Risk factors for HIV in pregnant women.

Worldwide, the number of childbearing women infected with the human immunodeficiency virus (HIV) is rising. Early intervention can improve care for these women and reduce HIV transmission to their children. However, for intervention strategies to be effective, childbearing women at risk must be identified. HIV prevalence and risk factors vary widely from one region to another, and strategies for HIV testing must be tailored to local conditions. In this review, published data on HIV risk factors in pregnant women are presented by region, and implications for regional strategies for HIV testing in pregnant women are discussed.
