The coronavirus pandemic has thrust virologist Shi Zhengli right into a fierce highlight. Shi, who’s been nicknamed “Bat Girl,” heads a bunch that research bat coronaviruses on the Wuhan Institute of Virology (WIV), within the metropolis in China the place the pandemic started, and lots of have speculated that the virus that causes COVID-19 by accident escaped from her lab—a principle promoted by U.S. President Donald Trump. Some have even recommended it might have been engineered there.

China has fully rejected such claims, however Shi (pronounced SHUH) herself has mentioned little or no publicly.

Now, Shi has damaged her silence concerning the particulars of her work. On 15 July, she emailed Science solutions to a sequence of written questions concerning the virus’ and the analysis at her institute. In them, Shi hit again at hypothesis that the virus leaked from WIV. She and her colleagues found the virus in late 2019, she says, in samples from sufferers who had a pneumonia of unknown . “Earlier than that, we had by no means been in touch with or studied this virus, nor did we all know of its existence,” Shi wrote.

“U.S. President ’s declare that SARS-CoV-2 was leaked from our institute completely contradicts the information,” she added. “It jeopardizes and impacts our tutorial work and private life. He owes us an .”

Shi harassed that over the previous 15 years, her lab has remoted and grown in tradition solely three bat coronaviruses associated to 1 that contaminated people: the agent that causes extreme acute respiratory syndrome (SARS), which erupted in 2003. The greater than 2000 different bat coronaviruses the lab has detected, together with one that’s 96.2% similar to SARS-CoV-2—which implies they shared a typical ancestor many years in the past—are merely genetic sequences that her group has extracted from fecal samples and oral and anal swabs of the animals. She additionally famous that the entire employees and college students in her lab have been not too long ago examined for SARS-CoV-2 and everybody was unfavorable, difficult the notion that an contaminated particular person in her group triggered the pandemic.

Shi was notably chagrined concerning the 24 April resolution by the U.S. Nationwide Institutes of Well being (NIH), made on the White Home’s behest, to ax a grant to the EcoHealth Alliance in New York Metropolis that included bat virus analysis at WIV. “We don’t perceive [it] and really feel it’s completely absurd,” she mentioned.

Science shared Shi’s s—obtainable right here in full (PDF)—with a of main researchers in different nations. “It’s a giant contribution,” says Daniel Lucey of Georgetown College, an outbreak specialist who blogs about SARS-CoV-2 points. “There are a of new information that I wasn’t conscious of. It’s very thrilling to listen to this straight from her.”

Shi’s solutions have been coordinated with public data staffers on the Chinese language Academy of Sciences, of which WIV is a component, and it took her 2 months to arrange them. Evolutionary biologist Kristian Andersen of Scripps Analysis says he suspects Shi’s solutions have been “rigorously vetted” by the Chinese language authorities. “However they’re all logical, real, and persist with the science as one would have anticipated from a world-class scientist and one of many main specialists on coronaviruses,” Andersen says.

Nevertheless, Richard Ebright, a molecular biologist at Rutgers College, New Brunswick, who from the early days of the pandemic has urged that an investigation look into the that SARS-CoV-2 entered people by a laboratory accident, was decidedly unimpressed. “Most of those solutions are formulaic, virtually robotic, reiterations of statements beforehand made by Chinese language authorities and state media,” Ebright says.

Shi’s s come at a time when questions on how the pandemic started are more and more inflicting worldwide tensions. regularly calls SARS-CoV-2 “the China virus” and has mentioned China might have stopped the pandemic in its tracks. China, for its half, has added an additional layer of assessment for any researchers who need to publish papers on the pandemic’s s and has asserted with out proof that SARS-CoV-2 could have ated in america.Requires an impartial, worldwide probe into the questions are mounting, and China has invited two researchers from the World Well being Group to go to the nation to debate the scope and scale of a mission. They’re now in China working by these particulars. Lucey says Shi’s solutions to Science’s questions might assist information the investigation group. (Listed below are associated questions Science has recommended the mission ought to tackle.)

