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.
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…)
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…)
A Terrifying Time for Bats By Merlin Tuttle
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.
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
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
Once again, bats are plagued with a rash of sensational bat-attack and bat-disease stories, promoted by clever, but unscrupulous persons who know better. The motivation remains the same—greedy competition for public health funding. As noted by Mexico’s leading bat biologist and conservationist, Dr. Rodrigo Medellin, “unsupported statements and partial truths have been cleverly interwoven to present a picture that bats are the most dangerous, filthy, pathogen-harboring organisms on earth.” So-called virus hunters are linking already feared bats with deadly, but rare diseases, misleading governments to invest billions of dollars in projects of questionable value in saving human lives (USCDC 2015).
The current article in The Independent, is typical, first the scary headline that leaves a lasting impression on readers, despite later qualifiers, most of which go unread. The subtitle says, “Diseases in bats have been around for a long time and historically have not been a problem. Now, there is cause for concern.”
Those promoting this international campaign of fear are clever wordsmithers. They know just enough about bats and diseases to almost imperceptibly distort the truth, scaring people about potential, but unlikely events. Extremely low risks are made to seem imminent and possibly disastrous. And since neither bats nor viruses are well understood, they are ideal victims for such manipulation.
Bats and Viruses, edited by Lin-Fa Wang and Christopher Cowled, provides the first summary of current knowledge on how bats and viruses interact. It is an invaluable resource for all who are concerned about bats, whether from a public health or a conservation perspective. Given the rate of viral discovery it is commendably up-to-date.
Viral discoveries, distribution, potential for zoonoses, best practices, research biases and areas in need of further investigation are thoroughly covered.
Bats appear to serve as reservoir hosts for several of the world’s deadliest diseases. However, as noted, transmission to humans or their livestock is rare, and in most cases can be easily avoided. Advice not to eat bushmeat, handle unfamiliar animals, mix unquarantined wildlife in markets or plant fruit trees where flying foxes can be lured into close proximity to livestock is appreciated.
Numerous biases and possible misinterpretations are explained. Viral reservoirs cannot be confirmed based on mere presence of viruses or antibodies, and those found in bat guts or feces may come from insects or other foods. Also arthropods such as mosquitoes can simultaneously infect more than one species with identical zoonotic viruses, giving a false impression of transmission between incidental hosts.
