Child with a high temperature (fever)

Child with a high temperature (fever)

A high temperature (fever) is very common in young children. The temperature usually returns to normal within 3 to 4 days.

How should I check temperature?

Normal body temperature is around 37 degrees celsius. A fever is a raised temperature of 38 degrees Celsius or higher. It is best measured using a digital thermometer if possible.

If your child has a temperature they may:

  • Feel hotter than normal when you touch their chest or back
  • Feel sweaty
  • Look or feel unwell

What causes a temperature?

A temperature is the body’s natural response to fighting infections. Infections caused by viruses are more common than bacterial infections. There are many causes for a raised temperature including common childhood illnesses and vaccinations. 

What should I do at home?

Do:

  • ensure your child drinks plenty; for example water or juice - if you are breast feeding continue to offer frequent feeds
  • offer food if they are hungry; do not worry if your child will not eat
  • give Paracetamol if your child is distressed.  Give the Paracetamol dose according to the instructions on the bottle.  Repeat the dose every 4 hours (up to a maximum of 4 doses in 24 hours) until your child returns to normal. You could also use Ibuprofen if your child is still distressed.
  • check your child in the night
  • keep your child off school or nursery whilst they have a high temperature
  • seek medical advice if you are worried

Do not:

  • do not lukewarm sponge your child
  • do not over or under dress your child
  • do not give paracetamol to children under 2 months old
  • do not give ibuprofen to children under 3 months old or less than 5kg in weight
  • do not give aspirin to children under 16 years old

If your child has any of the following, you should call 999 or return immediately to the Emergency Department:

  • becoming difficult to rouse or is floppy

  • has cold hands and feet and looks mottled (spotted) 
  • starts having a fit or convulsion
  • develops a rash that doesn’t go away when a glass is pressed onto it (a non-blanching rash)
  • is under 3 months with a temperature of 38oC or higher (unless 48 hours post vaccinations with no other worrying features)
