Pathogenesis of HSV and CMV Infections in Pregnancy.
Human herpesvirus (HHSV) and human cytomegalovirus (HCMV) infections during pregnancy are a major concern of public health because of the risk for severe sequelae for the fetuses and the neonates and because primary infections, reinfections and reactivations can be asymptomatic. The risk for neonatal herpes is mostly congenital, while the risk for HCMV infection is either prenatal or congenital. Screening exposed women has not brought definite solutions but is currently being evaluated. Among pregnant women with active infection, evaluation of the fetus for contamination and thus for the risk for severe immediate or long-term sequelae for neonates is the major goal. Diagnostic tools are available, cell culture still being the gold standard, and polymerase chain reaction (PCR) being currently evaluated for its contribution to diagnosis of active infection. Consensus for screening pregnant women as well as achievement of antiviral vaccines are the most urgent intervention strategies to develop in the near future.
