Serious childhood illnesses: what to do
Babies and young children with the signs and symptoms listed in this article are at risk of serious illnesses.
If you notice any of the problems listed below, seek medical attention as soon as possible. You know your child best, so trust your instincts if your child doesn’t seem well.
When to call an ambulance for childhood illnesses
If you notice any of the following signs and symptoms, call 000 and ask for an ambulance:
- drowsiness or unresponsiveness
- high-pitched weak or continuous crying
- difficulty breathing or unusual breathing
- pale, mottled or blue skin
- fits or seizures
- non-blanching rash – a rash that doesn’t fade when you press your child’s skin.
There’s more information about these signs and symptoms below.
Drowsiness and unresponsiveness
It’s normal for your child to be sleepy sometimes – for example, after a feed. But if your child seems sleepier than usual, this can be a sign of serious childhood illnesses.
If you can’t wake up your child even when you try really hard many times, get help immediately.
Unresponsiveness can be a sign of several serious childhood illnesses and conditions, including low blood sugar (hypoglycaemia) or a life-threatening brain infection (meningitis).
High-pitched, weak or continuous crying
All babies and young children cry. But if your child is crying in an unusual way, the crying doesn’t stop, and you have trouble settling your child, you should be concerned.
Difficulty breathing or unusual breathing
If your child is having difficulty breathing, you might notice that:
- she has to breathe much harder to get air into her lungs
- she has a persistent cough
- the muscles between her ribs pull in when she tries to breathe
- she can’t make any conversation or sounds.
In severe cases, your child might look very tired and blue. He might be quiet or make a grunting noise with each breath.
Pale, mottled or blue skin
Pale, mottled or blue skin might be caused by poor blood circulation or low levels of oxygen in the body, both of which can happen in serious childhood illnesses.
Fits or seizures
If your child is having a fit or seizure, her eyes might roll backwards. She might be unresponsive, shake violently in all limbs for a short time, and even briefly turn blue.
Roll your child onto his side, keeping his top leg bent. This is the recovery position. Don’t put anything (including your fingers) in your child’s mouth during this time. This might block your child’s breathing.
Non-blanching rash (positive glass test)
Skin spots or blotches that don’t fade when you press directly on your child’s skin can be an early sign of life-threatening meningococcal infection.
You can do the ‘glass test’ by pressing the side of a clear glass firmly against the rash on your child’s skin. If the spot or rash doesn’t disappear when you do this, it might be a medical emergency. Call 000 and ask for an ambulance.
When to go to the hospital emergency department for childhood illnesses
If you notice any of the following signs and symptoms take your child straight to the nearest emergency department:
- a temperature above 38°C in babies less than three months old
- poor urine output
- poor feeding
- frequent vomiting.
There is more information about these signs and symptoms below.
High temperature above 38°C
A high temperature is the body’s normal way of fighting infections. Most children with a high temperature don’t have a serious illness. But in some cases, a high temperature can be a sign of serious infection.
If your baby is under three months and develops a high temperature, a doctor needs to see her immediately. This is because it’s harder to tell whether children in this age group have serious underlying illnesses.
But if your child is over three months and doesn’t show other signs of serious illness, you could also take your child to the GP if you can get an appointment on the same day.
Feeling your child’s skin temperature (for example, by putting your hand to his forehead) isn’t always a reliable way of diagnosing a fever. The best way to check your child’s temperature is with a thermometer.
There are several different methods for taking a child’s temperature using a thermometer:
- orally – putting a digital thermometer in your child’s mouth under the tongue
- rectally – putting the thermometer a little way into your baby’s rectum
- axillary – putting the thermometer under your child’s armpit
- aurally – putting a digital ear thermometer into your child’s ear, which can be a little inaccurate
- superficially – wiping a device called a temporal artery thermometer across your child’s forehead.
Poor urine output
An early sign of many serious illnesses is fewer wet nappies than usual – that is, fewer than half the number of wet nappies your child usually has each day. It could mean your child is dehydrated.
If your child isn’t feeding well or has no interest in feeding, this could be an early sign of childhood illness.
Vomiting is a normal way for the body to get rid of something it doesn’t want. But vomiting that doesn’t stop can cause dehydration and dangerous imbalances in the body’s chemical system.
If your child can’t eat or drink anything and is still vomiting after 24 hours (or 12 hours for children under two years), go to the emergency department.
