Bats are essential to healthy ecosystems and shouldn’t be killed, but this message is eroded when accompanied by disclaimers urging us to stay away from bats combined with images of researchers in protective uniforms working with bats. Continue reading

Merlin’s op-ed, “A Viral Witch Hunt,” published in Issues in Science and Technology on March 27, 2020 illustrates how misguided focus on bats as speculated sources of scary diseases threatens an invaluable resource and leads to misdirection of public health resources. Continue reading
Bats and Disease Facts
- Bats harbor no more viruses than other animals1.
- Claims of disease from bats are often based on poorly supported speculation2,3.
- Reports of 96% genomic similarity between viruses are misleading without proper perspective. We are at least that related to chimpanzees but remain vastly different4.
- Promises to predict future pandemics are misdirecting billions of dollars to virus hunting that is biased against bats and could be better invested in other public health priorities5,6,7.
- Bats have an undeniable history of living with humans without causing disease outbreaks8.
- There is a long history of disease exaggerations harming bat conservation9.
- Fear of bats leads to intolerance and killing9,10 .
- Asking people to conserve bats because they are beneficial, while failing to counter exaggerated fear, is unlikely to improve conservation success10.
- There are no confirmed cases of SARS-CoV-2 transmission from bats to humans11.
- SARS, MERS, SARS-CoV-2, and Ebola have not been isolated in, nor proven to be transmitted from a bat to a human, despite frequent speculation and intense searching12,13,14,15,16.
