Bacterial vaginosis (BV) is a common condition that is related to alterations in the normal vaginal flora. It is the most common cause of vaginitis and has a recurrence rate of approximately 20%-40% at one month.
Information on the prevalence of BV is incomplete since BV is not reportable. Some studies have shown a 5%-25% prevalence in college students and 12%-61% prevalence in patients at an STD clinic.
Organisms associated with BV do not persist in the male urethra, but may be present under the foreskin of uncircumcised men. BV has been identified in female same-sex partnerships.
BV has been linked to premature rupture of membranes, premature delivery, low-birthweight delivery, acquisition of HIV, development of pelvic inflammatory disease (PID), and post-operation infections after gynecological procedures. Occurrence of BV
may be related to sexual activity, but BV is not considered a sexually transmitted disease.
