The Fascination with Fort Collins' Demon Rabbits: Understanding the Papillomavirus

In recent weeks, a photo of a rabbit sporting horn-like growths has taken the internet by storm, captivating audiences worldwide and igniting a flurry of speculation. Dubbed “zombie” or “demon” rabbits, these creatures from Fort Collins, Colorado, have sparked both intrigue and concern. However, experts have clarified that these unusual appearances are the result of a harmless, naturally occurring virus.

The viral image, first reported by 9NEWS, showcases a rabbit with protruding facial growths that many found alarming. As the photo circulated across social media platforms, questions arose regarding its authenticity, with some speculating whether it was an AI-generated image. Yet, according to Kara Van Hoose, a spokesperson for Colorado Parks and Wildlife (CPW), the phenomenon is nothing out of the ordinary.

“This is a normal virus that happens every summer,” Van Hoose explained. The growths are attributed to a strain of the papillomavirus, which causes wart-like formations, particularly around the face of the rabbits. The virus is transmitted through vectors such as ticks, fleas, and mosquitoes, and can also spread directly from one rabbit to another, as noted by Dr. A. Alonso Aguirre, dean of Colorado State University’s Warner College of Natural Resources.

While the sight of these rabbits may be unsettling, the virus poses no danger to humans or common pets like dogs and cats. However, CPW advises pet owners to supervise their rabbits when outdoors to prevent any potential exposure. “These are mostly benign,” Van Hoose reassured. “We would become concerned if they were growing in sensitive areas of the rabbit’s face, like the eyes or mouth.”

The phenomenon has not only raised eyebrows locally but has also drawn attention from around the globe. Van Hoose shared that inquiries have come from as far away as the United Kingdom and India, as people seek to understand the curious case of the rabbits. “I think we’re seeing a lot of people scratch their heads [and asking], ‘What’s going on with wildlife in Colorado?’” she remarked.

Interestingly, the cottontail rabbit papillomavirus is part of a larger family of viruses that affect various species, including deer, cattle, horses, and even humans. Dr. Aguirre highlighted the significance of this virus in scientific research, stating that it has been instrumental in studying human papillomavirus (HPV). “The genome of this virus was sequenced back in 1984 and it’s been used as the first model to study human papillomavirus type 1,” he explained. This research has contributed to the development of several vaccines for HPV in humans.

In conclusion, while the sight of these horned rabbits may evoke shock or curiosity, they are merely a natural occurrence driven by a benign virus. As the fascination continues to spread, it serves as a reminder of the wonders and complexities of wildlife and the importance of understanding the natural world around us.
