What is the flu?
Influenza, usually called 'the flu', is an infection caused by the influenza virus. It affects the nose, throat, lungs and other parts of the body. It infects many people every year, mostly during the winter months in Aotearoa New Zealand. The flu can be a serious and sometimes life-threatening infection.
What are the signs and symptoms of the flu?
Flu in tamariki 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
- headache
- dry cough which may become moist
- sore throat
- low energy or fatigue
- chills or shivering
- runny or stuffy nose
- upset tummy, vomiting or diarrhoea
- a rash
Sometimes people confuse a cold with the flu. But with the flu, people are usually more unwell and flu symptoms may last longer.
Occasionally, flu can cause serious illness. The flu can be more serious in tamariki who also have a long-lasting (chronic) disease.
How easy is it to catch the flu?
The flu virus is very easy to catch and can affect anyone.
It can spread easily by coughing, sneezing and touching infected surfaces.
Can I do anything to prevent my child catching the flu?

Other things you can do
You can reduce the risk of catching the flu by washing hands, covering coughs and sneezes, cleaning surfaces and staying away from others who are sick.
Wash hands
Make sure everyone in your whānau washes their hands often and thoroughly, including 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
Remind your child to cough or sneeze into their elbow or cover their mouth and nose with tissues. Throw any tissues away as soon as possible. Remind your child to sanitise or wash their hands regularly.
See the KidsHealth page on teaching children to blow their nose for some tips
Clean surfaces
Regularly clean surfaces in the bathroom and the kitchen.
Stay away from people who are sick
Keep away from people who are sick.
If your child becomes sick, keep them at home until they're better.
What is the treatment for the flu?
Most tamariki 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.
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.
Never give your child or young person aspirin as this may increase the risk of Reye syndrome, which is a rare and serious illness.
Give your child regular fluids.
Use saline drops to treat a stuffy nose - ask your pharmacist or health professional 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 health professional?
See a health professional if you think your child has the flu and:
- is less than 12 months old
- was born prematurely and is less than 2 years old
- has been in hospital within the last 3 months
- a long-lasting medical condition
When should I see a health professional urgently?
You should see a health professional urgently if you're worried or your child:
- is taking less than half of their normal feeds
- has fewer than 4 wet nappies in 24 hours
- is severely irritable and is not wanting to be held
- has trouble breathing, has noisy breathing or is breathing fast
- looks unwell
- has tummy pain, vomiting or diarrhoea and seems sicker than you would expect
- doesn't seem to be improving
