Rabies - Frequently Asked Questions

 

Learn the answers to frequently asked questions about rabies.

What is rabies?

Rabies is a disease in animals caused by a virus that can spread to humans. Infection with the rabies virus leads to acute viral encephalomyelitis (inflammation of the brain and spinal cord).

If you are exposed to rabies, you need to get treatment right away. Once symptoms begin, the rabies virus is almost always fatal.

Rabies can infect any mammal, including humans, pets, wildlife and livestock. The most common carriers of the rabies virus in Ontario are:

  • Bats
  • Raccoons
  • Foxes
  • Skunks

Birds, reptiles, amphibians and fish do not get rabies.

 

How does rabies spread?

Rabies is a virus that can spread from an infected mammal to any other mammal, including humans, pets, livestock and wildlife.

Rabies is spread through:

  • bites that break the skin;
  • saliva entering an open wound;
  • saliva entering the mouth, nose or eyes; or
  • direct contact with infected brain or nervous system tissue through broken skin or mucous membranes in the eyes, nose, or mouth.

The virus enters the nerves in the open wound or the mucous membranes and travels to the brain.

Rabies cannot be transmitted through contact with the blood, urine or feces of an infected animal.

 

What are the signs and symptoms of rabies?

In animals

  • wild animals acting friendly or tame
  • hiding in isolated areas and depression
  • loss of fear of humans, especially skunks (e.g., they do not run away when approached by humans or domestic animals)
  • paralysis, such as abnormal facial expressions, drooping heads, sagging jaws or paralyzed hind legs
  • extreme excitement and aggression
  • gnawing and biting their own legs
  • attacking objects or other animals
  • frothing at the mouth

In humans

Initial symptoms are usually flu-like with fever, headache and nausea. As the disease progresses, symptoms might include:

  • insomnia
  • anxiety
  • slight or partial paralysis
  • increased activity, restlessness
  • hallucinations
  • difficulty swallowing
  • fear of water

Once symptoms appear, rabies is almost always fatal.

 

How long does it take for symptoms of rabies to develop?

  • Animals: 2 weeks to many months
  • Humans: 3-8 weeks (in some cases, as early as 9 days and as long as 7 years after exposure)

The length of time depends on a number of factors including:

  • severity of the bite
  • location of bite
  • amount and the strain of the rabies virus
 

What should I do if I am bitten or scratched by an animal or had contact with wildlife?

  • If possible, collect the contact information of the animal’s owner/custodian (name, address and phone number).
  • Immediately wash any wound or mucous membranes with soap and water and remove any clothing that might be contaminated with saliva. Proper wound care after an animal bite can significantly reduce the risk of rabies.
  • Immediately contact your healthcare provider. They will treat any wounds and determine the need for post-exposure rabies treatment in consultation with Halton Region Public Health.
  • Notify your local Animal Control Services if necessary.
  • Call 311 to report the incident to Halton Region Public Health and a public health inspector will follow up with you to collect information, including:
    • Name and address of the pet owner, if applicable
    • Description of the animal
    • Information that will help to locate the animal

If you had contact with a bat, visit Bats & Rabies for more information.

 

How do I know if an animal had rabies when it bit or scratched me?

Animals infected with the rabies virus are only contagious for a short period of time before symptoms appear. Halton Region Public Health will take steps to determine if the animal had rabies when the bite, scratch or other exposure occurred.

Dogs, cats and ferrets are confined for a 10-day isolation period at a location approved by Halton Region Public Health. During this time, the animal is observed for signs or symptoms of rabies. Animals that are alive and healthy at the end of the 10-day period would not have transmitted rabies in their saliva at the time of the bite or scratch.

If the animal involved cannot be located and observed, you will be advised to consult with your healthcare provider about post-exposure rabies treatment.

 

Is there a vaccine to protect people against rabies?

Yes. There are 2 reasons for vaccination against rabies:

  • Pre-exposure vaccine: Given to certain travellers or people who work in a job that may expose them to rabies (e.g., veterinarians, laboratory workers handling the rabies virus, animal control).
  • Post-exposure vaccine: The need for rabies treatment following a potential rabies exposure is determined by the healthcare provider, in consultation with Halton Region Public Health.
 

What should I do if my pet had contact with wildlife?

If your pet has been in contact with wildlife, call your veterinarian immediately. For more information, visit Ontario's Rabies in pets webpage (external link).

 

How do I protect my family and pets from rabies?

  • Make sure your pet’s rabies vaccinations are up to date. You are required by law to vaccinate all of your cats and dogs over the age of three months.
  • Observe wildlife from a distance.
  • Teach children to avoid unfamiliar cats and dogs.
  • Don’t allow your pet to roam free; keep them indoors at night to prevent contact with wild animals.
  • Report all animal bites, scratches and possible exposures to Halton Region Public Health.
  • Talk to your healthcare provider about rabies pre-exposure vaccine if you work in a job that may expose you to rabies or plan to spend time in a country where rabies is common.

What is the Province of Ontario doing to control rabies in wildlife?

The Province works to control rabies in terrestrial (non-bat) wildlife by:

  • distributing baits for wildlife that contain rabies vaccine
  • trapping and vaccinating wildlife in high-risk areas
  • testing dead, sick or strange acting wildlife
  • conducting research to improve rabies control program effectiveness
