Cytomegalovirus infection in a cohort of pregnant women.

Enzyme linked immunosorbent assay was used to detect the seroprevalence of cytomegalovirus (CMV) immunoglobulin M (IgM) and immunoglobulin G (IgG) in 300 pregnant women. Seventeen (5.7%) and 274 (91.3%) women were seropositive for IgM and IgG, respectively. There was significant increase in seroprevalence of CMV IgG and no significant increase in seroprevalence of CMV IgM among tested age groups. CMV IgM and IgG seroprevalence differed nonsignificantly by type of residence, the stage of pregnancy, and the level of education.
