What is Rabbit Hemorrhagic Disease (RHD)?

Rabbit Hemorrhagic Disease (RHD) is a highly contagious viral infection in rabbits, characterized by its short incubation period and almost 100% mortality rate. The causative agent is known as the Rabbit Hemorrhagic Disease Virus. This disease predominantly affects young adult rabbits during the winter and spring months, although nursing and weaned kits exhibit a higher level of immunity.

RHD is primarily transmitted through respiratory and digestive routes. Affected rabbits may exhibit symptoms such as anal relaxation, with feces coated in a pale yellow, jellylike substance, which can contaminate the fur around the anus. This is a distinctive symptom that can help differentiate RHD from other diseases.

What are the Symptoms of Rabbit Hemorrhagic Disease?

The incubation period for RHD is quite short, with rabbits showing symptoms within 20 to 48 hours after exposure. The symptoms can be categorized into four types based on the duration of the disease:

1. Acute, Severe Type: Rabbits may suddenly die without any warning, with some emitting a scream before death.

2. Acute Type: Symptoms include a high fever of 4142 degrees Celsius, accompanied by a lack of energy, decreased appetite, increased thirst, rapid breathing, and a rapid heartbeat. Some rabbits may exhibit erratic behavior, such as thrashing, ramming into the cage, and biting the cage bars, along with paddling movements and tremors. Death usually occurs 68 hours after the onset of symptoms, with foamlike blood around the nostrils and ears, and a yellowish secretion on the feces.

3. Chronic Type: The disease course typically lasts for 3 months or less. Rabbits may experience a high fever, lack of energy, decreased appetite, weight loss, rough and dull fur, and increased thirst. As the disease progresses, the rabbit's temperature may return to normal, and appetite issues may improve. Some rabbits may recover if they survive this stage.

4. Depressed Type: Rabbits show signs of depression and decreased vitality, with no other prominent symptoms.

Prevention and Control Measures for Rabbit Hemorrhagic Disease

As of now, there is no specific treatment for RHD. Most cases are introduced from other rabbit farms, primarily through contaminated feed, water, and bedding. Therefore, prevention is the key to managing RHD.

1. Vaccination: It is recommended that rabbit owners vaccinate their rabbits annually during the spring and autumn seasons. The vaccination process is straightforward, involving a single 1ml injection under the skin of the neck. This vaccination provides immunity for up to six months, making it a crucial preventive measure.

2. Sanitation: In the event of an outbreak in nearby rabbit farms, it is essential to ensure the safety of your rabbits' drinking water and food. You can use 1% sodium hydroxide to disinfect the rabbitry, effectively inactivating the RHD virus.

3. Heat Sensitivity: RHD viruses are sensitive to heat. At temperatures of 40°C or 37°C, a 0.4% formaldehyde solution can render the virus nonpathogenic.