A virus hunter

Peter Daszak of the EcoHealth Alliance has labored with Shi for greater than 15 years. He describes her as social, open, and one thing of a goodwill ambassador for China at worldwide conferences, the place she converses in each French and English. (She’s additionally a famend singer of Mandarin folks songs.) “What I actually like about Zhengli is that she is frank and trustworthy and that simply makes it simpler to resolve issues,” he says.

After taking a blood pattern, Shi Zhengli releases a fruit bat exterior a collapse Guangxi province in 2004. The work resulted in a Science paper that may grow to be a turning level in her profession.

Born in Henan province in central China, Shi studied at Wuhan College and WIV, then earned a Ph.D. in France on the College of Montpellier II. She returned to WIV in 2000. Initially, the overwhelming majority of her analysis targeted on viruses in shrimp and crabs, and her papers all appeared in specialty publications comparable to Virologica Sinica and the Journal of Fish Illnesses.

However in 2005, a research she printed in Science with Daszak and different researchers from China, Australia, and america turned a turning level in her profession. The paper reported the first proof that bats harbored coronaviruses intently associated to the deadly virus that jumped from civets to people and prompted the worldwide outbreak of SARS in 2003.

With NIH funding, Daszak has continued to work with Shi and her WIV group to ent wild animals and take samples to hunt for extra coronaviruses. They’ve printed 18 extra papers collectively about viruses found in bats and rodents. Shi is “is extraordinarily pushed to provide high-quality work,” Daszak says. “She is going to exit within the area, and will get concerned within the work, however her actual expertise are within the lab, and she or he’s among the best I’ve labored with in China, in all probability globally.”

Shi informed Science her lab was thrust into the pandemic on 30 December 2019, the day her group first obtained affected person samples. “Subsequently, we quickly carried out analysis in parallel with different home establishments, and rapidly recognized the pathogen,” she wrote.

It didn’t lengthy take for suspicions and rumors to come up. They unfold on China’s social media websites after which within the United Kingdom’s Day by day Mail and The Washington Instances within the United States. On 2 February, Shi posted a word on her personal social media web site that mentioned SARS-CoV-2 was “nature punishing the uncivilized habits and customs of people,” and she or he was keen to “guess my life that [the outbreak] has nothing to do with the lab.” Partly as a present of assist for Shi, Daszak and 26 different scientists from eight nations exterior of China printed a assertion of solidarity with Chinese language scientists and well being professionals in The Lancet in February. In a 17 March Nature paper that analyzed SARS-CoV-2’s genetic make-up, Andersen and different evolutionary biologists argued towards it being engineered in a lab.

But the that her lab had performed a task nervous Shi, she revealed in a March Scientific American profile that briefly touched on questions. “She frantically went by her personal laboratory’s data from the previous few years to test for any mishandling of experimental supplies, particularly throughout disposal,” the story mentioned. Not one of the sequences of bat viruses her lab had discovered intently matched SARS-CoV-2, the article famous. “That actually took a load off my thoughts,” she informed Scientific American. “I had not slept a wink for days.”

No accident

In her written solutions to Science, Shi defined in n element why she thinks her lab is innocent. WIV has recognized a whole bunch of bat viruses through the years, however by no means something near SARS-CoV-2, she says. Though a lot hypothesis has centered on RaTG13, the bat virus that almost all intently resembles SARS-CoV-2, variations within the sequences of the 2 viruses counsel they diverged from a typical ancestor someplace between 20 and 70 years in the past. Shi notes that her lab by no means cultured the bat virus, making an accident far much less doubtless.

Some suspicions have targeted on a naming inconsistency. In 2016, Shi described a partial sequence of a bat coronavirus that she dubbed 4991. That small a part of the genome precisely matches RaTG13, main some to invest that Shi by no means revealed the complete sequence of 4991 as a result of it truly is SARS-CoV-2. In her replies, Shi defined that 4991 and RaTG13 are one and the identical. The unique identify, she says, was for the bat itself, and her group switched to RaTG13 after they sequenced the whole virus. “We modified the identify as we wished it to mirror the time and site for the pattern assortment,” she mentioned, including that TG stands for Tongguan (the city in Yunnan province the place they trapped that bat) and 13 is brief for the yr, 2013.

