Bat Flash! CNN Misses the Mark

Bat Flash

Response to CNN Program “Bats—The Mystery Behind COVID-19″

6/16/2020
By Merlin Tuttle

I applaud Anderson Cooper for his attempt to improve public perceptions of bats. His program included numerous reasons why we should appreciate and protect bats. Nevertheless, producers failed to alleviate needless fear by omission of key facts and addition of misleading narratives. Such approaches unfortunately solidify needless fear and can’t be countered by simply sharing bat values. For bats to be tolerated, fear must be eliminated.

Many researchers were reported to “believe” that COVID-19 came from bats. Bats were claimed to be reservoirs for the standard litany of deadliest diseases, including Ebola, though the source of Ebola and COVID-19 remains a mystery. Bats were clearly stated to harbor more zoonotic viruses than other animals, ignoring recent research refuting such claims. Furthermore, scientists shown studying bats wore sealed suits and full-face respirator protection, sending a strong visual message of danger.

A wonderful array of positive things were said about bats, and their essential ecosystem and economic roles were emphasized. However, without putting risks in perspective, viewers were advised to respect, not fear, bats and were warned that we should protect bats or put ourselves at risk. Such approaches are high-risk for negative consequences.

Human encroachment into bat habitats was blamed for pandemic disease threats. However, it was not explained how expanding human populations could reduce pandemic risks simply by ending logging or invasion of new bat habitats. Nor was it explained how bats, restricted to their protected areas apart from where we live and grow crops, could possibly continue to shield us from mosquitoes in our yards or pests that attack our crops. 

Missing elements were conspicuous by their absence. There was no mention of the fact that millions of bats share cities with humans in America, Africa, Asia, and Australia without associated disease outbreaks. Nor was there mention of how easily disease transmission from bats can be avoided—in most of the world by simply not handling or eating bats. Even more troubling is the fact that program producers were well aware of these omitted facts.

On May 7 and 8, production staff conducted nearly two hours of phone interviews with me and Teresa Nichta and received abundant documentation from us. We even offered outstanding video footage showing the popularity of bat-watching tourism in Austin, Texas and planned to schedule filming at various sites in Texas upon their request. They seemed quite excited about our help, promising to get back to us in a few days with final plans. Then, they simply disappeared. We can’t avoid wondering who nixed the production staff’s enthusiasm for sharing such a key demonstration of bats making safe and invaluable neighbors. I suspect that Anderson Cooper will be surprised if ever he learns of this.

The bottom line — Frightened humans seldom tolerate and often kill bats. Programs that promote fear, regardless of good intentions, threaten bats and their essential services as valued neighbors.  

Please remember, there is no credible science documenting that bats are responsible for the transmission of COVID-19, Ebola, SARS, or MERS, to humans. Anyone implying such transmission is speculating. Be vigilant in your media consumption and sharing! 

TAKE ACTION!

Our combined voices can make a difference. We invite you to politely share your opinion in your own words with the producers and editors. You may find our resources, Give Bats a Break and Good Intentions Can Still Leave a Bad Taste, additionally helpful in composing your personal reply and discussing these topics with others. Editors do take notice. Remember, your response can be very simple such as, “I don’t appreciate misleading speculation that perpetuates needless fear of bats.” Editors just need to know you like or dislike an article in order for you to have impact. It’s numbers that count. Bats need all of you! Tell a friend about bat values and how they can help.

Please lodge your polite, but firm complaint as soon as possible. Thank you for your vigilant support of bats, their conservation and MTBC.

The famous colony of approximately 1.5 million Brazilian free-tailed bats (Tadarida brasiliensis) living in crevices beneath the Congress Avenue Bridge in Austin, Texas has attracted millions of visitors to enjoy its spectacular emergences over the past 35 years. Small signs simply warn not to handle the bats, and despite countless close encounters no one has ever been harmed. The bats attract millions of tourist dollars each summer and consume tons of crop and yard pests each night.

Good Intentions Can Still Leave a Bad Taste

Disease

May 29, 2020

By Merlin Tuttle and Danielle Cordani

Wrong approaches in defense of bats can be even worse than not defending them at all. Articles, such as the one published in the May 15 issue of Scientific American, “Bats are Not Our Enemies,” are meant to defend bats, but can unwittingly perpetuate needless fear and intolerance. As experience has shown, despite good intentions, nothing can threaten bats more than fear.

