“Touching a frog or toad gives you warts”

It's a common childhood warning: "Don't touch that toad, or you'll get warts!" This old wives' tale has been passed down through generations, often with the best intentions, to keep children from handling amphibians. The enduring nature of this belief likely stems from a visual association rather than any actual biological threat, as the bumpy skin of some toads can bear a superficial resemblance to warts found on humans.

However, the scientific truth is clear: warts are caused exclusively by the human papillomavirus (HPV). This virus is species-specific, meaning it can only infect humans and cannot be transmitted from amphibians to people. The bumpy texture on a toad's skin, which might look like warts to the untrained eye, is actually a collection of glands. These glands are a natural part of the toad's anatomy, often used for defense by secreting mild toxins, but they pose no risk of wart transmission.

The myth's staying power is understandable. The visual similarity between the rough skin of a toad and a human wart is striking enough to create a memorable, albeit incorrect, link in people's minds. Coupled with the natural human tendency to seek simple explanations for observable phenomena, the idea that touching a bumpy creature could lead to bumpy skin seemed logical. Rest assured, you can admire amphibians without fear of developing warts from their touch; the human papillomavirus is the sole culprit.
