Clinical Disease

Epstein-Barr virus (EBV) is the etiological agent of infectious mononucleosis and has been implicated in African Burkitt's lymphoma and nasopharyngeal carcinoma. Childhood infections may be asymptomatic or produce "flu-like" illness. Adolescents and adults who escape infection during childhood experience infectious mononucleosis (IM). IM is characterized by irregular fever, pharyngitis, and lymphadenopathy lasting 1 to 4 weeks. Hematological abnormalities include an absolute increase in lymphocytes and monocytes exceeding 50% and more than 15% atypical lymphocytes, lasting for at least 2 weeks. Liver function tests generally reveal a mild to moderate increase in SPGT, SGOT, bilirubin, and LDH levels. IM is usually a benign and self-limited disease. Complications including splenomegaly and splenic rupture, hepatitis, pericarditis, myocarditis, or central nervous system involvement (Guillain-Barre syndrome, Bell's palsy, transverse myelitis, and meningoencephalitis) may occur following IM infection.

Epidemiology

EBV occurs throughout the world and more than 90% of adults have antibodies to the virus. Most individuals acquire EBV early in life. Seroepidemiologic studies have indicated that 50% of children have antibodies to the virus by the time they are 5 years of age. No seasonality has been demonstrated. (1)

Incubation Period

The incubation period is 4-7 weeks. (1)

Transmission

EBV is poorly contagious. Transmission is via salivary contact, either through kissing or by exposure to contaminated eating implements. (1)