The article’s subheading, “The viruses they carry spill over into humans mostly when we encroach on their territory or drag them into ours—and bats do great good as well” does nothing to quell fear. Readers should be wary of praising articles that include misleading statements about disease or ones that promote separation from bats as a solution.

Without putting disease risks in perspective, simply stating the value of bats cannot counteract the belief that bats are dangerous sources of deadly diseases, capable of threatening one’s family. People will always prioritize their own well-being rather than protect animals they fear. A study, currently in press, surveyed people on their willingness to support bat conservation. Support improved significantly only when fear was eliminated.

Millions of wrinkle-lipped free-tailed bats from Khao Chong Pran Cave in Thailand pass over thousands of tourists with whom local villagers do brisk business. Harvested guano sells for over $200,000 annually and the bats save local rice growers an estimated $300,000 per season. Despite decades of close contact, no disease outbreaks have occurred.

There is no documentation that Ebola, SARS, MERS, Hendra, or COVID-19 have ever been transmitted from bats to humans, though bats are often presented as the source of human infection. Such diseases are also mentioned as though they are widespread, without admitting that they (excluding COVID-19, of course) are rare or limited to specific geographic areas. For example, Americans have been warned that poop from a flying bat can give them Ebola, omitting mention that Ebola reservoirs are known only from Africa and haven’t been documented in bats even there!

Millions of tourists have safely observed spectacular bat emergences close-up in Austin, Texas for decades without harm. The bats consume up to 10 tons of insects nightly and attract millions of tourist dollars annually.

The study on which most media reports are based was clearly biased, claiming that bats harbor more viruses than other animals. It compared just 4 of the 26 orders of mammals and sampled nearly twice as many bats as all other mammals combined. Since new viruses can be found anywhere, a disproportionate search can be misleading. A far more thorough study recently concluded that bat species harbor no more viruses than other mammals or even birds, though it’s received very little media attention.

The recently promoted idea of restricting bats to protected areas is impractical and impossible to implement. As human populations expand, there is increasing need to share habitats. Even huge bat colonies can be safe neighbors, as demonstrated in cities like Austin, Texas. In fact, humans can benefit greatly. How can bats protect us from pests, pollinate crops, or generate tourist revenue if excluded from our farms and neighborhoods?

Limiting habitat destruction is critical to preserving biodiversity and ensuring the survival of many species. However, it’s imperative that we learn to live harmoniously with wildlife wherever possible. Bat survival increasingly demands that we not only protect their natural habitat but share ours as well.

For people who don’t attempt to handle or eat bats, the odds of contracting any disease from them are extremely remote. People have learned not to kick beehives or run into yards guarded by unfamiliar dogs; they can just as easily learn not to handle bats.

Bat Flash! Respond to Nipah Virus Warnings

Bat Flash, Disease

By Merlin Tuttle
12/19/19

A December 8 Reuters press release, titled “Health experts warn of emerging threat of Nipah virus,” reported on a two-day Nipah conference in Singapore; picked up by CNA Asia and making headlines across much of Asia. On December 13, CNA World further reported that some experts believe Nipah to be a pandemic threat.

 

Both articles report flying foxes to be the carriers of this “deadly disease,” failing to mention its rarity or ease of prevention and speculating it to be a high-risk source of disease outbreaks over broad areas despite an absence of  historic documentation. There was no mention of the vital importance of flying foxes as key pollinators / seed dispersers or the necessity and ease of learning to live safely with them. Such exaggerated warnings threaten bats everywhere, but none more than flying foxes that are already in alarming decline.

 

Claims that such rare viruses are poised to become the next pandemic are no more than long-shot guesses. Predicting the source of the next pandemic is extremely complicated, costly, and risks the reputations of scientists who claim such ability. Funding priorities should focus on prompt surveillance and control, not prediction.  (more…)

By Merlin Tuttle

 

Two grey-headed flying foxes, Pteropus poliocephalus, hang form a tree branch during a rain shower.

