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.

Bat Flash! Respond to Nipah Virus Warnings

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…)

WNS: Can a Cure Be Effective?

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

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! New York Times Misrepresents Rabies Facts

 

Merlin Tuttle’s Response
6/25/19

For at least the second time this year, The New York Times has published facts involving bats and disease in a misleading manner. At a time when bats are in special need of conservation, scary speculation is extremely counterproductive. In February of this year, we issued a Bat Flash, and members contacted Times authors and editors to caution them about the negative impact of premature disease speculation.

Now bats need you to speak up again. On June 14, 2019, I responded with the following communication to The New York Times Editor:

I read with interest the recent article, “Bats, Not Dogs, Are the Most Common Source of Rabies,” by James Gorman. As a biologist who has studied and photographed hundreds of species of bats worldwide, I have personally documented instances in which thousands, even millions of bats have been burned in their caves due to misleading warnings that incite needless fear. In fact, fear of bats is often the single greatest impediment to their conservation.

I’m deeply concerned because bats are essential to whole economies and ecosystems upon which we, ourselves, depend. Their loss threatens our future, far more than any possible disease transmission. Education regarding the benefits of conserving bats is urgently needed. (more…)

Bat Flash! Step Two to Help Cairns’ Flying Foxes

(Scroll down for action links!)

We want to thank each of you who contacted Mayor Bob Manning in response to our Bat Flash in March on behalf of an urgent threat to Australia’s now critically endangered spectacled flying foxes. We appear to be having important impact, as just reported by Sera Steves, Secretary, Bats and Trees Society of Cairns.

A spectacled flying fox (Pteropus conspicillatus) pollinating a black bean tree (Castinoperum australis), a prized timber tree in Australia.

“The mayor and council are visibly and vocally struck by the amount of email responses they’ve gotten, good work! However, they continue to hide behind the false idea that a dispersal is for the good of the bats. The welfare argument needs to be shot out of the air and the focus needs to be on tourism potential. The feedback from tourists proved valuable in response to an article in the Cairns post about dispersing the bats with pool noodles, pyrotechnics, gas guns, stock whips and air horns.”

Another step is still needed…

Bat Flash! Australian Flying Foxes Urgently Need Immediate Help

Cairns Mayor, Bob Manning, wants to force flying fox survivors to leave his city. This is planned for the near future, making it an urgent issue. Recent heat stress and starvation have killed 1/3 of the flying foxes in his city. Survivors remain in grave danger. One simple, impactful thing we can do is email this Australian mayor, b.manning@cairns.qld.gov.au, politely asking him to stop all planned efforts to chase endangered flying foxes from their traditional homes in Cairns. They’re already desperate, and many more may die if forced to move.

We must learn to live in harmony with nature! Please visit the link in our bio for more about climate change and flying foxes. Also, follow @sera_loves_crocs on Instagram as well as BATSOC (Bats and Trees Society of Cairns) @batsandtreessocietyofcairns, on Instagram and Facebook for further updates and details.

 

 

TAKE ACTION!

Our combined voices can make a difference. Send an email to Mayor Bob Manning to politely make him aware of international concern for Australia’s flying foxes. Cairns is a major tourist destination where potential visitors have extraordinary influence. He just needs to know you like flying foxes and hope to see them protected as some of his country’s most valuable and fascinating wildlife. It’s numbers that count. Australia’s flying foxes need all of you!

Bat Flash! Response to Exaggerated Pandemic Threats from Nipah Virus

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 DarkBattling DiseaseBat 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.]

Bat Flash! Action Needed for Durian Pollinators at Risk

The durian is considered the king of fruits throughout Southeast Asia, but it can’t be produced, even in orchards, without bats to pollinate its night-blooming flowers. This important crop could be lost without better appreciation of the key contributions of bats and their habitat needs.

