Bat Flash! CNN Misses the Mark

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!

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

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! COVID-19 Coronavirus Leads to More Premature Scapegoating of Bats

By Merlin Tuttle
Updated 03/26/20

The source of human exposure to the COVID-19 virus, or as it was first called, Wuhan virus, according to the March 12th edition of The Conversation, has yet to be identified. However, in a rush to judgment, far too many public health officials and media outlets are focusing almost entirely on bats. This has been seen in multiple news sources, from CNN to Vice. Such speculation can be counterproductive, especially when acted on as fact.

Bats, despite their essential ecological and economic roles, rank among our planet’s most rapidly declining and endangered animals1. They have few defenders and are often mistakenly viewed as dangerous. People who fear bats are less tolerant and frequently kill them 2.

Fear is needlessly created when virologists emphasize potentially distant evolutionary relationships that shed little light on where and how a virus is actually transmitted to humans. Bats are currently believed to harbor more kinds of viruses than other mammals. But even if true, there is no credible documentation of higher risk of transmission3. Most viruses are innocuous or even beneficial 3,4.

Bats, like any living organism, are capable of harboring scary viruses, yet transmission is rare, typically only to humans who carelessly handle a bat that bites in self-defense, followed by failure to seek medical attention. Nipa virus, in India and Bangladesh, is acquired by drinking unpasteurized palm juice, eating unwashed fruit, or associating with sick pigs5.

For more than a decade, virologists have used increasingly sophisticated technology to disproportionately search for new viruses in colonial bats6. New viruses can be found by looking no farther than our own human bodies, and they’re all related at some level4! We’re 96 percent genetically identical to chimpanzees7.

Scientists at Singapore’s Bioinformatics Institute examined a key surface protein on the COVID-19 virus and found it just 79 percent genetically similar to SARS, noting that these viruses “are like comparing a dog and a cat.” 8 This flies in the face of widespread claims of similarity.

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

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! Smithsonian Promotes Misleading Virus Hunter Claims

By Merlin Tuttle
8/3/18

 

The July 11, 2018 edition of Smithsonian.com contains another highly misleading story on virus hunters protecting us from pandemics. The story by Katherine J. Wu is titled, “A Never-Before-Seen-Virus Has Been Detected in Myanmar’s Bats.” Wu claims that to prevent the next Pandemic, we need to pinpoint it at the source. She then reports that “researchers in Myanmar have hit pay dirt with a never-before-seen virus that infects wrinkle-lipped bats—a virus in the same family as the ones that cause SARS and MERS.”

After further extolling the virtues of virus hunting, she quotes Chelsea Wood, reportedly a conservation ecologist, as saying that, “Tropical rainforests [in particular] are just cesspools of viral diversity—the highest viral diversity on the planet.” The headline and rhetoric in this article sound more like grocery store tabloid writing than something one would expect from America’s leading institution of science.

This story is a complete contradiction of a paper by epidemiologists, Edward Holmes, Andrew Rambaut, and Kristian Andersen, titled “Pandemics: spend on surveillance, not prediction” which appeared in the Journal Nature on June 7, 2018. [1] Referring to virus hunting, they conclude that “given the rarity of outbreaks and the complexity of host-pathogen interactions, it is arrogant to imagine that we could use such surveys to predict and mitigate the emergence of disease.” They emphasize that broad surveys of animal viruses have little practical value when it comes to disease prevention. They conclude that such approaches are an extremely costly waste of limited public health funds and warn that “Trust is undermined when scientists make overblown promises.” (more…)

Scientists Unite in Protest of Unfounded SARS Claims

1/22/18
By Merlin Tuttle

The intermediate horseshoe bat (Rhinolophus affinis) ranges from northern India to southern China. Horseshoe Bats are so named due to their horseshoe-shaped nose-leaves. This is one of the species prematurely speculated to be the source for SARS.

Good science tests but does not attempt to “prove” hypotheses. Numerous attempts have been made to demonstrate a link between the origin of SARS and bats, and literally thousands of publications have reported it as documented fact.  The December 1 issue of Nature, included yet another example, this one titled “Bat cave solves mystery of deadly SARS virus—and suggests new outbreak could occur.” The article reports, “After a detective hunt across China, researchers chasing the origin of the deadly SARS virus have finally found their smoking gun.”

The January 16 issue of Nature, carries a rebuttal titled, “Don’t misrepresent link between bats and SARS.” Authors point out that the “smoking gun” metaphor is sensationalist and unjustified, potentially leading to culling and bat roost destruction.

Bat Flash! Respond to Misleading Attempt to Encourage Fear of Bats 12/1/17

By Merlin Tuttle
12/1/17

The November 23, 2017 issue of THE CONVERSATION lures readers with an important sounding, bat-friendly title, “Can bats help humans survive the next pandemic?” However, two-thirds of the article is devoted to promoting fear instead of progress and is based on questionable sources. This is particularly disturbing given the publication’s stated objective—“Fight for Truth in Journalism.”

