Shi Zhengli, a leading virologist, became known as “Bat Woman” for her work on coronaviruses. She has spent decades studying bat-borne diseases, tracing their origins, and analyzing their potential risks. Her research played a key role in identifying threats like SARS and COVID-19, leading to crucial scientific discoveries. Over the years, her work has sparked both praise and controversy, with some recognizing her as a hero in virus research. Many credit her with groundbreaking insights into virus evolution, while others question the risks involved in studying such dangerous pathogens. Regardless of public opinion, Shi’s work has shaped global understanding of coronaviruses and their potential to cause pandemics.
The coronavirus pandemic thrust Shi into an international spotlight, intensifying debates about her work. As head of a team studying bat coronaviruses at the Wuhan Institute of Virology (WIV), she faced accusations about the origins of SARS-CoV-2. Some speculated that the virus accidentally escaped from her lab—a claim promoted by U.S. President Donald Trump. Others suggested it could have been engineered. Shi has strongly denied these allegations, emphasizing that her team had never encountered SARS-CoV-2 before the outbreak. She insists that misinformation surrounding her work has disrupted her research and personal life.
Early Fascination with Bats
Shi’s journey into virology began with her academic studies in China and abroad, where she specialized in microbiology. She joined the Wuhan Institute of Virology in 2004, a pivotal moment that set her on the path to studying bat-borne diseases. Her interest in bats deepened after the SARS outbreak, which demonstrated the devastating potential of coronaviruses. Unlike many scientists who focused on human and animal transmission, Shi believed bats carried a vast and largely unknown reservoir of viruses. Determined to explore this field, she embarked on research expeditions, often traveling to remote locations. Her findings suggested that bats harbored an extensive collection of pathogens, some with the ability to jump to humans, making them a key focus in pandemic prevention efforts.
Shi studied at Wuhan University before earning a Ph.D. at the University of Montpellier II in France. Initially, her research focused on viruses affecting shrimp and crabs, but her career took a dramatic turn in 2005. She collaborated with scientists from China, Australia, and the United States, publishing a groundbreaking study in Science. This paper provided the first evidence that bats harbored coronaviruses closely related to SARS, confirming their role as viral reservoirs.
Tracing the Origins of SARS
After SARS emerged in 2002, Shi and her team focused on finding its source, which remained a mystery for years. They collected thousands of samples from bats across China, hoping to identify a close relative of the SARS virus. After years of painstaking research, they discovered bat coronaviruses that shared significant genetic similarities with SARS. This breakthrough confirmed that bats were the original hosts of the virus, while intermediate animals likely facilitated its jump to humans. The discovery was crucial in understanding how coronaviruses evolve and spill over into new species. Her work laid the foundation for future studies on emerging infectious diseases, emphasizing the need to monitor bat populations for potential viral threats. The research also contributed to improved public health measures, aimed at preventing another SARS-like outbreak.

Dangerous Expeditions into Bat Caves
Shi and her team ventured into remote caves filled with bat colonies, often working under extreme conditions. These expeditions required navigating rugged terrain, squeezing into tight spaces, and handling unpredictable wildlife. They collected fecal, saliva, and blood samples, which they analyzed in the lab to identify new pathogens. Protective suits, gloves, and strict biosafety protocols were essential to avoid potential infection from unknown viruses. Over the years, Shi and her colleagues identified hundreds of coronaviruses in bats, some of which showed the ability to bind to human cells. These discoveries raised alarms about the potential for future pandemics, as some viruses appeared capable of direct human transmission. Her work underscored the importance of proactive surveillance in disease prevention, urging governments to invest in early detection efforts.
The Discovery of New Coronaviruses
Shi’s research led to the discovery of a wide variety of coronaviruses, many of which had significant pandemic potential. Her studies showed that some bat viruses could infect human cells without needing an intermediate animal host. This revelation challenged previous assumptions about virus transmission and raised concerns about zoonotic spillover. By closely analyzing these viruses, her team identified key genetic markers that influenced their infectiousness. This research became even more critical when COVID-19 emerged in 2019, as Shi’s earlier findings helped scientists understand its genetic structure. The knowledge gained from studying these viruses enabled researchers to develop vaccines and treatments more rapidly. Her work emphasized the importance of global cooperation in virus research, as emerging diseases can spread across borders within weeks.
The Role of Wuhan’s High-Security Lab
Shi worked at the Wuhan Institute of Virology, home to one of China’s most advanced biosafety labs. The facility specializes in studying highly infectious diseases, including coronaviruses and other deadly pathogens. Her team used genetic sequencing, molecular biology, and virus isolation techniques to analyze the behavior of various coronaviruses. Their research aimed to predict and prevent new outbreaks by identifying viruses with pandemic potential before they reached humans. Some critics speculated that her lab was linked to COVID-19’s origins, fueling debates about laboratory safety. However, no scientific evidence has supported these claims, and Shi has repeatedly defended her research. She has emphasized that WIV had never cultured SARS-CoV-2 and that no staff or students tested positive for the virus, challenging speculation that it leaked from the lab.
The COVID-19 Pandemic and Global Scrutiny
When COVID-19 emerged, Shi’s research took on unprecedented significance as the world raced to understand the virus. Scientists analyzed its genetic structure and searched for its origins, with Shi’s past research offering crucial insights. Studies showed that SARS-CoV-2 shared significant similarities with bat coronaviruses her team had previously identified. As the pandemic spread, Shi found herself at the center of intense scrutiny. Some praised her foresight in warning about coronavirus risks, while others questioned whether her lab played a role in the outbreak. The Chinese government and international health organizations investigated the matter, but no conclusive evidence linked the virus to her research. Shi remained focused on fighting misinformation, emphasizing the need for scientific collaboration in pandemic response efforts. Her contributions helped shape early containment strategies, diagnostic tests, and vaccine development.
Controversy and Conspiracy Theories
As the pandemic unfolded, Shi and her lab faced mounting scrutiny from international media, politicians, and the public. Some theories suggested that a lab accident was responsible for the outbreak, leading to intense debates. Shi dismissed these allegations as baseless, stating that her team followed strict biosafety protocols. Scientists worldwide examined the virus’s genetic origins, with most concluding that natural spillover from animals was the most likely cause. Shi was particularly frustrated when the U.S. National Institutes of Health (NIH) terminated a research grant for bat virus studies at WIV, calling the decision “absolutely absurd.” Despite setbacks, she has continued her work, stressing that the origins of SARS-CoV-2 require further investigation.
The Legacy of China’s ‘Bat Woman’
Shi Zhengli’s work has left a lasting impact on the study of infectious diseases. Her research has deepened global understanding of coronaviruses, helping to identify and mitigate viral threats. Despite facing criticism, she remains a respected figure in virology, with her discoveries influencing public health policies. The knowledge gained from her studies has contributed to vaccine development, disease surveillance, and outbreak prevention strategies. Her legacy will continue to shape virus research for generations to come, as scientists build on her findings. In a world increasingly threatened by emerging diseases, her work serves as a reminder of the importance of scientific exploration and preparedness.
