Rabies is a serious illness. By the time the symptoms of rabies have become apparent, it is generally too late to save the patient.

Rabies is a virulent killer that can spread using any mammal species as a host.1

What is rabies?

The majority of human rabies cases are the result of a bite from a dog infected with the virus.

Rabies is a viral infection spread via saliva. If someone presents with rabies symptoms, it is almost always fatal. In countries where stray dogs are present in large numbers, they are the biggest rabies threat.

Predominantly, in the US, rabies is spread by raccoons, coyotes, bats, skunks and foxes.2 Bats carrying rabies have been found in all 48 contiguous states.

Dr. Joseph Lennox Pawan first discovered animal-to-human transmission of rabies in the vampire bat in Trinidad in 1932.3

It is now known that any mammal can harbor and transmit the virus. However, smaller mammals such as rodents very rarely become infected or transmit rabies.

Symptoms of rabies

The symptoms of rabies can present themselves just a few days after a bite, or they might take as long as 12 weeks. Some rare cases report a number of years between the bite and the onset of symptoms.

The closer the bite is to your brain, the quicker the effects are likely to appear.4

If you are bitten by a wild animal, it is essential that you seek medical advice as soon as possible.

When the initial symptoms of rabies occur, they can be similar to flu and last 2-12 days, becoming progressively stronger.

From the early flu-like symptoms, the condition worsens and symptoms can include the following:

  • Anxiety
  • Fever
  • Headache
  • Nausea
  • Confusion
  • Hyperactivity
  • Excess salivation
  • Fear of water (hydrophobia) due to difficulty in swallowing
  • Hallucinations
  • Priapism (permanent erection)
  • Photophobia
  • Nightmares
  • Insomnia
  • Partial paralysis.
