Infectious mononucleosis (IM) is a potentially serious, but commonly self-limited disease caused by the Epstein-Barr virus. IM is most commonly spread through contact with respiratory secretions, such as saliva or mucus. IM can also be spread through close contact with an infected person, such as through kissing or sharing food or drinks.
Most people are infected with EBV at some point in their lives, but only a small percentage of people develop IM. Symptoms usually develop 4-6 weeks after exposure to the virus and can include fever, fatigue, sore throat, and swollen lymph nodes. IM can also cause rash, chest pain, and diarrhea.
Lab Diagnosis: Atypical lymphocytes, EBV Specific and Heterophile Abs
There is no specific treatment for IM, but symptoms can be treated with over-the-counter medications. Most people recover within a few weeks, but some may experience lasting fatigue or other complications.
