Abstract
The cause of bacterial vaginosis remains poorly understood. Recent evidence strengthens the association between bacterial vaginosis and serious medical complications. To review the evidence linking bacterial vaginosis with adverse pregnancy outcomes, complications after gynecologic procedures, and HIV infection, and to identify prevention strategies. In March 1999, the Centers for Disease Control and Prevention organized a conference to accomplish this goal. Better understanding is needed concerning the etiology, epidemiology, and natural history of bacterial vaginosis. More efficacious treatment of bacterial vaginosis and strategies to reduce maternal complications associated with bacterial vaginosis, such as premature rupture of the fetal membranes, chorioamnionitis, premature labor and delivery, postdelivery endometritis, and postpartum infant complications should be developed. Recent evidence shows that screening and treatment of bacterial vaginosis before abortion reduces postabortion pelvic inflammatory disease, and that anaerobic coverage during hysterectomy reduces postoperative complications. Better understanding concerning the relation of bacterial vaginosis to acquisition of sexually transmitted diseases and HIV infection are needed as well as possible prevention strategies. A national prevention effort should be guided by the results of research that addresses current knowledge gaps.
