Mother-to-Child Transmission of Cytomegalovirus and Prevention of Congenital Infection.

ABSTRACT: Mother-to-child transmission (MTCT) of cytomegalovirus (CMV) occurs transplacentally (congenital infection), during birth and through breast milk, although the latter 2 modes of transmission are not associated with the central nervous system sequelae that occur with congenital infection. CMV persists indefinitely in its human host, and MTCT can occur if the mother was infected in the past or during the current pregnancy. The goal of efforts to prevent MTCT of CMV is to prevent congenital infection, an important cause of disability due to hearing loss, impaired vision, cognitive impairment, and neuromotor deficits. Vaccines for prevention of maternal and congenital CMV infection are being developed but will not likely be available for at least a decade. Rather than waiting for an effective vaccine to solve the problem, more effort must be devoted to defining the potential for public health measures to prevent congenital CMV infection by reducing rates of maternal infection during pregnancy.
