An in-depth guide to symptoms and ways to avoid catching the flu this winter.


Influenza (flu) is a highly contagious respiratory illness caused by influenza viruses.

It is spread by body fluids from infected people.

The flu spreads:

  • when an infected person coughs or sneezes, and you breathe it in
  • through direct contact with fluid from an infected person’s coughs or sneezes
  • by touching a contaminated surface with the flu virus on it, and then touching your mouth, eyes or nose


Flu is more serious than a common cold

The flu can lead to:

  • bronchitis
  • croup
  • pneumonia
  • ear infections
  • heart and other organ damage
  • brain inflammation and brain damage
  • death


In Australia in 2019 there were:


The COVID-19 pandemic has led to decreased exposure to the influenza virus and lower influenza vaccine coverage compared to previous years. But with an end to lockdowns and state and international borders reopening, doctors are expecting a resurgence of influenza in 2022, prompting warnings of a potentially monster flu season ahead.

Symptoms of flu

Flu symptoms may last for at least a week and can include:

  • fever
  • cough
  • sore throat
  • runny or stuffy nose
  • muscle aches
  • joint pains
  • headaches
  • fatigue
  • nausea
  • vomiting and diarrhoea (more common in children than adults)

The symptoms of COVID-19 and flu can be similar. If you have any cold or flu-like symptoms, you should take a test for COVID-19 straight away, even if you are up-to-date with your vaccinations.

If you have flu-like symptoms but have tested negative to COVID-19, you should still stay home until your symptoms clear up to prevent the spread of illness.



What do I do if I get the flu?

  • Rest
  • Drink plenty of fluids
  • Consider taking gentle pain relief for muscle aches and pains

Children under 16 who are ill with flu should not be given medication containing aspirin. Contact your GP if you’re concerned about you or your child’s illness.

Flu complication risks

Some groups may be at risk for serious complications from flu, and your GP may want to prescribe antiviral medication.

These groups include:

  • children from six months to under five years of age
  • people with serious health conditions (including severe asthma, diabetes, cancer, immune disorders, obesity, kidney, heart, lung or liver disease)
  • pregnant women
  • Aboriginal and Torres Strait Islander people from six months of age
  • people who are 65 years of age and over

If your symptoms become severe (difficulty breathing, sudden dizziness or confusion, pain or pressure in the chest) call Triple Zero (000) straight away.



Your GP should be the first port of call when you’re sick 

Save hospital emergency departments for emergencies, especially during this busy winter flu season.

If you have a fever or flu-like symptoms, like a cough or runny nose or are short of breath, please ring your GP clinic’s reception prior to your appointment to discuss your appointment options.
