[Primary cytomegalovirus infection and pregnant women: epidemiological study on 1100 women at Limoges].

During 13 months, 1101 women attending for antenatal care at Limoges University Hospital were prospectively studied to determine the prevalence of Cytomegalovirus (CMV) antibodies: 47.9% of these women were CMV seropositive. Ethnic group was strongly associated with CMV status: 42.6% of metropolitan and 94.5% of immigrant women were seropositive. Seropositivity was associated with increasing parity and older age. The risk of a susceptible woman to acquire CMV infection during pregnancy is 0.7%. Among the 4 seroconversions, 3 children were infected, with developmentally and neurologically normal status in one case, moderate ear damage in an other case and a disseminated infection in the third case requiring a provoked abortion.
