“You can get warts from touching a toad.”

The persistent belief that touching a toad will give you warts is a classic example of how visual similarities can lead to widespread misconceptions. The bumpy skin of many toad species, which are actually glands, bears a superficial resemblance to human warts. This visual connection, coupled with a lack of scientific understanding in earlier times, likely fueled the folk tale, warning children away from handling these amphibians.

However, the scientific truth is that human 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 other animals, including toads. The bumps on a toad's skin serve various functions, such as camouflage or housing glands that can secrete mild toxins for defense, but they do not harbor the HPV virus or any other pathogen capable of causing warts in humans.

Despite modern scientific knowledge, the myth endures, passed down through generations. This is often because the initial visual connection is so strong and the story is easy to remember and repeat. While handling toads is generally harmless in terms of wart transmission, it is always wise to wash your hands after touching any wild animal.
