HiPP's A-Z of pregnancy & child health

The A-Z contains information on many aspects of pregnancy 
and child health. It is arranged alphabetically so you can find what you are looking for with ease. If you are at all concerned about your health or your child’s health, please consult your health professional.



Fever/High Temperature


The medical term for a fever or high temperature is pyrexia. The normal average body temperature of a child is around 37°C (but this does vary). It?s always distressing when your baby or child has a fever, but it?s seldom harmful. Most fevers are caused by infections - either a bacterial infection such as tonsillitis, or a viral infection such as flu. White blood cells in the body fight infection and raise the temperature of the body in an effort to destroy the bacteria or virus.

Contact your doctor, or NHS Direct (0845 46 47), if you are at all worried - or if your child?s fever lasts more than 3 days.
