Brief Summary

Human cytomegalovirus (HCMV) is the leading infectious agent causing congenital disabilities such as mental retardation, psychomotor delay, hearing loss, speech and language disabilities, behavioural disorders and visual impairment. About 0.6% newborns are HCMV-congenitally infected and, among these, about 20% are symptomatic at birth or will develop long-term sequelae. The public health impact of congenital HCMV is substantial although greatly unrecognized. In Italy, estimated direct costs per affected child exceed €100.000 for a total of €60-70M. HCMV is also a significant cause of infection/disease in the immunocompromised host. Epidemiological studies and population-based models have preliminarily documented that most of the burden associated to congenital HCMV would be due to non-primary maternal infection. Presently, reinfections are believed to be responsible for the great majority of infected fetuses born to immune mothers. This study addresses incidence, outcome and prevention of congenital HCMV infection in seropositive pregnant women.The study includes 2 parts: part 1 in which the incidence and outcome of congenital HCMV is investigated in a large population of HCMV seropositive pregnant women and HCMV shedding and immune response is closely monitored in a subset of participants (nested study); part 2 in which the efficacy of an hygiene intervention is assessed.
