What is Fever?

Fever is a body temperature above the usual range and is a sign rather than a diagnosis. Normal temperature varies between people and throughout the day. Interpretation considers the measurement method, age and accompanying symptoms. Infection is common, but medicines, inflammatory conditions and other causes can also raise temperature.

Care depends on the cause and the person's condition; the temperature number alone does not determine illness severity. Infants and people with weakened immunity need early assessment. Fever with breathing difficulty, altered consciousness or a stiff neck requires urgent care.

Possible causes

  • Viral infections such as colds and influenza.
  • Bacterial infections in the throat, urinary tract, or elsewhere.
  • Some inflammatory conditions.
  • Sometimes briefly after vaccinations.
  • Heat stroke in extremely hot weather.

These are common causes; identifying the source of fever may require medical evaluation if needed.

Self-care

Maintain fluids and rest. Do not give aspirin to children or teenagers for fever; ask a clinician or pharmacist about suitable medicine.

When to see a doctor

Consult a doctor if:

  • Fever persists for more than three days or returns after improvement.
  • Temperature is very high or does not decrease with usual care.

Seek emergency care immediately if fever is accompanied by neck stiffness, rapid spreading rash, difficulty breathing, or confusion. For infants and young children, consult a doctor early.
