According to the Wyoming Livestock Board, a wild eastern cottontail has tested positive for Rabbit Hemorrhagic Disease Virus 2 in Albany County.

The disease is a viral pathogen that causes sudden death in rabbits and can be spread through direct contact with infected rabbits, meat or fur or materials that come in contact with those carriers. It is only known to affect rabbits, both wild and domestic. It is highly contagious, fatal and is not related to coronavirus. It is not known to infect non-rabbit domestic pets, humans or livestock.

The virus was previously identified in New Mexico, Texas, Colorado, Nevada, Arizona and Utah.

There are no licensed vaccines produced in the U.S, but the process is underway for importing two vaccines. Accredited veterinarians may import a vaccine with approval by the state veterinarian and the USDA.

The virus could seriously impact the pet rabbit industry, 4-H and FFA projects, and academic, industrial or hobby groups such as laboratories, exhibitions, pelt and hunting.

Rabbit owners/breeders are advised to tighten biosecurity, ensuring their stock does not come in contact with wild rabbits, limiting introduction of new rabbits to the colony and barring visitors from the facility. Additionally, good measures for the owners include hand washing before and after handling animals, change clothing and footwear and not sharing equipment— like water bottles or containers — with other rabbit owners. 

For more information about this disease rabbit owners should contact their own veterinarian.
