BC is advising rabbit owners in the Capital Regional District to take precautions with their pet rabbits after two feral rabbits in Saanich died from a highly infectious virus.
Testing has confirmed the presence of rabbit hemorrhagic disease, caused by a calicivirus. It is the second year in a row that the virus has been found in Island rabbits, but the source of the virus is unknown.
Rabbit hemorrhagic disease is an extremely infectious and lethal disease that is exclusive to rabbits. Humans and other animals, including dogs and cats, cannot be infected. The strain of the virus seen last year affects only European rabbits and is not known to affect native North American rabbits.
Pet owners should monitor their rabbits daily for signs of illness and contact their veterinarian immediately with any concerns. The virus causes hemorrhages by affecting the blood vessels and attacking the liver and other organs. Most affected rabbits die suddenly, but can show signs of listlessness, lack of co-ordination, behaviour changes or trouble breathing before death. There is often bleeding from the nose at the time of death. Once infected, signs of illness occur quickly, usually within one to nine days.
While there is no threat to humans, rabbit owners should avoid bringing the virus home by practising excellent hygiene when handling their animals and staying away from areas where the disease has occurred.
Vaccines to protect pet rabbits from rabbit hemorrhagic disease are available through veterinary clinics around the province.
Rabbit owners who want more information about how to keep their pets safe can consult with their veterinarian regarding vaccinations and review an SPCA factsheet on rabbit hemorrhagic disease: https://spca.bc.ca/wp-content/uploads/Rabbit-Hemorrhagic-Disease-Information-Sheet-for-Rabbit-Guardians.pdf
