What should you know about acute fever?

How unwell the person looks and feels matters alongside the temperature reading. Most care focuses on comfort, fluids and watching for warning signs while the underlying cause becomes clearer.

Fever can accompany respiratory, skin and other infections. Chills, sweating, tiredness, muscle aches or reduced appetite may occur with it. The pattern of other symptoms—such as cough, breathing difficulty, rash, painful urination or a tender red area of skin—helps a clinician investigate the cause.

A thermometer gives a more useful reading than judging warmth by touch. Note where and how the temperature was measured because readings can differ by method.

Rest, drink regularly and wear light, comfortable clothing. Offer a child frequent fluids and continue feeding when tolerated. Avoid cold baths or heavy wrapping, which can worsen discomfort or shivering.

If you use a fever medicine, follow the label for the person's age and health, and check that another cold or flu product does not contain the same ingredient. Aspirin is not suitable for children. Record temperatures, symptoms, medicines and fluid intake if the illness continues.

Seek emergency help for severe breathing difficulty, blue or grey lips, confusion, collapse, a seizure, a stiff neck, a rash that does not fade under pressure, or difficulty waking the person. A fever in a very young baby needs prompt medical assessment.

Arrange clinical advice when fever persists, repeatedly returns, follows recent travel, or occurs with dehydration, worsening pain, immune suppression or pregnancy. Get earlier help when a child is not drinking, has fewer wet nappies, is unusually drowsy or is steadily getting worse.

Ask what cause fits the accompanying symptoms, whether an examination or test is needed, which medicines are suitable with your current conditions, and what specific change should trigger reassessment. Mention recent travel, sick contacts, new medicines, vaccination history and any condition that affects immunity.
