Rabies and Other Lyssaviruses: What Australians Need to Know

Rabies is a deadly but preventable disease. While Australia is free of classical rabies, we do have a related virus called Australian bat lyssavirus (ABLV). Both the rabies virus and other lyssaviruses can cause a severe brain infection (encephalitis) that is almost always fatal once symptoms appear.

Vaccination, safe wound care, and timely medical management are crucial in preventing rabies after potential exposure. Consulting your GP is a good first step.

What Is Rabies?

Rabies is a zoonotic disease (an infection that spreads from animals to humans). It is transmitted through saliva or nerve tissue of an infected animal, usually by:

  • Bites or scratches that break the skin

  • Saliva contacting broken skin or mucous membranes (eyes, mouth, nose)

Worldwide, rabies is most often linked to dog bites. In Australia, the main risk comes from bats, which may carry Australian bat lyssavirus (ABLV).

Who Is at Risk?

You may be at risk of rabies or other lyssaviruses if you are:

  • Working with bats (wildlife handlers, carers, researchers)

  • Travelling to rabies-enzootic regions (Asia, Africa, Central and South America)

  • Laboratory staff handling live rabies or lyssavirus samples

Even casual exposure — such as being scratched by a bat — can carry a risk. Children, intoxicated people, or anyone unable to describe what happened may be at higher risk of unnoticed exposure.

Rabies Vaccination in Australia

Pre-exposure Vaccination

Vaccination is recommended before exposure for:

  • Bat handlers and carers

  • Laboratory workers exposed to live virus

  • Some travellers, depending on risk assessment

Different schedules are available, ranging from 2 to 3 doses, given by either intramuscular or intradermal routes. Boosters may be needed for those with ongoing risk.

Post-exposure Vaccination

If you are potentially exposed to rabies or lyssaviruses:

  1. Immediately wash the wound with soap and water

  2. Apply an antiseptic such as povidone-iodine

  3. Seek urgent medical attention

Depending on the exposure type, you may require:

  • A full course of rabies vaccine

  • Human rabies immunoglobulin (HRIG) for severe exposures

  • Ongoing monitoring and follow-up

Categories of Exposure

The Australian Immunisation Handbook describes three levels of exposure:

Category Description Management
I – No exposure Touching or feeding animals, licks on intact skin No treatment needed
II – Exposure Minor scratches or abrasions without bleeding Rabies vaccine
III – Severe exposure Bites, transdermal scratches, saliva contact with mucous membranes, or any bat exposure Rabies vaccine + HRIG (if indicated)

Why Prevention Matters

Rabies is almost always fatal once symptoms start. The disease affects the brain and nervous system, leading to agitation, hallucinations, hydrophobia (fear of water), paralysis, and death.

Australia remains rabies-free in terrestrial animals, but bats can carry ABLV. This means:

  • Travellers to rabies-endemic countries should take precautions and consider vaccination.

  • Australians should avoid handling bats. Any bite, scratch, or mucous membrane exposure requires urgent medical assessment.

Public Health and Reporting

  • All potential rabies or ABLV exposures should be reported to your state or territory public health authority.

  • Authorities can help assess risk, arrange bat testing (if possible), and guide post-exposure management.

  • Vaccination for some high-risk groups is funded by states and territories.

Key Takeaways

  • Rabies is fatal but preventable with timely wound care and vaccination.

  • Avoid contact with bats and unknown animals overseas.

  • Pre-exposure vaccine is advised for bat handlers, certain travellers, and lab workers.

  • Post-exposure treatment (wound cleaning, vaccine, HRIG if required) must begin as soon as possible.
