RESUMEN
A transversal survey on 150 pregnant women was carried out at the P.M.I. center in Yopougon, in order to determine the prevalence of genital herpes and to estimate the frequency of asymptomatic excreting of Herpes simplex virus (HSV) in pregnant women. The viral isolation and the direct immuno-fluorescence (IF) assay of the genital secretions were found to have a prevalence of 12.7% Among the women who tested positive (the majority of whom were from modest socio-economic origin and young), 10% had antecedents of genital herpes, 2.7% showed an asymptomatic excretion and 36.8% had an acute episode during their pregnancy including a primary infection in the 20th week. In these women an unexpected recurrence will constitute the major risk for maternal transmission and an emergence of neonatal herpes.