Doug Gimesy ranks among the very best when it comes to wildlife photographers. His numerous awards include winning the Wildscreen Panda Photo Story Award in 2018 and selection as the Australian Geographic Nature Photographer of the Year in 2019. But most importantly he is changing the way the world thinks about nature, having a heart for Australia’s much maligned flying foxes. He explains, “My hope is that the images and information I share will inspire people to stop, think, and treat the world a little more kindly.”

Doug is persuasively teaching the world about Australia’s flying foxes, from his story, “Night Gardeners” in the BBC Wildlife Magazine to “Urban battler” in Australian Geographic. View more of his flying fox photos on his site. (more…)

WNS: Can a Cure Be Effective?

Bat Flash, Disease, White-nose syndrome

7/12/2019
By Merin Tuttle

 

Amid media announcements that the fungus that causes white-nose syndrome in bats has spread to California, and growing public concern, The Wildlife Society announced the most recent attempt to find a cure. On July 9, an article titled “Bacteria treatment helps bats survive white-nose syndrome,” suggested progress toward a cure. However, there is no evidence that human intervention can slow the spread or cure the disease. As I’ve reported, the best available studies from the Northeast indicate that population recovery at key sites is exceeding expectations, and that a cure is unnecessary, impractical to implement, and risks unintended negative consequences.

Thank You For Your Voice – Editors are Listening and Bats are Benefiting

Bat Flash, Conservation, Disease, Members

By Merlin Tuttle
6/27/19

A reminder that our members DO make a difference! Leading news media outlets are changing tack, publishing more positive, and fewer negative, stories about bats as a direct result of MTBC members’ ongoing support and actions.

Your vigilance brings misleading articles to our attention. Your support enables us to carefully document and explain issues of concern. Your personal, diplomatic comments to editors influence their further actions. Media portrayal of bats cannot be ignored. It is key to broad public understanding and support, without which conservation progress could prove impossible.

The intermediate horseshoe bat (Rhinolophus affinis) ranges from northern India to southern China. It is one of the horseshoe bats speculated, but still unproven to have caused the SARS epidemic.

Since 2014, we’ve prepared and distributed 15 blog posts and 18 Bat Flashes providing counterpoint documentation in response to exaggerated, misleading, and often completely wrong speculation attempting to link bats to rare, but scary diseases. Widely distributed publications included “Give Bats a Break” in Issues in Science and Technology (subsequently translated into French and Chinese), “Fear of Bats and its Consequences” in the Journal of Bat Research and Conservation, and “Humans Shouldn’t Be So Scared of Bats” in Slate. Additionally, the science journal, Nature, published a co-authored response in its correspondence section, titled “Don’t misrepresent link between bats and SARS.” (more…)

Bat Flash! Scientific Credibility Under Siege—Sound Data Versus Premature Speculation

Bat Flash

By Merlin Tuttle
2/21/19

Just as we enter a period of exceptional need for reliable science to protect and restore a healthy planet, too many traditionally prestigious science journals and institutions are rewarding bad science. (1) (2) “Scientists are supposed to relentlessly probe the fabric of reality with the most rigorous and skeptical of methods.” (3) Yet traditionally credible journals like Nature and Science are increasingly publishing sensational speculation, particularly studies attempting to link bats to deadly diseases. (4)

Growing numbers are attempting to prove rather than test hypotheses, sometimes based on a sample of just one viral fragment from a single bat. (5) Kai Kupferschmidt’s article titled, “This bat species may be the source of the Ebola epidemic that killed more than 11,000 people in West Africa,” exemplifies the problem. It is based on a highly questionable sample from one bat, though it appeared in the online news site of the journal Science (January 24, 2019).

The common bent-winged bat lives in caves and cave-like locations from southern Europe to Japan and Southeast Asia to China, the Philippines and Solomon Islands, most of Africa and eastern Australia. It is insectivorous, often feeding on small beetles, and forms large colonies, some exceeding 100,000 individuals.

As is typical in such stories, it begins with a scary question that will grab readership and media attention. That Science title is followed by a emboldened quote stating that “This is an important new lead and it should be followed up extensively.”

Later quotes, less emphasized, admit that only a small viral fragment was found, and that it may have come from an infected insect eaten by the bat. In other words, this bat may have simply eaten an Ebola-carrying insect, completely changing the bat’s role from implied source to controller. Perhaps if virologists weren’t so focused on proving that Ebola comes from bats, they might have found the true source by now.