This story is a simple repeat of close to a decade of often exaggerated speculation attempting to link viruses found in bats to transmission of scary but relatively rare ones like SARS and MERS to humans. Documented transmission of any disease from bats to humans remains exceedingly rare. And no one has successfully shown transmission of SARS or MERS from bats to other mammals. Dromedary camels are now well known to have been the source of MERS in humans for decades, likely longer.

A Terrifying Time for Bats

A Terrifying Time for Bats
By Merlin Tuttle
7/2/17

The past month has seen a virtual explosion of premature speculation presented as though it were now proven fact, much of it traceable to a single article titled, “Bats are global reservoir for deadly coronaviruses,” that appeared in the June 14, 2017 issue of Nature. We’ve already issued a Bat Flash alert responding to this article, and to predecessors, all apparently part of a single cleverly planned campaign.

An adult male Straw-colored fruit bat (Eidolon helvum) from Kenya. This is the species first blamed for the “index case” of Ebola in the 2014 outbreak in West Africa. The species was soon exonerated. In fact, it is so resistant to Ebola that it is an unlikely source. Recent studies suggest a source other than bats.

Sensational speculation has become widely cited as fact1, with spin-off damage that will be exceedingly difficult to reverse. All who truly care about bats have cause to be deeply concerned.

Due to scary speculation attempting to link the SARS outbreak of 2002 to bats, bats have recently become central in the search for viruses2.  Thus, rapid advances in viral detection alone may have caused major bias. Also, the number of viruses found in bats is not necessarily indicative of risk.2 Many viruses are innocuous or even beneficial,3 including some that are closely related to deadly ones.4 Finally, the paper in question is based on models, and models are notorious for mistaken conclusions, regardless of the amount of data analyzed.5

A far more meaningful analysis should have considered the historic rarity of viral spillover from bats to humans. Many media stories now claim bats to be the primary source of so-called “emerging infectious diseases” like Ebola, though most of these speculations remain unproven.6- 7

Thai women collecting guano in Rakang Cave. These women spend countless thousands of hours sweeping up the guano and bagging it while being pooped on by hundreds of thousands of fruit- and insect-eating bats high overhead and report no ill effects.

Proponents of such speculation still cannot explain why hundreds of bat biologists, millions of people who eat bats, and the millions more who share cities with huge bat colonies are no less healthy than others. They can’t explain why bats artificially infected with Ebola haven’t become contagious or why virologists haven’t even been able to find live virus in the thousands of bats examined. Certainly, like all other mammals, bats must be capable of harboring at least a few dangerous viruses. Nevertheless, bats still have one of our planet’s finest records of living safely with humans.1

Bat Flash! Nature Sensationalizes Bat Coronaviruses

By Merlin Tuttle
6/13/17

The June 12, 2017 story by Amy Maxmen, titled “Bats are global reservoir for deadly coronaviruses,” published in Nature, continues the needlessly sensational presentation of bats as exceptionally dangerous animals. By simple insertion of the words “global” and “deadly” in the title, it implies bats worldwide to be a serious menace to human health.

The article begins by stating that “Bats are the major animal reservoir for coronaviruses worldwide….” In the reported study, nearly twice as many bats as rodents, shrews, and primates combined were examined, not surprising. The emphasis on easily captured bats, likely centered on colonial species, is an approach that appears to have become the norm. And it’s impossible to know the extent of resulting bias.

A Chinese horseshoe bat (Rhinolophus sinicus) from Hong Kong. It has been suggested that a coronavirus found in this species is the direct ancestor of the virus that causes SARS. Nevertheless, despite seemingly endless speculation, no experiment has ever shown these, or any other bats, to be capable of transmitting a coronavirus to primates or other animals.

BAT FLASH! Sensational NPR Story Threatens Bats

Sensational National Public Radio Story Threatens Bats
By Merlin Tuttle
2/14/17

 

Unfortunately, the normally objective and reliable NPR, in its broadcast interview titled, Why Killer Viruses Are On The Rise, has joined in spreading irresponsibly sensational fear of bats. The interview with a “virus hunter” is set in a Bornean rainforest. In the preamble, the announcer notes that, “It’s where deadly viruses hide out, waiting their chance to leap into a person and then spread around the world.”

 

At a time when bats and rainforests are both in alarming decline, and in desperate need of protection, the program goes on to portray them in the scariest of terms. The reporter notes that rainforests “have lots of crazy animals” that “have lots of crazy viruses” and explains that what the virus hunter “really wants is to catch a bat.”

When the first bat is caught it is described as cute, but the reporter quickly points out that, “bats are arguably one of the most dangerous animals in the world. They triggered the Ebola outbreak in West Africa, the pandemic of killer pneumonia back in 2003, that was called SARS, and they’re behind one of the viruses scientists think could cause the next big one, Nipah.” This is unproven speculation reported as fact. But it gets even worse.
