Rabbit owners often worry about viruses that can threaten the health of their furry companions. While rabbits are generally hardy animals, certain viral diseases can be fatal if not prevented. The most well-known and dangerous rabbit virus is Rabbit Hemorrhagic Disease Virus (RHDV), sometimes called rabbit calicivirus. In this guide, we’ll explain what rabbit viruses are, how they spread, what symptoms to look out for, and—most importantly—how to protect your rabbits.
Quick Overview – The Most Serious Rabbit Virus
- Rabbit Hemorrhagic Disease Virus (RHDV): A highly contagious and often fatal disease affecting rabbits worldwide.
- Myxomatosis: Another viral disease caused by the myxoma virus, still present in some regions.
- Lesser-known viruses: Cold-like viruses and minor respiratory infections exist, but RHDV and myxomatosis are the main threats.
How Rabbit Viruses Spread
Rabbit viruses are extremely contagious. Here are the most common ways they spread:
- Direct contact: With infected rabbits (wild or domestic).
- Contaminated surfaces: Hutches, food bowls, toys, or bedding.
- Insects: Flies, fleas, and mosquitoes can carry viruses from rabbit to rabbit.
- Human transfer: Owners can accidentally bring virus particles into the rabbit’s environment on shoes, clothing, or hands.
- Wildlife: Wild rabbits are often carriers and can infect outdoor pets.
Symptoms of Rabbit Viruses
RHDV can sometimes kill without warning, but common symptoms include:
- Sudden loss of appetite
- Lethargy or unusual behavior
- Fever or difficulty breathing
- Seizures or paralysis
- Bleeding from the nose or mouth (in severe cases)
Important: These symptoms can appear suddenly. If you see them, contact a rabbit-savvy veterinarian immediately.
How to Protect Your Rabbits from Viruses
There’s no cure for RHDV or myxomatosis, but prevention is possible:
- Vaccination: In many regions, vaccines are available and strongly recommended.
- Biosecurity: Wash hands, disinfect equipment, and avoid contact between your pet rabbits and wild rabbits.
- Insect control: Use mosquito screens, flea prevention, and fly control around hutches.
- Safe housing: Keep outdoor rabbits in secure hutches that minimize contact with wildlife and insects.
- Proper size housing: Overcrowded hutches increase stress and disease risk. Always check the Rabbit Cage Size Calculator to make sure your setup gives rabbits enough room to stay healthy.

FAQ
Is there a cure for RHDV?
No. There is no cure once a rabbit contracts Rabbit Hemorrhagic Disease Virus. Vaccination and prevention are the only protection.
Should I vaccinate my rabbit?
Yes, if vaccines are available in your country. In many regions, vaccinations are the only effective defense against rabbit viruses.
Can indoor rabbits get viruses too?
Yes. Viruses can be carried indoors on shoes, clothing, or by insects like mosquitoes. Even indoor rabbits should be vaccinated if possible.
What’s the difference between RHDV1 and RHDV2?
Both are deadly strains of Rabbit Hemorrhagic Disease Virus. RHDV2 is newer and has spread rapidly worldwide. Vaccination should cover both strains.
Conclusion
Rabbit viruses are a serious threat, but with awareness and prevention, you can protect your pets. Vaccination, secure housing, good hygiene, and a proper diet all play key roles in keeping rabbits healthy. Since safe housing is one of the most important protections, always make sure your rabbits have enough space while staying secure.
