Bacterial vaginosis - Anogenital in
BV is the most common etiology of vaginal discharge in women of childbearing age; however, a majority of patients are asymptomatic. In the United States, the estimated prevalence is anywhere from 11% to 33% of women, with some difference in prevalence among ethnicities (a higher rate in patients of African descent has been observed).
The diagnosis and management of BV is important for several reasons, including:
- BV increases the risk of acquisition of STIs including HIV, gonorrhea, Chlamydia, Trichomonas, human papillomavirus (HPV), and herpes simplex virus type 2 (HSV-2).
- BV has been associated with adverse pregnancy outcomes (premature membrane rupture, early labor, preterm birth, and postpartum endometritis).
