Clinical Significance
Primary infection by EBV causes infectious mononucleosis, usually a self-limiting disease in children and young adults. Infection with EBV can cause lymphoproliferative disorders including tumors. VCA-IgM is typically detectable at clinical presentation, then declines to undetectable levels within a month in young children and within 3 months in other individuals.
