The Last Week Tonight with John Oliver February 15th episode shared misguided speculations about bats. Here is Merlin’s public letter to John Oliver. We don’t have his email address, so we’re counting on you to help get his attention. No shade, John, we understand the topic is muddy. We simply want the opportunity to set the record straight!

Given your reputation for integrity and fearless candor, several of your loyal followers have asked me to help you better understand disease risks from bats. Why me? Because, as one of the world’s most experienced bat researchers, I’ve handled hundreds of species worldwide for 60 years, often surrounded by millions in caves. I’ve also led successful conservation efforts internationally for more than 40 years. My experience and photographs are used worldwide, including in National Geographic articles, to share the truth about bats through my organization, Merlin Tuttle’s Bat Conservation. Here’s a clip from my appearance on David Letterman decades ago; I have been leading efforts to educate humans about bats my entire career.
I, and hundreds of others who study bats, have spent whole careers working with them unprotected against any of the so-called emerging diseases about which we’re now warned. And we’re still healthy. We’re also aware that millions of people visit and work in caves annually without causing disease outbreaks.
Thus, we question the sanity of warnings of extreme risks to visitors of tour caves where a bat could purportedly cause a deadly pandemic by defecating on them. There is no proof that such an event has ever occurred. And warning of the possibility is like warning of death from a falling spacecraft, possible but extremely unlikely.
I appreciate your mention of the far greater risks from industrial meat production and your comments on the essential contributions of bats to a healthy planet, but this is not enough to cultivate understanding and put risks in perspective. For the record, unlike rodents who are overpopulating due to the loss of predators, bats are extraordinarily vulnerable to extinction and already in alarming decline.
Exaggerated fear is the greatest cause of human intolerance and killing of bats. Unfortunately, sensational speculation, linking them to scary diseases, sells headline media stories and large grants. Virus hunting, typically linked to bats, has been shown to be an ineffective means of pandemic prevention. However, because bats are the easiest mammals to sample, and have few defenders, they have become tempting victims. Your guest failed to mention that, for anyone who simply doesn’t handle bats, the risk of contracting any disease from one is minuscule. In fact, millions of bats share cities with people from America to Africa and Australia without causing disease outbreaks. As our human population continues to expand, we inescapably must learn to live in harmony with nature.
Although well-intended, the following documented points are too often distorted or ignored in sensational media coverage. I’d be more than happy to assist you and your staff in balancing the story.
- Bats harbor no more viruses than other animals 1.
- Claims of disease from bats are often based on poorly supported speculation 2.
- Claims of 96% genomic similarity between viruses are meaningless and misleading 3,4.
- Promises that can’t be kept are misdirecting billions of dollars to virus hunting that is counterproductively biased toward bats and better spent on other health priorities 5,6, 7.
- Bats have an undeniable history of living with humans without causing disease outbreaks 8.
- There is a long history of lucrative, but exceptionally harmful, exploitation of disease exaggerations against bats 9.
- Fear of bats leads to intolerance and killing 9,10.
- Asking people to conserve bats because they are beneficial, while failing to counter exaggerated fear, is unlikely to improve conservation success 10.
- Ebola was first speculated to come from fruit bats, then insectivorous bats, but more recently it was admitted that no source has been found despite extensive efforts 11, 12.
- It cannot be stated strongly enough that Ebola, SARS, MERS, and SARS-CoV-2 have not been isolated from a bat despite frequent attempts.
Also, here’s a recent video sponsored by the U.S. National Park Service about putting bat fears in perspective. Thank you for your time, I hope to hear from you.
