Hold onto your face masks, folks—science just flipped the script on virus transmission! A groundbreaking study published in Nature Ecology & Evolution found that humans give twice as many viruses to animals as we catch from them. Let that sink in: we’re the superspreaders.
Researchers analyzed nearly 12 million virus genomes and discovered 3,000 instances of cross-species jumps. Of the human-related cases, 64% were human-to-animal transmissions (aka anthroponosis), affecting pets, livestock, and wildlife like raccoons and marmosets. Only 36% went the other way (zoonosis). Wild animals bore the brunt, highlighting humanity’s environmental footprint.
“This shows our enormous impact on nature,” said lead author Cedric Tan of University College London. Viruses spread through contact, bites, or even just sharing ecosystems. But here’s the kicker: most cross-species jumps fizzle out. Only a few—like COVID-19 (likely from bats) or bird flu—spark pandemics.
And yes, even minks got COVID from us during the pandemic. Talk about a plot twist! The takeaway? As we reshape habitats, we’re swapping germs with wildlife more than ever. Time to rethink our role in the viral web.
