Influenza (Flu): What You Need to Know

Influenza (commonly known as the flu) is a highly contagious viral infection that affects the respiratory system, including the nose, throat, and lungs. While many people recover within a week, influenza can sometimes lead to serious complications—especially in vulnerable groups.
What Are the Symptoms of Influenza?
Flu symptoms often come on suddenly and may include:
Fever and chills
Cough and sore throat
Runny or blocked nose
Muscle aches and fatigue
Headache
Occasionally nausea, vomiting, or diarrhoea (more common in children)
Why Can Influenza Be Serious?
For some individuals, influenza is more than just a “bad cold.” It can lead to severe complications such as:
Pneumonia (infection of the lungs)
Worsening of chronic conditions (e.g. asthma, diabetes, heart disease)
Hospitalisation
Dehydration, especially in children and elderly patients
Rare but serious complications, including:
Inflammation of the heart (myocarditis)
Brain inflammation (encephalitis)
Severe respiratory failure
In high-risk groups—including people over 65, young children, pregnant women, and those with chronic medical conditions—the flu can be life-threatening.
How Does the Influenza Vaccine Help?
The influenza vaccine is the most effective way to reduce your risk of catching the flu and developing severe illness.
Benefits of the Flu Vaccine:
Reduces the risk of getting influenza
Decreases severity if you do get infected
Helps prevent hospitalisation
Protects vulnerable members of the community
Reduces spread within families and workplaces
Because the influenza virus changes each year, annual vaccination is recommended.
Are There Any Side Effects of the Flu Vaccine?
The flu vaccine is generally very safe and well tolerated.
Common (Mild) Side Effects:
Pain, redness, or swelling at the injection site
Mild fever
Fatigue or muscle aches
Headache
These usually resolve within 1–2 days.
Less Common Side Effects:
Mild allergic reactions (e.g. rash)
Rare but Serious Side Effects:
Severe allergic reaction (anaphylaxis) – extremely rare and treatable
Guillain-Barré Syndrome (very rare neurological condition)
Your doctor or nurse will assess your suitability before vaccination.
Who Should Get Vaccinated?
Annual influenza vaccination is recommended for everyone aged 6 months and older, particularly:
Adults aged 65 years and over
Children under 5 years
Pregnant women
Aboriginal and Torres Strait Islander people
Individuals with chronic medical conditions
In Western Australia, some groups are eligible for free influenza vaccination under the National Immunisation Program.
When Should You Get Vaccinated?
The best time to get vaccinated is before the flu season starts (usually April to June in WA), but vaccination at any time during the season can still provide protection.
When Should You See a Doctor?
Seek medical attention if you or your child experience:
Difficulty breathing
Chest pain
Persistent high fever
Confusion or drowsiness
Symptoms worsening or not improving after a few days
