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.
This story further repeats the poorly founded claim that bat species harbor more coronaviruses than any other group of mammals, assuming without validation, that this makes them uniquely dangerous. The claim is based on a study of fewer than half of the world’s bat families, presumably those that are the largest, most widespread and diverse, the ones most likely to harbor the highest viral diversity. These were then inappropriately assumed to be representative of the remainder that were less diverse and widely distributed as well as less colonial.
Sampled species were not reported, nor was their roosting or feeding behavior. Since the large majority of viral fragments detected came from feces, many could have come from arthropod carriers eaten by bats. This could falsely lead to the conclusion that bat vector controllers instead serve as reservoirs. Despite such biases, these results are now reported as documented facts.
One can only wonder how so many biases can be so consistently overlooked, despite historical evidence that huge bat colonies, even in cities, make safe and highly beneficial neighbors. Unfortunately, scaring us about bats has proven lucrative in gaining large research grants for projects of questionable value. It also seriously threatens some of our planet’s most endangered and valuable animals. Finally, this story provides no new discoveries of how bats might help prevent pandemics, as its title implies. Bats are indeed, largely immune to major human threats, such as cancer and arthritis, and when research objectives are revised, may provide a goldmine of useful discovery.
My comments can be seen at the end of THE CONVERSATION article. We encourage you to do the same in your own words by following the directions below. Also, we encourage you to freely contact the editors and authors of any similarly negative articles you find.
Remember, your response can be very simple such as, “I don’t appreciate attempts to create 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!
