Rabbit owners and enthusiasts often come across the term “RHD” when researching about rabbit health, but what exactly does it mean? RHD, or Rabbit Hemorrhagic Disease, is a highly contagious and deadly viral disease that affects rabbits worldwide. It’s essential to understand this disease, its symptoms, and prevention methods to ensure the health and well-being of your beloved pets.
What is RHD in Rabbits?
RHD is a viral disease caused by the Rabbit Hemorrhagic Disease Virus (RHDV). It’s a highly infectious disease that affects rabbits of all ages, breeds, and sizes. The virus attacks the liver and spleen, causing massive internal bleeding, which ultimately leads to the death of the infected rabbit.
Why is RHD a Significant Concern?
RHD is a significant concern for rabbit owners and breeders because of its high mortality rate, which can be as high as 90% in some cases. The disease spreads rapidly through direct contact with an infected rabbit, contaminated food and water, or even through indirect contact with contaminated surfaces or utensils. This makes it crucial to take preventive measures to protect your rabbits from this deadly disease.
In the following sections, we’ll delve deeper into the symptoms, diagnosis, treatment, and prevention of RHD in rabbits, as well as discuss the importance of vaccination and biosecurity measures to keep your rabbits safe and healthy.
What is RhD in Rabbits?
RhD, also known as Rabbit Hemorrhagic Disease, is a highly infectious and deadly viral disease that affects rabbits. It is a significant concern for rabbit breeders, owners, and veterinarians worldwide. In this article, we will delve into the details of RhD in rabbits, its causes, symptoms, diagnosis, treatment, and prevention.
What Causes RhD in Rabbits?
RhD is caused by a calicivirus, which is a type of virus that affects the gastrointestinal tract of rabbits. The virus is highly contagious and can be spread through:
- Direct contact with an infected rabbit’s feces, urine, or saliva
- Indirect contact with contaminated food, water, or bedding
- Airborne transmission through coughing or sneezing
- Contact with contaminated fomites, such as cages, utensils, or clothing
The virus can survive for a long time outside the host, making it a significant challenge to control and prevent the spread of the disease. (See Also: Does Catnip Affect Rabbits)
Symptoms of RhD in Rabbits
The symptoms of RhD in rabbits can vary in severity, but they typically appear within 1-5 days after infection. The most common symptoms include:
- Severe diarrhea, which is often bloody and watery
- Loss of appetite and lethargy
- Fever, which can be high
- Respiratory distress, such as difficulty breathing and rapid breathing rate
- Abdominal pain, which can cause rabbits to become restless and vocalize
- Bloody urine or hematuria
In severe cases, rabbits may experience:
- Seizures or convulsions
- Coma or death
Diagnosis of RhD in Rabbits
Diagnosing RhD in rabbits can be challenging, as the symptoms are similar to those of other diseases. A definitive diagnosis typically requires:
- PCR (Polymerase Chain Reaction) testing of feces, blood, or tissue samples
- ELISA (Enzyme-Linked Immunosorbent Assay) testing of blood samples
- Post-mortem examination of the rabbit’s body
A veterinarian may also perform a physical examination, take a complete medical history, and rule out other diseases that may cause similar symptoms.
Treatment of RhD in Rabbits
Unfortunately, there is no specific treatment for RhD in rabbits. The disease is often fatal, and treatment is primarily focused on managing the symptoms and supporting the rabbit’s body functions. This may include:
- Fluid therapy to prevent dehydration
- Antibiotics to prevent secondary bacterial infections
- Pain management to alleviate abdominal pain and discomfort
- Supportive care, such as providing a warm, comfortable environment and offering a nutritious diet
In some cases, veterinarians may use experimental treatments, such as antiviral medications or immunoglobulins, but their effectiveness is still uncertain.
Prevention of RhD in Rabbits
Preventing RhD in rabbits is crucial, as the disease is highly contagious and deadly. Here are some measures to prevent the spread of the disease:
- Vaccination: Vaccinating rabbits against RhD can provide protection against the disease. However, the effectiveness of the vaccine may vary depending on the strain of the virus and the individual rabbit’s immune response.
- Quarantine and isolation: Isolating new rabbits or those that have been exposed to the virus can help prevent the spread of the disease.
- Proper hygiene and sanitation: Cleaning and disinfecting cages, utensils, and equipment regularly can help reduce the risk of transmission.
- Reducing stress: Stress can weaken a rabbit’s immune system, making it more susceptible to infection. Providing a stress-free environment and ensuring rabbits receive regular exercise and social interaction can help boost their immune system.
- Monitoring for symptoms: Regularly monitoring rabbits for symptoms of RhD and seeking veterinary care promptly if any signs of illness are observed can help prevent the spread of the disease.
Control and Eradication of RhD Outbreaks
In the event of an RhD outbreak, it is essential to take immediate action to control and eradicate the disease. This may involve:
- Isolating affected rabbits to prevent further transmission
- Disinfecting and cleaning all cages, utensils, and equipment
- Vaccinating all rabbits in the affected area
- Implementing strict biosecurity measures, such as restricting access to the affected area and requiring visitors to wear protective clothing
- Collaborating with local authorities and veterinarians to contain and eradicate the outbreak
Conclusion
RhD is a highly infectious and deadly disease that affects rabbits. It is essential to understand the causes, symptoms, diagnosis, treatment, and prevention of the disease to protect rabbits from this devastating illness. By taking proactive measures to prevent the spread of RhD, rabbit owners and breeders can help reduce the risk of infection and protect their beloved pets.

RHD, or Rabbit Hemorrhagic Disease, is a highly contagious and deadly viral disease that affects rabbits. It is caused by a calicivirus that targets the liver and causes internal bleeding, leading to rapid death.
How is RHD transmitted in rabbits?
RHD can be transmitted through direct contact with an infected rabbit’s feces, urine, or saliva, as well as through indirect contact with contaminated food, water, or surfaces. It can also be spread by insects, such as flies, and through contaminated bedding or equipment.
What are the symptoms of RHD in rabbits?
The symptoms of RHD can vary, but they typically include lethargy, loss of appetite, fever, and difficulty breathing. In some cases, rabbits may exhibit no symptoms at all, while in others, they may show sudden and severe symptoms, such as bleeding from the nose or mouth.
Is there a vaccine available for RHD in rabbits?
Yes, there are vaccines available to protect rabbits against RHD. The vaccine is typically given to rabbits at 10-12 weeks of age, and boosters are recommended every 6-12 months. However, it’s essential to consult with a veterinarian to determine the best vaccination schedule for your rabbit.