A growing number of leading virologists are warning that virus hunting, promoted by such articles, is a costly waste. The unsupportable public health promises being made are likely to demean the credibility of science. (6) Scientists need incentives for finding the right answer rather than for simply getting published. (1)

Kupferschmidt’s article ends with a warning that bats shouldn’t be killed. However, as already documented, people seldom tolerate and often kill animals they fear, especially bats. (7) (8)

The New York Times ran a similar account of the same story, authored by Denise Grady. It was titled “Deadly Ebola Virus Is Found in Liberian Bat, Researchers Say.” The author admits “It feels premature scientifically” but fails to admit that the small viral fragment may have come from an infected insect eaten by the bat, making the bat a potential aid in limiting the spread of Ebola. They too, belatedly and ineffectively, admonish not to kill bats.

Sensational and premature reports like these are clearly irresponsible and risk great harm to both scientific credibility and the environment. (more…)

A Big Step for Bats

Bat Flash, Conservation, Disease

Merlin Tuttle
1/22/19

Today’s issue of TheScientist contains another outstanding example of how MTBC is making a unique, but critical difference for bats. This article [by Merlin Tuttle] was originally submitted as an email to the editor. On January 13, I explained the harm done by biased portrayal of bats. The editor promptly requested permission to publish my communication as an op-ed. We encourage our members to share it broadly. Nothing can threaten bats more than the fear and intolerance created by misleading disease stories.

Rousette fruit bats are essential pollinators and seed dispersers. They form colonies of many thousands in caves and abandoned mines where they are extremely vulnerable to extermination. Tens of thousands were killed at a single site in Uganda by humans overreacting to fear of Marburg virus.

Speculation linking bats to scary diseases has become lucrative, both in generating research grants and media readership. As historically documented, it can have devastating impact in fostering intolerance and even massive bat eradication. It also threatens the credibility of scientists and publishers and diverts critical public health funding from far higher priorities.

Many authors and publishers of such counterproductive speculation are well intended, just misinformed. If kindly approached with sound documentation of the harm being done, they are appreciative and can be extremely helpful as we have repeatedly demonstrated.

Bat Flash! Washington Post Exaggerates Disease Risk from Bats

Bat Flash

Merlin Tuttle’s Response
1/8/19

Lena Sun’s article, “On a Bat’s Wing and a Prayer,” in the December 13, 2018 edition of The Washington Post, though well intended, contains misinformation that can threaten both conservation and public health. It leads with two false premises: bats are “some of the most dangerous animals in the world” and the rare Marburg virus is an important threat to world health. (1)

This basic discovery was covered by several news media, each with a slightly different slant. We responded to this one because it contained the worst misrepresentations. It was the only one seen that claimed bats to be “some of the most dangerous animals in the world” in addition to exaggerating the seriousness of its threat to world health.

Since its discovery in 1967, Marburg virus has caused a dozen outbreaks, killing fewer than 400 people. All the so-called “emerging diseases” speculated to be associated with bats worldwide, have killed fewer than 20,000 people in the past 40 years.

By comparison, HIV from chimpanzees has killed more than 39 million people, (2) yet these more popular animals consistently escape being labeled as dangerous.  Among other viral killers in Africa, the World Health Organization reports more than 70,000 children die annually from vaccine-preventable roto virus infections. (3) It also warns of geometric growth in obesity, that according to the National Institutes of Health causes 300,000 preventable deaths annually in the U.S. alone. (4) And by extremely conservative estimate, the U.S. Centers for Disease Control and Prevention reports more than 23,000 Americans die annually from antibiotic-resistant bacterial infections. (5)

So why are we focusing limited public health resources disproportionately on the rarest threats? And why are rare risks from bats often exaggerated? The answers are simple. Bats are little known, widely feared, easy to sample, and have few defenders. Also, new viruses can be found wherever we look. These combined facts make bats uniquely vulnerable to a seemingly perfect storm.  Speculation linking them to equally little known, but scary viruses has proven extremely lucrative in gaining unprecedentedly large grants and media readership, while diverting limited public health funds from far higher priorities. (6) (7)

Historically, bats have one of our planet’s finest track records of living safely with humans. Millions live in cities from America to Africa, Asia, and Australia, and have not caused even one of the world’s great pandemics. Diseases associated with bats are easily avoidable, mostly by simply not handling them. (7) Until more is known about Marburg, African caves where the virus may exist should be avoided.

