In Fort Collins, Colorado, residents and hikers have been stunned by the sight of rabbits with horn-like or tentacle-like growths protruding from their faces. While their appearance may seem like something out of a horror movie, the reality is more scientific than frightening: these animals are affected by the Shope papillomavirus, an infection that causes keratinous growths that can reach several centimeters in length.
Far from being a new threat, this virus is relatively common in rabbits and poses no danger to humans or pets. However, their unusual appearance has earned them nicknames such as “Frankenstein rabbits” or “zombies,” with photos and comments spreading quickly on social media.
The virus is mainly transmitted through fleas and ticks, especially during warmer months. Although the growths can make it difficult for the animal to see or eat, in most cases their immune system manages to overcome the infection on its own.
Can they infect other animals or people?
No. The virus only affects rabbits and does not spread to other species. Still, authorities advise avoiding physical contact with infected animals and leaving them in their natural environment, so the healing process can take its course.