That’s “a really logical rationalization,” says Edward Holmes, an evolutionary biologist on the College of Sydney who co-authored the Nature paper with Andersen. Shi’s reply additionally clarified to him why 4991 held such little curiosity to her group that they didn’t even hassle to sequence it absolutely till not too long ago: That brief genetic sequence was very completely different from SARS-CoV, the virus that prompted the 2003 SARS outbreak. “In studying this the penny dropped: In fact, they’d have been primarily excited by bat viruses intently associated to SARS-CoV, as a result of this virus emerged and prompted a human epidemic … not some random bat virus that’s extra distant,” Holmes says.

With assist from France’s Mérieux Institute, the Wuhan Institute of Virology constructed a biosafety degree four laboratory, which is used to check extremely harmful pathogens—and isn’t wanted for many coronavirus experiments.

Shi talked about a of different components that she says exonerate her lab. Their analysis meets strict biosafety lines, she mentioned, and the lab is topic to periodic inspections “by a third-party establishment approved by the federal government.” Antibody assessments have proven there’s “zero an infection” amongst institute employees or college students with SARS-CoV-2 or SARS-related viruses. Shi mentioned WIV has by no means been ordered to destroy any samples after the pandemic erupted and she or he was positive the virus didn’t come from the Wuhan Heart for Illness Management and Prevention—or one other lab within the metropolis—both: “Based mostly on each day tutorial exchanges and dialogue, I can rule out such a chance.”

Labs that presumably had strict biosafety lines have had accidents: The SARS virus escaped from a of labs after the worldwide outbreak was contained in 2003. And even when everybody within the institute examined unfavorable for the virus right now, an contaminated particular person might have left WIV months in the past. Nonetheless, Holmes says, the solutions are “a transparent, complete, and plausible account” of what occurred at WIV.

Mysterious s

However then the place did the virus come from? Shi is not sure however concurs with the scientific consensus that it ated in bats and jumped to people both straight or, extra doubtless, through an intermediate host.

When the outbreak surfaced, Wuhan well being offrs believed the bounce occurred on the Huanan Seafood Wholesale Market as a result of lots of the first identified COVID-19 sufferers had hyperlinks to it. Shi’s lab examined samples from the market and located RNA fragments from the virus in “door handles, the bottom and sewage,” she wrote—however not in “frozen animal samples.”

Nevertheless, two papers printed in late January revealed that as much as 45% of the primary confirmed sufferers—together with 4 of the 5 earliest instances—didn’t have any ties to the market, casting doubt on the speculation that it was the . Shi agrees: “The Huanan seafood market could be a crowded location the place a cluster of early novel coronavirus sufferers have been discovered.”

Researchers from WIV and Huazhong Agricultural College didn’t discover the virus in samples from farmed animals and livestock taken round Wuhan and somewhere else in Hubei province, she wrote. Shi added that a few years of surveillance in Hubei have by no means turned up bat coronaviruses near SARS-CoV-2, which leads her to consider the bounce from animals to people occurred elsewhere.

Shi Zhengli’s group takes samples from bats trapped within the wild. The group by no means discovered SARS-CoV-2, the pandemic virus, in bats, Shi says.


Andersen would really like extra specifics. Limiting the search on the market to “frozen” animal samples is an “apparent hole,” he says: “What have been these? Did they take a look at any reside animals? I’m nonetheless a bit puzzled by the assertion that the one position of the market was that it was a crowded location, but so lots of the environmental samples have been optimistic so early on.”

Shi supplied few particulars on China’s efforts to pin down the . “Many teams in China are finishing up such research,” she wrote. “We’re publishing papers and information, together with these concerning the virus’s s. We’re tracing the of the virus in several instructions and thru a of approaches.”

Daszak helps the push for a global analysis effort—which he cautions might take years—and says Shi’s group ought to play a distinguished position in it. “I hope and consider that she’s going to be capable of assist WIV and China present the world that there’s nothing to those lab escape theories, and assist us all to search out the true s of this viral pressure,” he says.

Shi ended her solutions to Science on the same word. “Over the previous 20 years, coronaviruses have been disrupting and impacting human lives and economies,” she mentioned. “Right here, I want to make an attraction to the worldwide group to strengthen worldwide cooperation on analysis into the s of rising viruses. I hope scientists all over the world can stand collectively and work collectively.”
