SPV linked hornlike growths seen in Colorado rabbits

Wild rabbits in northern Colorado show hornlike growths caused by a summer virus, with officials saying there is no risk to humans.

Colorado rabbits develop hornlike growths linked to a summer virus

Residents in northern Colorado reported seeing wild rabbits with black horns and tentacle like growths on their faces. Wildlife officials identified the problem as Shope papilloma virus, a virus common in summer months that spreads through fleas or ticks. The affected rabbits are usually cottontails, and the wartlike growths can look horned if they grow longer.

Officials note there is no risk of the virus passing to humans or other animals. Most infected rabbits survive the illness and the growths typically fade over time. Domestic rabbits kept outside can contract the virus from insects or from contact with infected wild rabbits, so people should avoid touching wild rabbits and keep pets away. If a rabbit dies on private property, wearing gloves is advised and local wildlife authorities should be contacted for disposal guidance.

The sight of hornlike growths on wild rabbits highlights how wildlife diseases can become local stories quickly. The focus is as much on how people react as on the biology, and clear guidance from wildlife officials helps prevent unnecessary fear while directing actions for pet owners. This case shows the value of water-tight public messaging when science points to a non threat to people.

Beyond the immediate case, the episode raises questions about seasonal wildlife health monitoring and how information spreads online. It also underscores the need for ongoing surveillance and public education so communities can distinguish real risks from striking but harmless signs, encouraging calm, informed behavior rather than panic.

Highlights

Ongoing monitoring will clarify how common this pattern is this season and what it means for local wildlife health.
