as an illustration — the trail by a second animal stays the more than likely situation, in accordance with the WHO crew and its Chinese counterparts. The query is what animal and the place.
 
THE MARKET
 
The Huanan Seafood Market, which had a cluster of circumstances initially of the outbreak, was initially suspected because the place the place individuals first grew to become contaminated. The discovery of earlier circumstances has all however dominated out that concept, however researchers nonetheless need to understand how this early cluster occurred.
 
The market dealt primarily in frozen seafood but additionally bought domesticated wildlife. That included rabbits, that are identified to be prone to the virus, and bamboo rats and ferret badgers, that are suspected of being prone. At the WHO mission’s closing information convention Tuesday, one crew member mentioned a few of these animals have been traced to farms or merchants in areas which are residence to bats that carry the virus that’s the closest identified relative of the one which causes COVID-19.
 
The virus may even have been launched to the market by an contaminated particular person. Chinese well being officers word that solely surfaces on the market examined optimistic for the virus, not any of the animal merchandise. A Chinese official mentioned Tuesday that it seems there have been circumstances elsewhere in Wuhan across the identical time because the market cluster, so the switch of the virus from animals to people may have occurred elsewhere.
 
THE LAB
 
The conclusion of the Chinese and worldwide consultants was that this can be very unlikely the virus leaked from the Wuhan Institute of Virology, a lab with an in depth assortment of virus samples. Former U.S. President Donald Trump and officers in his administration have been amongst those that floated that chance — prompting indignant denials from China. And most consultants have lengthy been skeptical of it.
 
In making its willpower, the crew mentioned that such leaks are extraordinarily uncommon and there isn’t any proof the virus existed in that lab or any lab anyplace on this planet when the pandemic started. It additionally reviewed security protocols on the institute, main the crew to conclude “it was very unlikely that anything could escape from such a place,” WHO crew chief Peter Ben Embarek mentioned.
 
THE COLD CHAIN
 
The joint investigation left open the likelihood that the virus may have been unfold to people by frozen meals merchandise, a little bit of a shock as international consultants have usually performed down the danger.
 
It’s a concept that has been extensively promoted by Chinese officers, who’ve detected the virus on imported frozen meals packaging and seized on that to counsel the virus may have come to China from overseas.
 
WHO crew member Marion Koopmans famous that it nonetheless would not reply the query of the place the virus got here from initially. “Its not the cold chain by itself, that cannot be,” she said at the airport. “The virus has to come from somewhere.”
 
THE DATA
 
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 individuals they wished to. In the top, they appeared glad with the preparations, at the least of their public feedback. Team 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 introduced to her. But she mentioned that may be true in most nations.
