High Temperature (Fever) in Children

A high temperature, also known as fever, is a common symptom in children. It is usually a sign that the body is fighting an infection.

Causes of Fever in Children

  • Viral infections such as the common cold, flu, and gastroenteritis
  • Bacterial infections such as pneumonia, urinary tract infections, and meningitis
  • Immunizations, which can cause a low-grade fever in some children
  • Teething, which can cause a mild increase in temperature
  • Other medical conditions such as ear infections, tonsillitis, and appendicitis

Symptoms of Fever in Children

How to Measure a Child's Temperature

  • Digital thermometer: can be used orally, rectally, or under the arm
  • Tympanic thermometer: measures temperature through the ear
  • Temporal artery thermometer: measures temperature through the forehead

Treatment of Fever in Children

  • Offer plenty of fluids to stay hydrated
  • Dress the child in light clothing to help lower their body temperature
  • Use a fan or open a window to keep the room cool
