Bat Flash! Response to The Conversation

12/28/2021

The series Curious Kids, hosted by The Conversation, is designed to provide expert answers to questions asked by children from around the world. The December 16 edition, “Curious Kids: why do bats pass diseases to humans”  is filled with media-driven disinformation that harms both the credibility of science and conservation efforts for bats, while doing nothing to dispel unfounded fear.

 

The question, “why do bats pass deadly diseases like Ebola to humans,” is proposed under the assumption that bats carry more diseases than other animals. Early in the article, the author states “Bats are both more likely than other animals to have a wide variety of diseases like Ebola, rabies, and coronaviruses and more likely to pass them on to us.”

 

This assumption is based on one of the most cited studies that wrongly accuses bats of hosting more viruses than other mammals, wherein the authors surveyed twice as many bats as all other mammals combined. Because new viruses can be found wherever we look, it is not surprising to find more in the animals that are predominately searched. More inclusive research concluded that bats do not harbor more viruses than other animals, though it has been mostly ignored by those seeking media attention.

In fact, despite relentless searching and endless speculation, SARS-CoV-2, SARS, MERS, and Ebola viruses have not been found in a bat, nor is there documentation of transmission from a bat to a human. The record of unsubstantiated speculation attributing Ebola to bats is long, despite the earliest outbreaks being traced to the consumption of chimpanzees and gorillas, not bats. Recent research indicates that Ebola has been endemic in humans over long periods of time, possibly across generations, and that such evidence has been repeatedly ignored in a rush to blame bats.

 

In truth, bats have one of our planet’s finest records of living safely with humans. In Austin, Texas, the spectacular evening emergence of 1.5 million bats has become a world-famous tourist attraction, and no one has been harmed. Dire warnings of disease from bats come from those who profit from fear. For anyone who simply doesn’t attempt to handle bats, the odds of contracting a disease from one are extremely remote!

 

Children need to learn to appreciate, value, and live safely with nature, not fear it.

Bat Flash! Where Did COVID-19 Really Come From?

01/28/21

By Merlin Tuttle

USA Today’s January 17 story, Where did Covid-19 come from? leads with the following statement “The coronavirus that conquered the world came from a thumb-sized bat tucked inside a remote Chinese cave. Of this much, scientists are convinced.”

Deep in the story, they quote virologist John Connor at Boston University, saying ‘It looks like it’s a bat-derived virus, and there’s a big question mark after that.’ Fellow virologist, Charles Chiu, an expert in viral genomics at the University of California—San Francisco, is additionally quoted as saying ‘It may also have emerged from any setting in which people come into contact with animals, including farms, pets or zoos.’

Clearly, all scientists are not convinced that this virus came from bats, not even those interviewed for this story. The disproportionate focus on bats as the source of the COVID-19 pandemic is based on poorly supported speculation that harms conservation efforts worldwide.

Intermediate Horseshoe Bat (Rhinolophus affinis)

One of the most cited studies accuses bats of hosting more viruses than other mammals. Yet, the authors of this study surveyed twice as many bats as all other mammals combined. More inclusive research suggests that bats do not harbor more viruses than other animals.

New viruses can be found wherever we look, so it is not surprising to find more in the animals that are predominately searched. The claim that the SARS-CoV-2 virus, the source of the COVID-19 pandemic, shares 96% of its genetic material with a coronavirus found in a horseshoe bat is meaningless. We ourselves are 96% genetically similar to chimpanzees which we easily recognize as non-human.

Current biases threaten the survival of bats that have undisputed value and are already in alarming decline. They also harm science credibility and misdirect the search for zoonotic reservoirs by focusing disproportionately on bats. Despite relentless searching and endless speculation, there is no documentation that SARS-CoV-2, SARS, MERS, or Ebola viruses have been found in, or transmitted from a bat to a human.

As noted by Yong-Zhen Zhang and Edward Holmes, it is critical that coronavirus surveillance should include animals other than bats. Blaming bats based on one-sided searches is premature and misleading.
