Dr. Paul Wambura has spent more than two decades studying bats, but the Kenyan wildlife biologist finds himself increasingly at odds with a familiar narrative: that bats are disease vectors we should fear and eliminate. As the Democratic Republic of Congo battles yet another Ebola outbreak—this time caused by the Bundibugyo strain, for which no approved vaccines or treatments yet exist—bats have once again become targets of public suspicion and culling campaigns. But Wambura's research points to a more complicated truth: the scientific evidence linking bats to Ebola remains inconclusive, and destroying them may cause far greater ecological harm than the diseases they're blamed for carrying.
The pattern is well-documented. During the COVID-19 pandemic, bat colonies were burned out of caves and roost sites destroyed across India, Peru, Cuba, Rwanda, and Indonesia. People acted on fear and incomplete information, driven by media narratives that often go beyond what science actually supports. "When people state categorically that bats cause Ebola, they are going beyond what the science currently supports," Wambura explains. "Much of that remains speculation rather than established fact."
What does the evidence actually show? Researchers have found antibodies in some bat species, a discovery that sounds damning until you understand what antibodies mean: they indicate exposure to a pathogen, not that the species is the source of disease. Thousands of bats have been sampled and tested since major Ebola outbreaks ravaged West and Central Africa. Despite these extensive efforts, no scientist has conclusively identified bats as the natural reservoir for Ebola. "We still do not know with certainty which animal species serves as the natural reservoir for Ebola," Wambura notes. The virus's origin remains a genuine mystery.
The consequences of this misplaced blame are severe and tangible. Bats are the second-largest group of mammals after rodents, making up roughly 25 percent of all mammal species. They are ecological keystone species—remove them, and entire ecosystems begin to collapse. Many bat species consume enormous quantities of insects each night, controlling crop pests naturally and pollinating plants that feed both wildlife and humans. When communities destroy bat roosts out of fear, they lose these essential services while gaining nothing in disease prevention.
Wambura's broader point challenges the very framing of the question. The real issue is not bats themselves but habitat destruction and human encroachment into wild spaces. When forests shrink and ecosystems fragment, contact between humans and wildlife intensifies—creating exactly the conditions where zoonotic diseases are more likely to jump species. The solution, he argues, is not fear-driven persecution but understanding: better science, better habitat protection, and recognition that bats, like many animals, naturally carry pathogens without necessarily causing outbreaks.
"The solution is not fear," Wambura insists. It's an appeal for perspective in a moment when panic has driven policy before. As the DRC works to contain this outbreak and develop treatments, the world has an opportunity to stop blaming an entire order of animals and start protecting the ecosystems they sustain.
