The mission concluded that the second hypothesis, that the virus jumped from one species to another before infecting people, is “the most likely pathway.” While the mission reported that the direct spillover and food-chain ideas needed more investigation, Ben Embarek said the team had dismissed the idea that a lab-leak hypothesis as “extremely unlikely” and said it wouldn’t be pursued any further.
But days after the presser, the remarks by Ben Embarek and the team were undercut when World Health Organization Director-General Tedros Adhanom Ghebreyesus said no hypotheses had been ruled out: “I want to clarify that all hypotheses remain open and require further study.” Where the WHO investigators go from here remains to be seen.
