What Is Fever in Children?

Fever in children is a temporary rise in body temperature, often in response to an infection. It is a common symptom and usually indicates the body is fighting illness.

What Causes Fever in Children?

  • Viral infections (cold, flu, COVID-19)
  • Bacterial infections (ear infections, urinary tract infections)
  • Immunizations (temporary post-vaccine fever)
  • Inflammatory or autoimmune conditions (less common)

What Are the Common Symptoms?

  • Elevated temperature above 38°C (100.4°F)
  • Sweating or chills
  • Irritability or fussiness
  • Loss of appetite
  • Fatigue or lethargy
  • Headache or body aches

How Is Fever in Children Diagnosed?

  • Measurement of temperature using a thermometer
  • Assessment of associated symptoms
  • Online GP consultations can advise on monitoring and symptom management; in-person review may be needed if serious signs are present

How Long Does Fever Last?

  • Most fevers due to viral infections resolve within 2–3 days
  • Fever lasting more than 3–5 days may require further assessment

Is Fever Contagious?

Fever itself is not contagious, but the underlying infection may be.
