Description

Infectious mononucleosis (commonly called "mono") is a viral illness most often caused by the Epstein-Barr virus (EBV). It spreads primarily through saliva, which is why it's often nicknamed the "kissing disease."

Symptoms of Mono May Include:

  • Extreme fatigue (often the first and most severe symptom, may lead to sleeping 12–16 hours a day)
  • Fever
  • Headache
  • Muscle aches
  • Sore throat (often severe and similar to strep)
  • Swollen lymph nodes, especially in the neck
  • Loss of appetite
  • Nausea
  • Joint aches
  • Rash, sometimes with tiny red spots in the mouth

Symptoms typically appear 4 to 6 weeks after exposure.

Test Included

Mononucleosis Spot Test (Monospot or Heterophile Antibody Test)

  • A rapid blood test that detects heterophile antibodies produced in response to EBV infection.
  • Helps diagnose acute infectious mononucleosis.
