Bacterial Vaginosis Classification and Management

Introduction to Bacterial Vaginosis

The Centers for Disease Control and Prevention (CDC) explicitly states that "bacterial vaginosis is not usually transmitted sexually," though it acknowledges the condition is included in STD treatment guidelines because these infections are frequently diagnosed during STD evaluations 1, 2
The CDC notes that "it is unclear whether BV results from acquisition of a sexually transmitted pathogen," indicating the mechanism remains incompletely understood despite strong epidemiological associations with sexual behavior 1, 2

BV results from replacement of normal H2O2-producing Lactobacillus species with high concentrations of anaerobic bacteria, Gardnerella vaginalis, and Mycoplasma hominis—representing an ecological shift rather than acquisition of a single sexually transmitted pathogen 1, 2

Traditional guidelines state that routine partner treatment is not recommended, as six older randomized trials showed no benefit in preventing recurrence 3, 4
The CDC recommends that women with bacterial vaginosis be counseled on the risks and benefits of treatment, including the potential for recurrence 1, 2
The American College of Obstetricians and Gynecologists (ACOG) suggests that treatment of male sex partners has not been beneficial in preventing BV recurrence, which is a critical distinction from true sexually transmitted infections where partner treatment is essential 3

When discussing BV with patients, emphasize that while it's not a classic STD requiring partner notification and treatment like gonorrhea or chlamydia, sexual activity does influence its development and recurrence 1, 2
Don't automatically treat partners as you would for true STDs—this has not been shown effective in most cases and represents unnecessary antibiotic exposure 1, 2, 4
