Flu Season Ready: Why Prevention is the Ultimate Wellness Habit
What is influenza? (The Flu)
Influenza (the flu), is a highly contagious viral infection that affects the nose, throat and sometimes the lungs. It’s not just a heavy cold. The flu can hit suddenly with fever, chills, cough, sore throat, muscle aches, headache and overwhelming fatigue. Kids may also experience nausea or tummy upset.
The virus spreads through coughs, sneezes, or touching contaminated surfaces. People are often infectious before they feel sick which explains why it sweeps through families, classrooms and workplaces with Olympic-level efficiency.
In Australia, influenza is one of the most common vaccine-preventable illnesses, returning each year with different circulating strains.
How Does Influenza Impact Health?
For most people, the flu causes unpleasant but self-limiting symptoms, think high temperature, drippy nose, sore throat, cough and that “why did I get out of bed?” fatigue.
But sometimes the flu isn’t just annoying, it can be dangerous especially in at-risk people.
Possible complications include:
- pneumonia (infection of the lungs)
- acute bronchitis or worsening of asthma and COPD
- middle ear infections and sinusitis
- heart or muscle inflammation in rare cases
- hospitalisation, and even death in severe cases
Even in healthy adults, the flu can knock you off your feet for a week or more and during that time you can spread it to others. One minute you think it’s “just a flu”, the next you’re deep into a Netflix marathon with a box of tissues with a side of grumpiness.
Certain medical conditions can get worse with the flu, and complications like pneumonia can be life-threatening, especially for people whose immune systems are already under pressure.
Who’s at Higher Risk?
Influenza doesn’t discriminate; anyone can catch it. But some groups are more likely to become sicker than others:
- babies and young children
- older adults (65 years and over)
- pregnant women and newborns
- Aboriginal and Torres Strait Islander peoples
- people with chronic health conditions (heart, lung, immune and metabolic conditions)
- people with weakened immune systems
- people who smoke
How Can You Protect Yourself?
Yearly vaccination is the best defence.
The flu vaccine is the single most effective way to reduce your risk of getting seriously ill from influenza. All people aged 6 months and over are recommended to get vaccinated each year.
Because flu viruses change from year to year, the vaccine is updated annually to match the most common circulating strains. Getting your shot before the season starts (typically April onwards in Australia) gives your body time to build protection.
The flu vaccine can’t give you the flu -it doesn’t contain live virus – but it does help your immune system recognise and fight the real thing.
In Australia, some people are eligible for free influenza vaccination under the National Immunisation Program (NIP) or state-based programs.
These groups typically include:
- children aged 6 months to under 5 years
- Aboriginal and Torres Strait Islander people aged 6 months and over
- pregnant people at any stage
- adults aged 65 years and over
- people with certain underlying medical conditions
Pro tip: immunity from the vaccine is strongest in the first 3–4 months after vaccination, so getting vaccinated early in the season helps.
You can speak to our friendly WholeLife Pharmacy & Healthfoods pharmacists or your GP about your vaccination options.
Everyday Prevention and Symptom Relief
Vaccination is vital, but it works best alongside everyday habits that reduce transmission, such as:
- sanitising or washing hands often
- covering coughs and sneezes
- staying home when unwell
- avoiding close contact with sick people
Masks may be useful in crowded settings, especially if you’re at higher risk or feeling unwell.
If you’re unlucky enough to come down with the flu, there are a few over-the-counter options that can help you (and your family) feel at least semi-human again. Paracetamol or ibuprofen can ease fever and body aches, cold and flu tablets may help with congestion, and some people use vitamin C or zinc for general immune support. For kids, age-appropriate paracetamol is usually the go-to. If you’re unsure what’s best for your household, come in stores and have a chat to one of our friendly WholeLife Pharmacy & Healthfoods team members.
Influenza might be familiar, but it’s no joke. It can make you very sick and spread quickly through families and workplaces. The good news? Annual vaccination plus simple hygiene habits go a long way toward keeping you, and your community, healthier this flu season.
If you’re thinking about your health and how best to protect yourself or someone you care about, our friendly and knowledgeable WholeLife Pharmacy & Healthfoods pharmacists or your GP are great people to talk to about flu vaccination and seasonal protection.
