Influenza (flu) is a contagious respiratory illness caused by influenza viruses. It can cause mild to severe illness. Serious outcomes of flu infection can result in hospitalisation or death. Some people, such as older people, young children, and people with certain health conditions, are at high risk of serious flu complications.

The best way to prevent flu is by getting vaccinated each year.

The pages listed below offer public health and health care professionals key information about vaccination, surveillance reports, infection control information, prevention, treatment, and diagnosis of seasonal influenza.

We also provide a range of resources to promote flu prevention within your organisation and communities. Whether you are a health department, hospital, school, community leader, parent, or just interested in communicating important flu information, we have the resources you need.
