What is Glandular Fever?

Glandular fever, also known as infectious mononucleosis or 'mono,' is a viral infection primarily caused by the Epstein-Barr virus (EBV). It commonly affects teenagers and young adults, earning it the nickname 'kissing disease' due to its transmission through saliva.

Common Symptoms

  • Severe fatigue and exhaustion
  • High fever (38-40°C/100.4-104°F)
  • Swollen lymph nodes in neck and armpits
  • Sore throat
  • Swollen tonsils with white patches
  • Headache
  • Loss of appetite
  • Muscle aches

Diagnosis

Your doctor may diagnose glandular fever through:

  • Physical examination
  • Blood tests (including monospot test)
  • Full blood count to check white blood cells

Treatment Options

Self-Care Measures

  • Plenty of rest
  • Adequate fluid intake
  • Over-the-counter pain relievers
  • Warm salt water gargles

Medical Management

  • Usually no specific treatment required
  • Symptoms typically resolve within 2-4 weeks
  • Occasionally antibiotics if secondary bacterial infection occurs

Important Precautions

  1. Avoid contact sports for at least 8 weeks
  2. Rest when feeling fatigued
  3. Avoid alcohol while recovering
  4. Protect others by not sharing drinks or utensils

When to Seek Medical Help

Consult your doctor if you experience:

  • Severe abdominal pain
  • Difficulty breathing
  • Extreme weakness
  • Yellowing of skin (jaundice)
  • Severe headaches

Recovery Period

Most people recover within 2-4 weeks, though fatigue may persist for several months. Gradual return to normal activities is recommended.
