Colorado Rabbits Displaying 'Horns' Due to Shope Papillomavirus

What's Happening?

In Fort Collins, Colorado, a group of cottontail rabbits has been observed with wart-like growths resembling horns on their faces. These growths are caused by Shope papillomavirus, a virus that is relatively common among rabbits. The virus, named after Dr. Richard E Shope who discovered it in the 1930s, has inspired folklore such as the jackalope myth. The growths, while visually striking, are mostly harmless unless they interfere with the rabbits' ability to eat or see. The virus spreads primarily through fleas and ticks, and is most active during the summer months. Colorado Parks and Wildlife has received numerous calls from residents concerned about the rabbits, but officials assure that the virus does not affect humans or pets.

Why It's Important?

The presence of Shope papillomavirus in rabbits highlights the intersection of wildlife health and public interest. While the virus itself poses no threat to humans, the unusual appearance of the rabbits has sparked curiosity and concern among local residents. This situation underscores the importance of understanding wildlife diseases and their impact on ecosystems. Additionally, the virus has historical significance in scientific research, contributing to the understanding of the relationship between viruses and cancer. The attention drawn by these rabbits may lead to increased awareness and interest in wildlife health and conservation efforts.
