Rabbit Hemorrhagic Disease Virus (RHDV2) in Colorado: What You Need to Know

A deadly virus threatens Colorado's rabbit population – and yours. Rabbit Hemorrhagic Disease Virus 2 (RHDV2) has been detected in Colorado, sparking concerns among wildlife officials, pet owners, and agricultural producers alike. This highly contagious and often fatal disease requires immediate attention and proactive measures to mitigate its spread. Understanding the risks and preventative measures is crucial for protecting both wild and domestic rabbits.

What is RHDV2?

RHDV2 is a highly contagious viral disease that affects rabbits. It's caused by a calicivirus and spreads rapidly through direct contact with infected rabbits, contaminated materials (like feed, water, or equipment), and even insect vectors like flies. The virus attacks the liver, causing internal hemorrhaging and often resulting in sudden death. Symptoms can include lethargy, loss of appetite, difficulty breathing, and bloody nasal discharge, although many rabbits die suddenly with few noticeable symptoms. Unfortunately, there is currently no known cure for RHDV2.

The Situation in Colorado:

The detection of RHDV2 in Colorado represents a significant threat to the state's diverse rabbit population, encompassing both wild rabbits like jackrabbits and cottontails, and domestic breeds. The Colorado Parks and Wildlife (CPW) is actively monitoring the situation and working to contain the spread. They've established [link to CPW RHDV2 page, if available]. However, the virus's rapid transmission necessitates a community-wide effort to prevent further outbreaks.

Who is at Risk?

• Wild Rabbits: Wild rabbit populations are particularly vulnerable due to the high density of animals and the potential for rapid viral spread.
• Domestic Rabbits: Pet rabbits and those raised for agricultural purposes are also at high risk of infection. Even rabbits kept indoors are not completely safe, as the virus can be transmitted through contaminated clothing or equipment.
• Rabbit Owners: Anyone who owns or handles rabbits needs to be aware of the risks and take appropriate precautions.

Protecting Your Rabbits:

The best defense against RHDV2 is prevention. Here's what you can do:

• Biosecurity: Implement strict biosecurity measures to prevent contact between your rabbits and potentially infected animals or materials. This includes disinfecting cages, equipment, and clothing regularly. Use approved disinfectants effective against caliciviruses.
• Vaccination: While not yet widely available, RHDV2 vaccines are becoming increasingly accessible. Consult with your veterinarian about vaccination options for your rabbits. Early vaccination is key to protecting your pets.
• Quarantine: If you suspect your rabbit may be infected, immediately isolate it from other rabbits to prevent the spread of the virus.
• Hygiene: Practice excellent hygiene when handling rabbits. Wash your hands thoroughly before and after handling your pets and any rabbit-related materials.
• Vector Control: Control insect populations around your rabbit housing to reduce the risk of transmission via vectors.

What to Do if You Suspect an Infection:

If you suspect your rabbit is infected with RHDV2, contact your veterinarian immediately. Early detection and reporting are crucial for helping wildlife officials track the spread of the virus and implement effective control measures. Do not attempt to handle or dispose of a deceased rabbit yourself; contact your local animal control or wildlife authorities for guidance.

Staying Informed:

Stay informed about the latest developments regarding RHDV2 in Colorado by regularly checking the CPW website and other reliable sources of information. Understanding this threat and taking proactive steps is vital in protecting Colorado's rabbit populations.

Call to Action: Help protect Colorado's rabbits! Share this information with fellow rabbit owners and anyone who might encounter wild rabbits. Your vigilance can make a difference in controlling the spread of this deadly disease.
