Diseases

Find information about infectious diseases for everyone and for health professionals.

We regularly add new topics and diseases to this website. In the meantime, additional information remains on the Department of Health, Disability and Ageing website

For everyone

Australian bat lyssavirus

Australian bat lyssavirus (ABLV) causes a rare but serious disease in humans. Anyone bitten or scratched by a bat in Australia should seek urgent medical attention. We monitor and report on human ABLV cases in our community.

COVID-19

COVID-19 is a highly contagious respiratory disease. It spreads through respiratory droplets and airborne particles. It can be serious, especially for certain groups. Getting vaccinated is the best protection. We monitor and report on national data and provide guidelines to minimise the risk.

Hepatitis A

Hepatitis A is a viral infection of the liver. You can get infected by ingesting food or water contaminated with faeces or contact with an infected person. It can be serious, especially for high-risk groups. Vaccination and good hygiene can protect you. We monitor and report on national case data.

Japanese encephalitis virus (JEV) infection

Japanese encephalitis virus (JEV) spreads to humans and other animals through infected mosquitoes. Most people don’t get any symptoms. For the small number who do, it can cause severe illness or even death. The best protection is to avoid getting bitten by mosquitoes and getting vaccinated.

Measles

Measles is a highly contagious viral illness. It can be very serious and cause hospitalisation or death. Getting vaccinated is the best protection. We monitor and report on measles in our community, including national case numbers and trends. We provide guidelines to minimise the risk of spread.

Mpox

Mpox is an infectious disease caused by the monkeypox virus (MPXV). It spreads through contact with infected people or animals, but you can take steps to protect yourself. We monitor and report on case numbers and trends and provide guidelines to minimise the risk.

Respiratory syncytial virus (RSV)

Respiratory syncytial virus (RSV) is a highly contagious respiratory virus. RSV often spreads through respiratory droplets. It can be serious, especially for high-risk groups. Getting vaccinated is the best protection. We monitor and report on RSV in our community, including national case numbers.

Seasonal flu (seasonal influenza)

Seasonal flu most often spreads through respiratory droplets. It can be serious, especially for high-risk groups. Getting vaccinated is the best protection. We monitor and report on flu in our community, including national case numbers. We provide guidelines to minimise the risk.

Syphilis

Syphilis is a sexually transmissible infection (STI) caused by bacteria. It can go undetected, so regular testing is important. It’s easy to cure if found early, but can be serious if untreated. We monitor and report on syphilis case numbers and trends and provide guidelines to minimise the risk.

Whooping cough (pertussis)

Whooping cough (pertussis) is a highly contagious respiratory disease. It spreads through respiratory droplets and can be serious, especially for babies. Getting vaccinated is the best protection. We monitor and report on pertussis in our community, including national case numbers and trends.

For health professionals

Australian bat lyssavirus

Australian bat lyssavirus (ABLV) causes a fatal encephalitis similar to rabies. It is a nationally notifiable disease. We monitor and report on national case numbers. We publish case definitions and guidelines to support health professionals and health authorities.

COVID-19

COVID-19 is a highly infectious respiratory infection caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). It is a nationally notifiable disease. We monitor and report on COVID-19 data and epidemiological trends. We publish case definitions and national guidelines.

Hepatitis A

Hepatitis A is a vaccine-preventable viral infection of the liver. It is a nationally notifiable disease. We monitor and report on national case numbers and epidemiological trends. We publish case definitions and national guidelines to support health professionals and health authorities.

Japanese encephalitis virus (JEV) infection

Japanese encephalitis virus (JEV) spreads to humans and other animals through infected mosquitoes. It is a nationally notifiable disease. We support a One Health approach to JEV and report on national case numbers and epidemiological trends. We publish case definitions, guidelines and advice.

Measles

Measles is a serious viral illness. It is a nationally notifiable disease. We monitor and report on national case numbers and epidemiological trends. We publish case definitions and national guidelines to support health professionals and health authorities respond to measles cases.

Mpox

Mpox is caused by monkeypox virus (MPXV). It is a nationally notifiable disease. We monitor and report on national case numbers and epidemiological trends. We publish case definitions and national guidelines to support health professionals and health authorities.

Respiratory syncytial virus (RSV)

Respiratory syncytial virus (RSV) infection is caused by RSV. It is a nationally notifiable disease. We monitor and report on national case numbers and epidemiological trends. We publish case definitions and national guidance to support health professionals and health authorities.

Seasonal influenza

Seasonal influenza is mainly caused by influenza A or B viruses. It is a nationally notifiable respiratory disease. We monitor and report on national case numbers and epidemiological trends. We publish case definitions and national guidelines to support health professionals and health authorities.

Syphilis

Syphilis is a bacterial sexually transmissible infection (STI). It can be serious if untreated. It is a nationally notifiable disease. We monitor and report on national case numbers and epidemiological trends. We publish case definitions and national guidelines to support health professionals.

Whooping cough (pertussis)

Pertussis is a highly contagious bacterial respiratory disease. It is a nationally notifiable disease. We monitor and report on national case numbers and epidemiological trends. We publish case definitions and national guidelines to support health professionals.
