The medical community and general public are be-coming increasingly aware of cytomegalovirus (CMV) and cytomegalic inclusion disease (CID) of newborns. This awareness has led to requests for in-formation about the risks of infection and disease due to CMV and suggestions to prevent or limit their spread, particularly in settings where women of childbearing age may be affected. CMV is an ubiquitous virus that infects most persons at some time during their lives. The modes of transmission of CMV from person to person are incompletely un-derstood. Acquisition appears to require close or intimate contact with persons who are excreting CMV in their urine, saliva, or other secretions. The frequency with which sexual contact may cause transmission of CMV is not clear, but venereal transmis-sion appears to be a major source of infection in some adult populations (ie, homosexual men). Infants and children acquire CMV infection either from other infected children or from their mothers either in utero, at birth, or during the perinatal period [1-3]. CMV can also be transmitted via blood transfusions, breastmilk, and transplanted organs [4-7]. Infection in normal children and adults is usually asymptomatic, although in immunocompromised hosts CMV may be an opportunistic pathogen and cause serious illness with high morbidity and mortality. Intrauterine infection with CMV is the most common of all the intrauterine infections and occurs in an estimated 0.4%-2.3% of all live births. It can have a variable outcome and may result from either primary infection acquired during gestation or a recurrent maternal infection (reactivation or reinfection) in a seropositive woman [8]. It is currently believed that most, but not all, symptomatic congenital CMV infections result from primary in-fection.In the United States, 10%-65% of women (de-pending on their race and socioeconomic status) entering their childbearing years are seronegative and susceptible to primary CMV infection [8]. The rate of seroconversion during pregnancy is estimated to be between 1% and 2% 0 [9-11]. Only 40%-50% of pregnant women who develop primary CMV infec-tion will transmit that infection to their fetuses. Of those infants infected, one study [9] has found that 5%-10% will show symptoms at birth. The most se-verely affected are those with CID manifested by hepatosplenomegaly, jaundice, petechial rash, chorioretinitis, cerebral calcifications, and microcephaly. These children with CID are the major long-term public health problem associated with CMV. Of con-genitally infected infants, 90%-95% are sympto-matic at birth: 10% of these will develop manifestations of infection later in childhood, usually hearing loss (which is sometimes progressive) or poor intellec-tual performance [12, 13]. Congenital or perinatal infections are chronic in nature, with viral excretion
