what is rabies

Rabies is a viral disease that attacks the brain and spinal cord and is almost always fatal once symptoms appear, but it is preventable if treated quickly after exposure.

What rabies is

Rabies is caused by a virus (rabies virus, a lyssavirus) that infects mammals, including humans, dogs, bats, foxes, raccoons, and skunks.

It is a zoonotic disease, meaning it spreads from animals to humans, and it causes acute inflammation of the brain (encephalitis) and sometimes the spinal cord.

How rabies spreads

Rabies usually spreads through the saliva of an infected animal, most often via a bite that breaks the skin.

Saliva can also transmit rabies if it gets into mucous membranes (eyes, mouth, nose) or an open wound or scratch.

  • Globally, most human rabies cases come from bites by infected dogs.
  • In countries like the U.S. and Canada, wild animals such as bats, raccoons, skunks, and foxes are more common sources.

Symptoms and forms

After a bite, there is usually a silent incubation period (often weeks to months) with no symptoms while the virus travels along the nerves toward the brain.

Early symptoms can be nonspecific, such as fever, headache, and tingling or pain at the bite site.

As the disease progresses, two main forms appear:

  • Furious rabies:
    • Agitation, anxiety, hallucinations, confusion, violent movements, sensitivity to light or sound.
* Difficulty swallowing and “hydrophobia” (panic or spasms when trying to drink).
  • Paralytic rabies:
    • Gradual muscle weakness and paralysis starting near the bite and spreading inward.
* Leads to coma and death.

Once these neurological symptoms start, rabies is almost always fatal, with a mortality rate over 99%.

Treatment and prevention

There is no effective cure after symptoms appear, which is why fast action after a possible exposure is critical.

However, rabies is preventable if you receive prompt post‑exposure prophylaxis (PEP) :

  1. Immediate, thorough washing of the wound with soap and plenty of water for at least 15 minutes.
  1. Quick medical evaluation to assess rabies risk based on the animal and the exposure.
  1. Rabies vaccine series, and in many cases rabies immune globulin injected near the wound and/or into a muscle.

People at higher risk (for example, veterinarians, animal handlers, certain lab workers, travelers to high‑risk regions) may receive pre‑exposure rabies vaccines.

Why rabies still matters today

Despite being fully preventable, rabies still kills tens of thousands of people each year, mostly in Asia and Africa where dog vaccination and access to PEP can be limited.

Large international campaigns focus on mass dog vaccination, education about dog bites, and improving access to vaccines to eliminate human deaths from dog‑mediated rabies.

If you or someone you know is bitten or scratched by a potentially rabid animal, seek medical care immediately—even if the wound seems minor.
