Fever in children

For children under 1, see Fever in babies.

A fever is an abnormally high body temperature of 38°C (100°F) or above. It is usually a sign that the body is fighting an infection. Heat exposure can also lead to a raised temperature. A child with a fever will feel generally unwell and be hot and sweaty. If your child does not feel well, you should take his or her temperature (see Taking your child's temperature). If it is raised, take steps to reduce it (see Bringing down a fever). A high fever can cause seizures (febrile convulsions) in young children.

Warning

Danger signs Call an ambulance if your child has a fever that is associated with any of the following symptoms:

  • A seizure lasting more than 5 minutes
  • Flat, dark red spots that do not fade on pressure (see Checking a red rash)
  • Abnormal drowsiness
  • A severe headache

While waiting for medical help, follow the advice for bringing down a fever.

Self-Help Taking your child's temperature

Using an aural thermometer
Hold the thermometer in your child's ear for the recommended time. A new disposable tip should be attached for each use.

A convenient method of taking your child's temperature is with an aural thermometer, which is placed in the ear. You can also use a standard thermometer placed in the armpit or in the mouth. Do not put a glass thermometer in the mouth of a child aged under 7. For the correct result, add 0.6°C (1°F) to a reading from the armpit.

Self-Help Bringing down a fever

Cooling your child
Undress your child, lie him or her in a cool room, and sponge his or her head and body with tepid water.

Lowering a temperature will help your child feel more comfortable and lessens the likelihood of a febrile convulsion occurring. Remove your child's clothes and give him or her plenty of cold drinks. If your child is over 2 months old, give him or her the recommended dose of paracetamol. If the fever doesn't fall and your child is over 6 months old, give him or her the recommended dose of ibuprofen as well. The doses of both drugs can be repeated every 4 hours.
