Rabbit hemorrhagic disease (RHD) can be a terrifying prospect for rabbit owners. It's a swift-moving, often fatal virus that affects both wild and domestic rabbits. Understanding this disease is crucial for anyone who wants to protect their fluffy companions. In this post, we'll break down the essentials of RHD, offering you the knowledge you need to safeguard your rabbits.
Understanding Rabbit Hemorrhagic Disease
Rabbit hemorrhagic disease, also known as viral hemorrhagic disease (VHD) or rabbit calicivirus disease (RCD), is a highly contagious viral infection caused by the rabbit hemorrhagic disease virus (RHDV). It was first observed in China in 1984 and has since spread to various parts of the world, but is new to Alberta. The disease primarily affects rabbits over two months old and is characterized by its rapid onset and high mortality rate.
Recognizing the Symptoms of RHD
Early detection is crucial. However, RHD symptoms can be difficult to spot because the disease progresses rapidly, often resulting in sudden death without any visible warning signs. Common symptoms include high fever, lethargy, appetite loss, difficulty breathing, and bleeding from the nose or mouth. If you notice any of these signs in your rabbit, seek veterinary care immediately to improve their chances of survival.
How RHD Spreads
The virus that causes RHD is incredibly resilient and can spread through direct contact with infected rabbits or indirect contact via contaminated objects, clothing, or food. Even insects like flies can carry the virus from one rabbit to another. Understanding these transmission pathways is key to implementing effective preventive measures in your home or rabbitry.
Protecting Your Rabbits from RHD
Prevention is your best defense against RHD. Vaccination is widely regarded as the most effective way to protect rabbits, and many veterinarians recommend it for all rabbits over six weeks old. Additionally, quarantining new rabbits, disinfecting enclosures regularly, and keeping your rabbits indoors—can significantly reduce the risk of infection.
It will be more likely that an outbreak starts in a wild population. If this is in your area, not only should you keep your rabbit indoors , you should be mindful of tracking the virus yourself. Keep shoes outside and when doing garden or yard work, wash your hands after. Your local exotic vet, local humane society, and news stations would be the best resources to notify you of an outbreak in your area.
The Role of Vaccination in RHD Prevention
Vaccination is an essential tool in the fight against RHD. Vaccines are available for both RHDV1 and RHDV2 strains, offering protection against the most common forms of the virus. Routine vaccination not only protects your rabbits but also helps limit the spread of the disease within the community. Consult your veterinarian to create a vaccination schedule tailored to your rabbits' needs.
What to Do If an Outbreak Occurs
In the unfortunate event of an RHD outbreak, act quickly to contain the spread. Isolate any infected rabbits immediately and follow your veterinarian's advice on care and treatment. Inform local authorities or a wildlife service about the outbreak, as they may have protocols in place to manage the disease and prevent further transmission.
Staying Updated on RHD Developments
RHD is an evolving disease, and new information about its management and prevention is continually emerging. Stay informed by following reputable sources such as veterinary organizations and rabbit welfare groups. Joining online communities of rabbit enthusiasts can also provide support and share the latest news and resources related to RHD.