For those visiting Africa, risks from mosquito-transmitted malaria or dog-transmitted rabies are orders of magnitude higher than those from any of the so-called “emerging,” but ancient, diseases speculated to be associated with bats. Our real fears should focus on preventing further loss of these already alarmingly declining, but ecologically and economically essential animals.(7)

Bat Flash! Response to Exaggerated Pandemic Threats from Nipah Virus

Bat Flash

Author Correspondence Update
12/26/18

12/19/18 Steven Bedard response

Dear Mr. Tuttle,

“Thank you so much for your concern, and for reading the bioGraphic story about Nipah virus. I really appreciate it. I assure you that I am a strong proponent of bats and the tremendously important ecological roles they play. I also think that bats are simply amazing creatures in their many forms and functions. (When you have time, please take a look at bioGraphic‘s other bat stories as evidence of that appreciation: Glimmers in the Dark, Battling Disease, Bat Ballet, and Agave Whisperers.)”

He went on to explain it is never his intention to vilify or advocate killing of bats and hopes he is being clear.

 

12/20/18 Merlin response

Dear Steven,

“I do not doubt your concern for bats or your good intentions. As I’ve commented, most of your article was just fine. My complaint lies in labeling bats to be the most dangerous disease-spreading mammals. Our background experiences are apparently strikingly different. Mine regarding the impact of public fear have been summarized recently. I’d be delighted to learn more about whatever experiences led you to your apparently differing concerns. However, I’d much prefer to simply share our perspectives over the phone.”

 

12/20/18 Steven Bedard response

Dear Merlin,

“Thank you for your reply. I look forward to the opportunity to speak with you. I first heard of your research when I was an undergrad studying zoology and ecology at Colorado State in the late 80’s, so it would be an honor to “meet” by phone.”

He further notes that he extensively interviewed disease experts and explains, “You will see in the article that I chose my words very carefully. I did not say that ‘bats are the most dangerous disease-spreading mammals.’ Humans hold that dubious distinction. What I wrote is that, ‘Among mammals, bats rank number one in terms of their role in spreading zoonotic diseases.’ That statement is most certainly true, according to my sources, as well as published research such as this Nature paper published in June 2017.

He also noted, “Some of your followers have expressed concern that if people in Bangladesh understand where the virus is coming from that they will begin to persecute bats.”

[Merlin’s thoughts—That is a serious misunderstanding. Scientists and conservationists have a responsibility to inform the public of disease sources, locations, and how to avoid them. We also must condemn sensational speculation and exaggeration, either of which can seriously harm both public health and bats.]

 

12/21/18 Merlin response

Dear Steven,

As per your suggestion, I’ve read your recent stories from bioGraphic and congratulate you on some very fine promotion of bat values. In fact, your “Glimmers in the Dark” article is the best I’ve seen on WNS. Given your clear concern for bats, I’m especially looking forward to speaking with you by phone when you return early in the New Year. When ready, simply suggest a time and phone number, and I’ll be happy to call.

Attached photo

We’ve likely had rather different experiences on the impact of exaggerated disease fears. Unlike you, I’ve had the misfortune of repeatedly seeing the results first hand.

During my early research in Tennessee, I met cave owners who burned many thousands of endangered gray bats by lighting kerosene in their roosts due to exaggerated rabies warnings. In Mexico, I took the attached photo of a few of the estimated 250,000 skeletons of insect-eating bats we found on reopening a roost where a fearful owner had sealed the bats inside. And, while photographing bats for my 2014 National Geographic article, I found a major bat cave recently sealed (with the bats inside) due to disease fears in a Cuban national park. In my experience, people seldom tolerate and often kill animals they fear. In fact, the free-tailed bat colony speculated to have been the source of the 2014 Ebola outbreak was burned in its roost.

Seeing how well intended you are, I hope you will read my 2017 report on fear-motivated bat killing and its impact on conservation. I am quite familiar with the Nature paper reporting that bats harbor a significantly higher proportion of zoonotic viruses than any other mammal group and look forward to discussing it with you.

[Note that Merlin has rebutted the aforementioned Nature article, read his response HERE.]
