What is the rabies virus?
Rabies is a viral disease of warm-blooded animals that can be transmitted to humans. It is caused by a virus of the Rhabdoviridae family, which attacks the central nervous system and eventually affects the brain. Rabies is almost always fatal in animals and people once symptoms occur.
How is rabies transmitted between animals and humans?
The virus is transmitted through close contact with the saliva of infected animals, most often by a bite or scratch. It can also be transmitted by licks on broken skin or mucous membranes, such as those in the eyes, nasal cavity or mouth. In very rare cases, person-to-person transmission has occurred when saliva droplets became aerial. Bat bites can inflict small wounds and go unnoticed.
Who is at risk of being infected by rabies?
The rabies virus can infect any mammal. In North America, it occurs mainly in foxes, skunks, bats and raccoons, and can spread to domestic livestock and pets. In B.C. however, the only carrier of rabies is bats; no raccoons or skunks in B.C. have ever transmitted rabies.
How common is rabies in bats in B.C.?
It is estimated that one per cent of bats in the wild in B.C. carry rabies. In June 2004, four skunks in Stanley Park in Vancouver tested positive for the rabies virus. However, it was discovered that they all carried the bat strain of rabies; likely they had all been in contact with a rabid bat.
Cases of human rabies infection in Canada
In the past 20 years, three people in Canada died of rabies infection, one in Quebec (2000) and two in British Columbia (2003, 2019). These were the first cases of human rabies in Canada since 1985.
The most likely sources of infection for both individuals were unrecognized bat exposures. Without wound cleansing or post-exposure vaccinations, the potential incidence of rabies in exposed humans can be very high.
Does my pet need a rabies vaccine?
Dogs and cats account for fewer than 5 percent of all animal rabies cases in Canada. However, rabies presents a serious public health risk, and even indoor pets could come in contact with a bat. Some pets also need the vaccine for travel. Ask your vet whether your pet should be vaccinated.
What if my pet brings a bat home?
If your pet brings home a bat you should take your pet to a veterinarian. If the bat is available, your vet may send it for rabies testing. Additionally, your vet may vaccinate your pet against rabies and/or ask you to keep your pet in your home for several months to see if they develop signs of rabies.
If any person in your household has touched a bat with bare skin, seek medical attention from a doctor or local public health unit immediately.
What will happen to the bat?
The bat may be euthanized and sent for testing. As of April 1, 2014, CFIA veterinary inspectors are no longer involved in species collection activities. However, CFIA continues to perform and cover the cost for rabies laboratory testing involving domestic and wild animals and humans. This is vital as once the symptoms of rabies (flu-like including fever, headache, fatigue, progressing to GI and CNS problems) start to appear, there is no treatment and the disease is almost always fatal. However, wound cleansing and immunizations, done as soon as possible after suspected contact with an animal, can prevent the onset of rabies in virtually 100 percent of exposures.
What to do if there has been contact with a bat
If treatment is given promptly after being exposed to (any bare skin contact) or bitten by a bat, the illness may be prevented by taking the following actions:
- Immediately wash the wound or exposed surface with soap and water for 10 minutes and cover the area with a clean bandage.
- Remove any clothing that may have been contaminated.
- Immediately call your doctor and local health authority for advice.
Please contact your veterinarian to have your pet vaccinated and discuss whether a period of isolation/ observation is required for your pet. If the bat is available, your veterinarian may send it for rabies testing.
