Fort Collins rabbits display hornlike growths caused by Shope papillomavirus, a common infection in rabbits that does not threaten humans.

Colorado rabbits show hornlike growths linked to a common virus

A group of rabbits in Fort Collins has been spotted with hornlike growths on their faces. Scientists identify Shope papillomavirus as the cause. The virus is common among rabbits and does not spread to people or pets.

The growths resemble horns or warts and may look alarming, especially in photos circulating online. They rarely harm the animal unless the growths interfere with eating or sight. Rabbits typically mount an immune response, and the growths can disappear as the virus runs its course. The pattern is more visible in summer when flea and tick activity rises and helps spread the virus among rabbits.

This episode shows how online chatter can turn a simple wildlife finding into public spectacle. The rush to label the rabbits with dramatic terms often outpaces the science, reflecting a gap between folklore and biology. It also reveals why clear science communication matters for local residents and the wider audience.

The story underscores the need for wildlife and public health officials to provide calm, precise explanations. By explaining the virus, its limits, and the lack of risk to humans, authorities can curb sensationalism while keeping communities curious about nature. The tale also echoes a long arc in science where curiosity about odd animal traits furthers medical knowledge and public understanding.
