Objective: To determine rubella seroprevalence inwomenwith bad obstetric history (BOH). Patients andmethods:Acase control studywas conducted in Kirkuk, Iraq, which included 538 women with age range from 15 to 48 years. Astructured questionnaires were used to gather sociodemographic data and ELISA was used to detect rubella infection using IgG and IgM kits.Results:Out of the 538women, 435 (80.9%) and 18 (3.3%)were rubella IgG and IgM positive respectively. Women age, occupation, education and family size were significantly associated with serpositive rubella IgG. Women with BOH were with high rubella IgG seropositivity than that in women with normal pregnancy. Current infection was higher in women with normal pregnancy outcomes as compared to that with BOH. Conclusion: This study provides important and highly useful information on baseline seroprevalence data on rubella in Iraq.A19.1%of our women study populationwere non rubella immune and were susceptible for rubella infection. In addition, rubella seroprevalence associated with BOH.
