The Lab-Leak Theory: Inside the Fight to Uncover COVID-19’s Origins

illes Demaneuf is a data scientist with the Bank of New Zealand in Auckland. He was diagnosed with Asperger’s Syndrome ten years ago, and believes it gives him a professional advantage. “I’m very good at finding patterns in data, when other people see nothing,” he says.

Early last spring, as cities worldwide were shutting down to halt the spread of COVID-19, Demaneuf, 52, began reading up on the origins of SARS-CoV-2, the virus that causes the disease. The prevailing theory was that it had jumped from bats to some other species before making the leap to humans at a market in China, where some of the earliest cases appeared in late 2019. The Huanan wholesale market, in the city of Wuhan, is a complex of markets selling seafood, meat, fruit, and vegetables. A handful of vendors sold live wild animals—a possible source of the virus.

That wasn’t the only theory, though. Wuhan is also home to China’s foremost coronavirus research laboratory, housing one of the world’s largest collections of bat samples and bat-virus strains. The Wuhan Institute of Virology’s lead coronavirus researcher, Shi Zhengli, was among the first to identify horseshoe bats as the natural reservoirs for SARS-CoV, the virus that sparked an outbreak in 2002, killing 774 people and sickening more than 8,000 globally. After SARS, bats became a major subject of study for virologists around the world, and Shi became known in China as “Bat Woman” for her fearless exploration of their caves to collect samples. More recently, Shi and her colleagues at the WIV have performed high-profile experiments that made pathogens more infectious. Such research, known as “gain-of-function,” has generated heated controversy among virologists.
