CMV infections are very common and are usually asymptomatic. However, in immunocompromised patients, including organ recipients and AIDS patients, CMV infections may be severe and life-threatening. CMV is the most frequent cause of congenital viral infections in humans and occurs in approximately 1% of newborns. Approximately 90% have no clinical symptoms at birth. Ten to 20% of these infants will develop complications before school age. Congenital infection may occur as a result of either primary or recurrent maternal infection.
