Rabies is a fatal viral disease that can affect all mammals, and has become endemic in the dog populations of many parts of Indonesia. It arrived in Bali in late 2008 from a neighbouring island and quickly spread around the island.
Bali was rabies free until an infected dog came to the island from Flores in 2008. Since then, at least 137 people have died and many thousands of dogs have been killed in the attempt to eradicate the disease. Thanks to the amazing work done by the Bali Animal Welfare Association's vaccination program and the continued efforts of the government, the battle against rabies is slowly being won. However, the virus is still around and will pose a serious and ongoing threat until it is completely eradicated.
It is vital for the safety of you and your family that all your pet dogs and cats are immune to rabies. To achieve this they need to be vaccinated with an internationally recognised vaccine that is correctly stored and correctly administered according to the manufacturer’s guidelines.
Almost all of the human cases in Asia and Africa are due to dog bites; bat rabies is seldom documented, unlike in the Americas.
Unfortunately there is no reliable ‘in vivo’ test for rabies in animals in Bali. If a dog (or cat) is suspected of having rabies, it is either euthanased immediately and a sample of brain tissue sent to the laboratory for testing, or it is quarantined for 10 days.
If an animal is still alive 10 days after first exhibiting symptoms, then it does not have rabies. If you encounter a dog or cat in Bali showing any of the symptoms described below, whether it is your own pet, a friend’s pet or a street animal, do not wait and see how things develop; you are putting the lives of yourself and others at risk.
Please call Sunset Vet or alternatively for street dogs & cats, call the Bali Animal Welfare Association 24hr rabies hotline on 081-1389004.
Symptoms of rabies
- Behaviour that is out of character such as aggression or apprehension
- Restlessness, disorientation or aimless wandering
- Odd sitting position
- Change in tone or nature of bark/miaow
- Reluctance to drink or eat
- Dropped jaw
- Weakness or paralysis
Treatment of Rabies
Unfortunately rabies is fatal and there is no successful treatment, in both animals and humans. Due to the risk to human health, animals that are suspected of having rabies should be either euthanased or quarantined in a secure environment with supportive veterinary care.
If your pet gets bitten by another potentially rabid dog (i.e. a dog of unknown rabies vaccination status), the wound must be immediately flushed and washed for a minimum of 15 minutes with soap and water or povidone iodine, to kill any rabies virus that has not yet entered the body.
Although there is no treatment for rabies once an animal starts showing symptoms, it can be prevented by either pre-exposure or post-exposure vaccination (exposure = a bite by a rabid animal). However, if an unvaccinated dog is bitten by another dog that is likely to be rabid, then even aggressive flushing of the wound and post-exposure vaccination might not be enough to stop rabies being transmitted. This is because it takes several weeks for the vaccine to stimulate the body into producing antibodies, by which time it could be too late. We do not have the expensive ‘ready-made’ antibodies for dogs that we have for humans (known as rabies immunoglobulin) that can bridge this gap.Back to top
Prevention of Rabies
With rabies being so deadly, vaccine failure is simply not an option. Therefore when getting your dog or cat vaccinated for rabies, make sure it is an internationally reputable vaccine (usually best to stick to the ones manufactured by the large pharmaceutical companies) that has been stored correctly and is not out of date. Examples of reputable vaccines are Rabisin® (Merial Animal Health) and Defensor® (Pfizer Animal Health). The protocol that Sunset Vet recommends is the one according to the manufacturer’s datasheet:
- For Defensor®, a single 1ml dose is given subcutaneously at 3 months of age or older, followed by a repeat dose 1 year later, with a subsequent booster every 3 years.
- For Rabisin®, a single 1ml dose is given subcutaneously at 3 months of age or older, followed by a booster every 2 years.
Immunity has been demonstrated 1 month after initial vaccination, and probably occurs sooner although this has not been clinically proven. The manufacturers recommend avoiding giving the rabies vaccine within 2 weeks of giving other vaccines if possible to ensure the maximum immune response. The rabies vaccine is thought to be safe to give to pregnant animals.Get in touch for an appointment Back to top
How is rabies transmitted?
The rabies virus enters the body via wounds (e.g. a dog bite) or direct contact with mucosal surfaces. It cannot cross intact skin. The virus then travels up the nerves to the central nervous system, and once it reaches the brain it is almost always fatal.
The incubation period in both humans and animals can range widely from 2 weeks up to several years (average 2-3 months), with the incubation period being shorter the nearer the entry point is to the central nervous system. Therefore a bite to the face or neck has a much shorter incubation period than a bite to the foot. Once the virus has reached the brain, it spreads to other sites such as the salivary glands.Back to top
What are the symptoms of rabies?
Dogs and cats with rabies generally present in one of two ways – with paralytic rabies or with furious rabies. The paralytic stage can occur after the furious stage, or the animal can skip the furious stage completely and display only the paralytic phase.
Whichever form a dog or cat has, once it starts showing symptoms of rabies, it will die within 10 days. Symptoms to look out for are:
- Change in behaviour; friendly animals become shy or nervous, or aggressive animals become docile
- Change in the tone of the bark (dogs) or miaow (cat)
- Exaggerated response to visual or auditory stimuli
- Roaming, running for no apparent reason
- Strange sitting position
- Disorientation, progressing to seizures
- Reluctance to drink (hydrophobia) and fear of drafts (aerophobia)
- Laboured breathing
- General weakness, progressing to paralysis
Are there any adverse effects vaccinating my dog or cat?
Vaccination may sometimes induce a local reaction, as a small nodule at the injection site (usually 2-3cm diameter, persisting up to 10-15 days). Vaccination may exceptionally induce an anaphylactic (hypersensitivity) reaction; this can usually be managed in a clinic setting.Back to top
