Recent reports that Department of Energy and FBI officials think the COVID-19 pandemic originated with a so-called lab leak appear to have provided all the “evidence” many require. As a scientist who has led or contributed to several peer-reviewed studies that tell a very different story, I’ve looked on with amazement at the growing divide between what the science shows and what much of the public — and a minority of the intelligence community — believe. But I’ve also watched with understanding for those who still suspect a lab leak because I started there myself.
The nucleus of all lab leak conjectures — they are not a single hypothesis but a wide range of sometimes mutually exclusive speculations — was famously captured by the comedian Jon Stewart. “Oh, my God, there’s a novel respiratory coronavirus overtaking Wuhan, China — what do we do?” Stewart said during a June 2021 appearance on “The Late Show With Stephen Colbert.” “Oh, you know who we could ask: the Wuhan Novel Respiratory Coronavirus Lab. The disease is the same name as the lab!”
Stewart didn’t have the name right, but he was referring to the work of the Chinese scientist Shi Zhengli, whose lab at the Wuhan Institute of Virology does indeed study SARS-related coronaviruses from horseshoe bats, the ultimate reservoir of both the original SARS virus and SARS-CoV-2, the virus that causes COVID-19.
