Fever is one of the most common reasons parents seek medical advice. It is also one of the easiest symptoms to focus on too narrowly. The temperature matters, but so do the child’s age, behaviour, breathing, hydration and the other symptoms happening around it.
What matters besides the temperature?
A child with a moderate fever who is drinking, interacting and breathing comfortably may look very different clinically from a child with the same temperature who is difficult to wake, struggling to breathe or unable to keep fluids down.
When assessing fever, a GP may consider how long it has been present, whether the child is eating and drinking, urine output, breathing effort, rash, pain, vomiting, diarrhoea and whether the child is behaving very differently from usual.
When is a GP appointment useful?
Primary care is useful when fever is persistent, recurring, associated with ear pain, cough, sore throat, rash, vomiting, diarrhoea or another symptom that needs examination. The doctor can examine the ears, throat, chest, abdomen and skin and decide whether testing or treatment is needed.
When should parents seek urgent care?
Urgent assessment is appropriate when a child has severe breathing difficulty, is difficult to wake, has a seizure, shows signs of severe dehydration, has a concerning non-blanching rash, or is deteriorating rapidly. Very young infants also require a lower threshold for medical assessment.
What about antibiotics?
Fever does not automatically mean a bacterial infection. Many childhood fevers are caused by viruses, and antibiotics do not treat viral illness. The decision to prescribe antibiotics should be based on the clinical picture and examination rather than the temperature alone.
If you are unsure, the safest question is not “How high is the fever?” but “How is my child doing overall, and is anything changing for the worse?”