It’s time to give these bats a voice. Rimba’s media statement: Deforestation for Durian Plantations Poses Serious Long-term Risks to Industry’s Productivity and Profitability calls others to action on behalf of durian pollinators. The Star recently published an article, Durian farmers pay the price in the end, highlighting Rimba’s work, reaching more than 7 million unique visitors.

Malay Mail published another supporting article, Weighing in on bats and durians, which boasts over 3 million unique visitors not including the printed version.

The Rimba news release emphasizes the serious impact of deforestation-driven durian expansion to all relevant parties. They call on the Ministry of Agriculture and Agro-based Industry, the Department of Agriculture, the wider durian industry, and individual durian farmers to “think long-term and pursue good agricultural practices for growing durian that is sustainable, contributes to healthy ecosystems, and provides a future for the Malaysian durian industry and Malaysian durian lovers.”

The overall objective of their plan is to promote coordinated action worldwide to safeguard wild and managed pollinators and promote the sustainable use of pollination services, which are vital to both ecosystems and agriculture. We are delighted to see Rimba’s efforts on behalf of bats and the economies they support getting this well deserved attention. Let’s use our voices to amplify the message! (more…)

Response to Sensational Bat Rabies Stories

Every year around this time there is a spike in needlessly sensational rabies stories featuring exaggerations of truth.  We always encourage others to respond politely to editors, authors, decision makers and media personnel when they see these. Editors’ jobs depend on readership and they do aim to please. They just need to know you like or dislike an article. Responses can be very simple such as, “I don’t appreciate  sensational  headlines or speculation that creates needless fear of bats.”

We work hard to be a source for your personal ambassadorship of bats and wish we could respond to every article, however our resources are limited. We cannot do it alone. We hope that this post will supplement your future responses when you encounter false or exaggerated bat publicity.

 

Response to Beth Skwarecki’s story “If a Bat Was in your Bedroom, You Probably Need a Rabies Shot
By Merlin Tuttle
9/1/18

Unfortunately, this well intended story is a sensational exaggeration of truth. It is correct to say that most human rabies in America comes from bats. However, put in context, it’s just 1-2 cases per year, making it one of the rarest causes of death. By comparison, just by riding one mile in a motorized vehicle, an American exceeds his/her annual risk of rabies from any source.

Because even sick bats almost never bite, except in self-defense if handled, the risk of contracting any disease from one is exceedingly low for anyone who simply leaves them alone. In Austin, Texas, thousands of people gather nightly to observe the spectacular emergences of 1.5 million bats close-up. And in decades of this exceptionally close association, no one has been attacked or contracted a disease.

Post-exposure rabies vaccinations in the United States are outrageously overpriced, currently costing from $10,000 to $22,000 per person treated. With huge profits at stake, and our CDC heavily influenced by drug companies, promotion of exaggerated fear is not surprising. Unprovoked bites are exceedingly rare, so much so that I have yet to experience one despite close association with millions of bats worldwide for more nearly 60 years.

Human rabies cases are often diagnosed post-mortem or after the patient is incoherent. Even in cases in which parents or friends report bites, the U.S. CDC reports “no bite history” unless the patient is able to confirm. Consequently, human cases, regardless of animal origin (i.e. bat, dog, skunk or raccoon) often get reported as having no bite history. Huge misrepresentation occurs when such reports are used to disproportionately frighten people of bats.

Since 1996 the CDC Advisory Committee on Immunization Practices has advised consideration of post-exposure prophylaxis for “persons potentially exposed to bats even where a history of physical contact cannot be elicited,” unless prompt diagnosis excluded rabies. Based on its independent analysis Canada’s National Advisory Committee on Immunization, opted not to follow CDC’s recommended bat policy.  They do not advise vaccination unless there has been direct contact. For detailed documentation, see Rabies in Perspective.

Millions of tourists have watched free-tailed bat emergences from the Congress Avenue Bridge in Austin, Texas over the past 35 years without anyone ever having been harmed.
