Rabbit Hemorrhagic Disease Virus (RHDV-2) in Colorado: Facts and Concerns

Colorado's rabbit population faces a significant threat from the highly contagious Rabbit Hemorrhagic Disease Virus (RHDV-2). This devastating viral disease is causing widespread concern among wildlife officials, pet rabbit owners, and anyone who appreciates the ecological role of rabbits in Colorado's diverse ecosystem. Understanding RHDV-2, its impact, and the preventative measures being taken is crucial.

What is RHDV-2?

RHDV-2 is a highly lethal virus that affects rabbits and hares. It's a calicivirus, meaning it's related to other viruses that cause illnesses in various animals. Unlike some diseases, RHDV-2 doesn't typically affect other species, including humans, dogs, and cats. However, direct contact with infected rabbits or their bodily fluids should be avoided.

Symptoms and Transmission:

The virus is incredibly contagious and spreads rapidly through direct contact with infected rabbits, their bodily fluids (including saliva, feces, and urine), contaminated food and water sources, and even indirectly through vectors like insects. Symptoms can appear suddenly and include:

• Lethargy and weakness: The rabbit may seem unusually tired or sluggish.
• Loss of appetite: A significant decrease in food intake is a key indicator.
• Fever: Although difficult to detect in rabbits, fever is often present.
• Bloody nasal discharge: This is a particularly alarming symptom.
• Sudden death: RHDV-2 often leads to rapid death with minimal warning signs.

Impact on Colorado's Wildlife:

The impact of RHDV-2 on Colorado's wild rabbit populations is a major concern. Rabbits play a crucial role in the state's delicate ecosystem, serving as a vital food source for predators like coyotes and hawks. A significant decline in rabbit populations could have cascading effects throughout the food chain. Furthermore, certain rabbit species are more vulnerable than others, potentially leading to imbalances within the ecosystem. [Link to Colorado Parks and Wildlife website regarding wildlife impacts].

Protecting Your Pet Rabbits:

Pet rabbit owners need to be vigilant. The best defense is prevention. Here's what you can do:

• Vaccination: Vaccines are available for RHDV-2 and are highly effective. Consult your veterinarian immediately about vaccination for your pet rabbits.
• Biosecurity: Strict biosecurity measures are crucial. This includes avoiding contact with wild rabbits, properly cleaning and disinfecting cages and equipment, and carefully managing the introduction of new animals into your home.
• Quarantine: Quarantine any new rabbits for at least 30 days before introducing them to your existing pets.
• Hygiene: Practice excellent hygiene when handling your rabbits and their environment.

What is being done?

Colorado Parks and Wildlife (CPW) is actively monitoring the spread of RHDV-2 and working to mitigate its impact. This includes research, public awareness campaigns, and collaboration with other agencies and researchers. [Link to CPW's RHDV-2 information page].

Conclusion:

RHDV-2 poses a serious threat to Colorado's rabbit population. While there is no immediate cure, preventative measures such as vaccination and strict biosecurity are essential to protect both wild and domestic rabbits. Staying informed and taking proactive steps is crucial in minimizing the devastating effects of this virus. Remember to contact your veterinarian or Colorado Parks and Wildlife with any concerns.
