Diseases of concern in Australia

Some communicable diseases are of concern because of their potential to spread and cause serious illness. We issue health alerts to warn about disease outbreaks of concern within Australia.

Most people will have several communicable diseases in their lifetime, such as the common cold or a stomach bug. These are usually mild and only last for a few days.

However, some diseases can cause serious illness or death. So it’s important that we take steps to prevent, monitor and respond to communicable diseases.

We need to monitor some diseases. This is called communicable disease surveillance.


We report on those diseases via various channels, including the Communicable Diseases Intelligence journal.

The Australian Institute of Health and Welfare publishes a communicable diseases snapshot.
