Understanding and Preventing the Flu
Flu viruses change from year to year — and sometimes, completely new strains emerge, leading to global pandemics.
In Australia, the official flu season runs from May to September. While anyone can catch the flu, it doesn’t mean you’ll get it every year. People in good health are better equipped to fight off infections. Eating a balanced diet, exercising regularly, and getting enough sleep all help your immune system defend against invading viruses.
How the Flu Spreads
The flu is a viral infection passed from person to person through tiny droplets released when someone coughs or sneezes. These droplets can be inhaled directly or picked up from contaminated surfaces and then transferred to your nose, mouth, or eyes.
Recognising Flu Symptoms
Flu symptoms develop quickly and are generally more severe than the common cold. They may include:
-
Fever of 38°C or higher
-
At least one respiratory symptom: cough, sore throat, or runny nose
-
At least one systemic symptom: headache, muscle aches, sweats or chills, or fatigue
With the flu, it’s common to feel so unwell that even getting out of bed can feel impossible.
Who’s Most at Risk?
Certain groups are at higher risk of developing serious complications such as pneumonia. According to the Ministry of Health, those eligible for a free flu vaccine include people who:
-
Are pregnant
-
Are significantly overweight
-
Use asthma preventers
-
Have diabetes
-
Are aged 65 years or older
-

If You Catch the Flu
If you do get the flu, help stop it from spreading by:
-
Resting at home and avoiding work or school
-
Covering your mouth and nose when coughing or sneezing
-
Washing your hands regularly and drying them thoroughly
-
Avoiding crowded places

Exercising regularly
