The flu is not the same as having a bad cold. The flu can be a serious and sometimes life-threatening infection. Yearly flu immunisation offers the best protection.
Key points to remember about the flu
- the flu (influenza) can be a serious and sometimes life-threatening viral infection
- it is not the same as having a bad cold
- flu is very easy to catch so good hygiene is very important to reduce spread
- even if your child is fit and healthy, they can easily catch the flu
- flu immunisation every year offers the best protection
- keep infected children away from other people and don't send your child to day care or school if they are unwell
- contact your doctor if you are concerned about the severity of your child's symptoms, they are under 12 months old, or have a long-lasting (chronic) medical condition
What is the flu?
Influenza, commonly called 'the flu', is an infection caused by the influenza virus. It affects the nose, throat, lungs and other parts of the body. The flu can be a serious and sometimes life-threatening infection. It infects many people every year, mostly during the winter months in New Zealand.
What are the signs and symptoms of the flu?
Flu in children usually causes at least 2 or 3 of the following symptoms:
- a fever that starts suddenly (a temperature more than 38 degrees Celsius)
- body aches or pains
- dry cough which may become moist
- sore throat
- low energy or fatigue
- chills or shivering
- runny or stuffy nose
- upset tummy, vomiting or diarrhoea
Sometimes people confuse a cold with the flu. But with the flu, people are generally more unwell and flu symptoms may last longer.
Occasionally, flu can cause serious illness. This depends on the type of virus and a child's age and general health. The flu can be more serious in children who also have a long-lasting (chronic) disease. Your doctor can give you more advice if your child has one of these conditions.
How easy is it to catch the flu?
The flu virus is very easy to catch and can affect anyone - it doesn't matter how fit and healthy your child is.
It can spread through the air by coughing and sneezing as well as by hands, cups and other objects that have been in contact with an infected person's mouth or nose.
Can I do anything to prevent my child catching the flu?
Flu immunisation offers the best protection. For more information, see Flu immunisation.
You can also reduce the risk of catching the flu by washing hands, covering coughs and sneezes, cleaning surfaces and staying away from others who are sick.
Make sure everyone in your family washes their hands often and thoroughly, including (but not only) before preparing food and eating. Make sure everyone dries them well too. Soap and water for 20 seconds, then 20 seconds drying. Or use a hand sanitiser.
Cover coughs and sneezes
Cough or sneeze into your elbow or cover your mouth and nose with tissues. Put used tissues in the bin or a bag immediately and then wash and dry hands.
Regularly clean surfaces in the bathroom and the kitchen.
Stay away from people who are sick
Keep your distance from people who are sick - at least two metres.
If your child becomes sick, keep them at home and don't send them to school or daycare until they are well.
If you become sick - stay at home, don't go to work.
What is the treatment for the flu?
Most children fight off the infection by themselves.
Antibiotics are not helpful for the flu and your doctor won't prescribe them unless your child also has a bacterial infection.
Never give your child or young person aspirin as this may increase the risk of Reye syndrome, which is a rare and serious illness.
Continue with your child's usual medicines (such as those for asthma, diabetes and epilepsy).
How can I care for my child with the flu at home?
If your child is miserable because of fever or aches and pains, you can give paracetamol to make them more comfortable. You must follow the dosage instructions on the bottle. It is dangerous to give more than the recommended dose.
See Fever on this website.
Give your child regular fluids.
Use saltwater drops (saline) to treat a stuffy nose - ask your pharmacist or family doctor for instructions.
Keep your child at home and resting until they are well.
When should I seek help for my child with the flu?
When do I need to see a doctor?

When should I see a doctor urgently?
You should see a doctor urgently if your child of any age:
- is drinking less than half of their normal breastmilk or other fluid

- is severely irritable and is not wanting to be held
- has trouble breathing, has noisy breathing or is breathing fast
