A World Well being Group 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 folks worldwide — however with the most important 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 world wide.
Workforce member Peter Daszak sounded an upbeat observe 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 now have clear leads on what the subsequent steps must be,” he stated. “We all know much more after the work that’s been achieved.”
The crew’s main conclusions appeared to verify 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, primarily based on others, may take years.
Right here’s a have a look at the theories the crew explored throughout their go to:
The mission to Wuhan didn’t change a serious principle about the place the virus got here from. Scientists suppose bats are the probably carriers, and that they handed it on to a different animal, which handed it on to people. Whereas there are different potentialities — a bat may have contaminated a human instantly, for example — the trail via a second animal stays the probably situation, based on the WHO crew and its Chinese language counterparts. The query is what animal and the place.

The Huanan Seafood Market, which had a cluster of circumstances at the beginning of the outbreak, has lengthy been steered as a attainable 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 crew member stated 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 may put renewed focus available on the market. Chinese language well being officers have downplayed the market’s function, noting that solely surfaces on the market examined constructive for the virus, not any of the animal merchandise. A Chinese language official stated Tuesday that it seems there have been circumstances elsewhere in Wuhan across the similar time because the market cluster, so it stays attainable 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 in depth assortment of virus samples. Former U.S. President Donald Trump and officers in his administration had been amongst those that floated that chance — prompting indignant denials from China. And most specialists have lengthy been skeptical of it.

In making its willpower, the crew stated that such leaks are extraordinarily uncommon and there’s no proof the virus existed in that lab or any lab wherever on the planet when the pandemic started. It additionally reviewed security protocols on the institute, main the crew to conclude “it was impossible that something may escape from such a spot,” WHO crew chief Peter Ben Embarek stated.
THE COLD CHAIN
The joint investigation left open the chance that the virus may have been unfold to people via frozen meals merchandise, a little bit of a shock as international specialists have typically 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 recommend the virus may have come to China from overseas.

WHO crew 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’t be,” she stated 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 wished to. In the long run, they appeared happy with the preparations, at the very least of their public feedback. Workforce member Thea Koelsen Fischer stated she didn’t get to see uncooked knowledge and needed to depend on an evaluation of the info that was introduced to her. However she stated that will be true in most nations.
