Primary Infection and Infectious Mononucleosis

Infection with EBV is widespread and the prevalence of the virus in Western populations is more than 90%. The virus primarily spreads via the oral route (saliva) and at a time, approximately half of the asymptomatic virus carriers shed EBV. In nonindustrialized nations, primary infection takes place between 2 and 5 years of age and is mostly asymptomatic. However, infection later in life increases the risk to develop infectious mononucleosis (IM), which is a transient and self-limiting lymphoproli-ferative disease characterized by lymphadenopathy, highgrade fever, hepatosplenomegaly, and pharyngitis or tonsillitis.[3] Atypical mononuclear cells and an inverted ratio of CD4+ vs. CD8+ cells are hematological markers of IM. Generally, IM lasts for 4 to 6 weeks, eventually establishing an asymptomatic persistent infection.
