President Trump’s claim that SARS-CoV-2 was leaked from our institute totally contradicts the facts,” she added. He owes us an apology.”Shi stressed that over the past 15 years, her lab has isolated and grown in culture only three bat coronaviruses related to one that infected humans: the agent that causes severe acute respiratory syndrome (SARS), which erupted in 2003. Shi is unsure but concurs with the When the outbreak surfaced, Wuhan health officials believed the jump occurred at the Huanan Seafood Wholesale Market because many of the first known COVID-19 patients had links to it. “What I really like about Zhengli is that she is frank and honest and that just makes it easier to solve problems,” he says.After taking a blood sample, Shi Zhengli releases a fruit bat outside a cave in Guangxi province in 2004. Limiting the search at the market to “frozen” animal samples is an “obvious gap,” he says: “What were these? Aspiring Science Journalists Begin Fellowships During ‘Pivot Points in History’
The team never found SARS-CoV-2, the pandemic virus, in bats, Shi says.Andersen would like more specifics.

Shi is “is extremely driven to produce high-quality work,” Daszak says. They spread on China’s social media sites and then in the Yet the possibility that her lab had played a role worried Shi, she revealed in a March Some suspicions have focused on a naming inconsistency.
“Many groups in China are carrying out such studies,” she wrote. Based on the most recent available Pew figures, 72% of US-based AAAS members are male (compared to 50% of the public), 83% are white (compared to 60% of the public) and 72% hold a PhD or doctorate. The strength of Science and its online journal sites rests with the strengths of its community of authors, who provide cutting-edge research, … Evolutionary biologist Kristian Andersen of Scripps Research says he suspects Shi’s answers were “carefully vetted” by the Chinese government. Shi added that many years of surveillance in Hubei have never turned up bat coronaviruses close to SARS-CoV-2, which leads her to believe the jump from animals to humans happened elsewhere.Shi Zhengli’s team takes samples from bats trapped in the wild. We are tracing the origin of the virus in different directions and through multiple approaches.”Daszak supports the push for an international research effort—which he cautions could take years—and says Shi’s group should play a prominent role in it. Shi Zhengli, one of the world’s leading bat coronavirus researchers, trains staff at the Wuhan Institute of Virology on how to safely work in their new biosafety level 4 laboratory in 2017.The coronavirus pandemic has thrust virologist Shi Zhengli into a fierce spotlight.
