The source of human exposure to Wuhan virus, according to the January 29th edition of The New York Times, has yet to be identified. However, in a rush to judgement, 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 Wuhan virus and found it just 76 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.
