A World Health Organization team is leaving China on Wednesday after gaining some new insights into the origins of the coronavirus pandemic that has now killed more than 2.3 million people worldwide — but with the major questions still unanswered. The visit was politically sensitive for China — which is concerned about any allegations it didn’t handle the initial outbreak properly — and has been closely watched around the world. Team member Peter Daszak sounded an upbeat note on arriving at the airport at the end of the four-week trip to the central Chinese city of Wuhan, where the first COVID-19 cases were 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 team’s major conclusions seemed to confirm what most researchers had already surmised about the virus. The visit was never expected to definitively pinpoint the origin of the pandemic — an undertaking that, based on others, could take years. Here’s a look at the theories the team explored during their visit: THE BATS The mission to Wuhan did not change a major theory about where the virus came from. Scientists think bats are the most likely carriers, and that they passed it on to another animal, which passed it on to humans. While there are other possibilities — a bat could have infected a human directly, for instance — the path through a second animal remains the most likely scenario, according to the WHO team and its Chinese counterparts. The question is what animal and where. THE MARKET The Huanan Seafood Market, which had a cluster of cases at the start of the outbreak, has long been suggested as a possible place humans first became infected. The market dealt mainly in frozen seafood but also sold domesticated wildlife. That included rabbits, which are known to be susceptible to the virus, and bamboo rats and ferret badgers, which are suspected of being susceptible. At the WHO mission’s closing news conference Tuesday, one team member said some of these animals have been traced to farms or traders in regions that are home to bats that carry the virus that is the closest known relative of the one that causes COVID-19. That finding could put renewed focus on the market. Chinese health officials have downplayed the market’s role, noting that only surfaces at the market tested positive for the virus, not any of the animal products. A Chinese official said Tuesday that it appears there were cases elsewhere in Wuhan around the same time as the market cluster, so it remains possible the transfer of the virus from animals to humans happened elsewhere. THE LAB The conclusion of the Chinese and international experts was that it is extremely unlikely the virus leaked from the Wuhan Institute of Virology, a lab with an extensive collection of virus samples. Former U.S. President Donald Trump and officials in his administration were among those who floated that possibility — prompting angry denials from China. And most experts have long been skeptical of it. In making its determination, the team said that such leaks are extremely rare and there’s no evidence the virus existed in that lab or any lab anywhere in the world when the pandemic […]
