What is the flu?

Influenza, or 'the flu', is a highly contagious respiratory illness. It's a common cause of hospitalisation and leads to thousands more GP visits every year. Many people die annually from complications of the flu in Australia.

While you can catch the flu at any time, it's more likely to happen in the colder months of the year (April to October). The flu season typically peaks in August, but laboratory-confirmed cases of influenza have been higher than usual so far this year — as have calls about flu-related symptoms to the healthdirect helpline.

Early signs of the flu can include cough, sore throat, sinusitis or fever.

What are the best ways to fight the flu?

Follow these easy tips to help prevent the spread of flu:

Get a flu shot

It is important to get the influenza vaccination each year to continue to be protected, since it wears off after 3 to 4 months and flu strains (types) change over time.

Wash your hands

In addition to vaccination, good hygiene is one of the best ways to help prevent flu and other illnesses from spreading. Wash your hands regularly.

Cover coughs and sneezes

Cover your mouth and nose when coughing or sneezing.

Bin your tissues

Throw used tissues in the bin immediately.

Avoid sharing

Don't share cups, plates, cutlery and towels with other people, if you can.

Keep surfaces clean

Clean surfaces such as your keyboard, phone and door handles regularly to get rid of germs.

Self-care at home

In most cases, you can treat mild flu or cold symptoms at home.

NOTE: Antibiotics won't help

Antibiotics do not reduce symptoms of flu or a cold, as these illnesses are caused by viruses. Antibiotics only work for bacterial infections.
