Sexually transmitted infections during pregnancy.

Two million of the 15 million (13.3%) new cases of sexually transmitted infections (STIs) among persons 15 to 49 years old occur in pregnant women. Access to care and a provider's ability to assess risk, screen, and treat STIs are critical factors in preventing adverse pregnancy outcomes. Significant variations in provider STI screening and treatment practices exist despite recommended guidelines. This article reviews issues related to screening and management of common STIs during pregnancy, with emphasis on the new 2006 US Centers for Disease Control and Prevention Sexually Transmitted Diseases Treatment Guidelines and recently revised recommendations for HIV testing of pregnant women in healthcare settings.
