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.
