What you need to know about flu (influenza)

As flu season approaches, it’s important for our school community to understand what the

flu is, how it spreads, and how to keep families healthy and safe.

What is the flu?

The flu, short for influenza, is a highly contagious viral infection that affects the 

respiratory system (nose, throat, and lungs). Unlike the common cold, the flu can cause sudden, more intense symptoms and, in some cases, lead to serious complications like pneumonia, especially in young children, the elderly, and people with existing health conditions.

How does the flu spread?

The flu virus spreads easily through coughs, sneezes, and touching contaminated 

surfaces. It can live on surfaces like door handles and desks for up to 48 hours.

Common flu symptoms

If your child has the flu, they may suddenly develop:

• High fever (38°C or more)

• Dry cough and sore throat

• Runny or stuffy nose

• Headache and body aches

• Extreme tiredness or lethargy

• Sometimes nausea, vomiting or diarrhoea.

Flu symptoms often appear quickly and can last from a few days to over a week.

Caring for the flu at home

Most children with the flu recover at home with:

• Plenty of rest

• Lots of fluids

• Paracetamol or ibuprofen for fever and aches (avoid aspirin in children).

Antibiotics don’t work against viruses like the flu, but a doctor may prescribe antiviral medication such as Tamiflu in certain cases.

When to seek medical help

See a doctor if your child:

• Has trouble breathing

• Is not drinking fluids or is dehydrated

• Is very drowsy or irritable

• Has flu symptoms that improve and then suddenly worsen again.

Call 000 (Emergency) if your child:

• Is struggling to breathe

• Has blue or grey skin

• Won’t wake up or respond.

Flu vs COVID-19

Flu and COVID-19 share many symptoms. If your child has flu-like symptoms, check with your GP about testing for COVID-19 as well.

Flu prevention: protect your family

Here’s how we can all help reduce the spread of the flu:

• Get vaccinated every year – especially children, elderly, pregnant women, and anyone with chronic health issues

• Cough or sneeze into your elbow

• Wash hands frequently with soap and water or hand sanitiser

• Stay home if you’re sick – even if symptoms seem mild.

Let’s work together to keep our school and families healthy this flu season. If you have questions about flu vaccines or symptoms, talk to your GP or a healthcare provider.
