Seroprevalence of the human immunodeficiency virus (HIV) among pregnant women in eastern Sudan.

We conducted a cross-sectional survey to determine the prevalence of the human immunodeficiency virus (HIV) among pregnant women attending a major hospital in Kassala state, eastern Sudan. Unlinked anonymous testing of residual blood specimens, which were originally collected for other routine clinical purposes, was performed using rapid immunochromatographic assays. In total, 430 residual blood specimens were consecutively collected over a 6-week period (April-May 2010).
