Exhaustive account of the COVID lab leak controversy (Shi Zhengli, China's bat woman)

Meet the scientist at the center of the covid lab leak controversy

EXCERPT: . . . Inside the car, Peter Daszak—a disease ecologist and president of the EcoHealth Alliance, a New York-based nonprofit that works with scientists around the world to study viruses in wildlife—was filming the scene on his cell phone.

He was a member of the WHO team, and when we’d spoken the week before, he'd cautioned that the Wuhan trip was just a first step in trying to figure out where covid-19 came from. “It can take years or even decades to find the cause of a new infectious disease,” said Daszak, who has collaborated with the Wuhan Institute of Virology for more than 15 years and is now himself caught up in the debate over the disease’s origins. “Sometimes we just never know.”

But the world wanted quick answers.

The institute holds a critical place in the story of the covid-19 pandemic. A leading center for coronavirus research, it was the first facility to isolate the new virus, and the first to sequence its genome. One of its labs, led by virologist Shi Zhengli, focuses on coronaviruses that live in bats, and has spent years sequencing viral genomes, isolating live viruses, and—through genetic mixing and matching—trying to understand how they may evolve to gain the ability to infect humans. Over the past 18 years, her team has collected more than 20,000 samples from bat colonies across China.

Shi’s work, which has earned her the nickname China’s bat woman, has been at the center of controversy. Some have suggested that her bat samples could be the source of the covid-19 virus, which scientists call SARS-CoV-2. They have claimed that the virus could have hitched a ride to Wuhan by infecting one of her team members in their fieldwork collecting samples from bats. Or, some speculate, the live viruses her team cultured in the lab, including—more worryingly—the ones they created by genetic tinkering, could be the source of the pandemic.

All eyes were on the WHO, the leading international public health agency, to probe covid-19’s origins. The team’s mission was to examine when and where the outbreak had started and how the new virus crossed over to humans. The report, which was released last March, concluded it was “extremely unlikely” that covid-19 could have been caused by a lab accident. The situation the team ranked most likely was that it had jumped from bats to humans via some intermediary animal. Their results, supported by research published in peer-reviewed journals and by ongoing studies, suggest that the pandemic probably started at the Huanan Seafood Wholesale Market in central Wuhan, where live mammals were sold and where most of the early covid-19 cases emerged.

Not everybody agrees, but the majority of virologists and infectious-disease experts, especially those working directly on the origins question, lean toward that theory, barring the emergence of new evidence that persuades them otherwise.

Spillover from animals to humans “was how almost every major epidemic got started in the past decades,” says Shi’s longtime collaborator Linfa Wang, an expert on emerging infectious diseases at the Duke–National University of Singapore Medical School and a member of the WHO team that in 2003 investigated the origins of SARS, a deadly infectious disease caused by a coronavirus now known as SARS-CoV-1. That illness sickened 8,000 people worldwide and killed nearly 800 between 2002 and 2004. “It’s a common and well-documented pathway,” he says.

But one year after the WHO’s visit to Wuhan, the disease detectives have yet to find the guilty animal or other indisputable evidence of natural origins. Critics also question the conclusion of the agency’s mission team partly because one of its members, Daszak, who is a prominent advocate of the natural origins theory, has potential conflicts of interest. Speculation over the possibility of a lab accident has surged. Inflaming the suspicions are concerns over biosafety procedures at the Wuhan lab, political tensions between China and the US, and a general sense that the Chinese government is not to be trusted.

Scientists like David Relman, an expert on microbiology and biosecurity at Stanford University, are dismayed at the way the lab leak theory has been dismissed. He helped organize a group of 18 scientists to sign a letter published in Science last May calling for further investigation of a possible accident. (At least two of those involved later sought to distance themselves from the letter after seeing how it had been used to promote the lab leak theory.) Soon afterwards, President Joe Biden directed the US intelligence community to intensify its probe into the pandemic’s origins. The declassified report released in October shows that it reached no firm conclusion.

In December 2020, a month before the WHO visit, I too embarked on a search for answers. I talked to dozens of top scientists and biosafety experts worldwide. I spent six weeks in Wuhan, where I interviewed Shi and her team for a total of more than 40 hours. I had a private meeting with three members of the WHO mission. I visited the Wuhan Institute of Virology half a dozen times, often on the spur of the moment, and went with the scientists on a virus-sampling trip to a bat cave. By trying to understand the process and context of Shi’s work—and to find out who she was—I wanted to learn what role, if any, China’s bat woman had in the origins of covid-19.

Probing covid-19’s origins will not only help us understand how coronaviruses work but shine a bright light on the human behaviors—including the types of scientific research—that risk causing a pandemic in the future.

Like the WHO team, I have not gone through Shi’s freezers or lab books, and therefore I cannot prove or disprove whether activities associated with her research caused the pandemic. It’s more about providing additional perspectives—having Shi and her team tell their side of the story on the record, and in the most detail to date, so that the world can better understand how this deeply entrenched controversy has come about and how we can move forward...
