BACKGROUND: Cytomegalovirus (CMV) is the most common cause of congenital infection, with increased morbidity and mortality at birth. The risk of intrauterine infection largely depends on the time of maternal infection during pregnancy. Currently, no national screening test for CMV infection is available during pregnancy in Iran. The aim of this study was to determine the seroprevalence of CMV infection in pregnant women in the east region of Iran. METHODS: In this descriptive study, conducted from February to April 2011, 240 serum samples were collected from pregnant women in the third trimester to measure CMV-specific immunoglobulin G (CMV-IgG) and CMV-specific immunoglobulin M (CMV-IgM) markers using ELISA test. IgG avidity test was used for all patients whom were positive CMV-IgM and positive CMV-IgG to distinguish primary and recurrent CMV infection. All positive CMV-IgM of pregnant women were monitored until birth. RESULTS: The majority of women (72.1%) were positive CMV-IgG in pregnancy. The rate of positive CMV-IgM, primary and recurrent infection was 2.5%, 0.83%, and 1.67% respectively. There was significant relation between history of abortion (P = 0.013) and residential place (P = 0.017) with IgG seropositive rate. Two subjects with positive CMV-IgM were faced with preterm labor and low birth weight. CONCLUSION: The findings of our study indicated high prevalence rate of CMV seropositivity in this part of eastern region of Iran. A national screening of CMV-IgM serological is suggested for pregnant women who are at risk of CMV infection.
