Clinical Utility
Exposure to cytomegalovirus (CMV) occurs throughout life and by adulthood, 50-90% of the population is seropositive for CMV antibodies. CMV is spread by close contact, sexual transmission, perinatal or congenital transmission, and through blood transfusions and tissue transplants. Intrauterine or congenital infections occur in 0.5 to 2.2% of all live births. Symptomatic congenital infections usually occur in infants born to non-immune mothers who have primary infections during pregnancy.
