Bacterial Vaginosis (BV)
Bacterial Vaginosis (BV) is a condition in women where the balance of bacteria normally found in the vagina is disrupted. The cause of this imbalance is not fully understood. BV is not a sexually transmitted disease in the conventional sense – any woman can get BV, even those who have never had sex. However, sexually active women are at increased risk of BV and the reasons for this are unclear.

- Abnormal vaginal discharge – white or grey, watery or foamy
- Pain during urination
- Vaginal itching
It is unclear what causes the imbalance in vaginal bacteria that leads to BV. However, some behaviors can increase a woman’s risk of BV:
- Having a new sex partner
- Having multiple sex partners
- In pregnant women, having BV can increase risk of preterm birth and low birth weight.
- Having BV makes it easier to transmit or acquire HIV during sex.
- Avoiding vaginal sex may reduce a woman’s risk of getting BV.
- Limit the number of sex partners.
- To maintain “healthy” vaginal bacteria, do not douche.
Testing and Treatment
- Get a test from a medical provider if infection is suspected.
- BV can be cured using medication prescribed by a medical provider.
- Male sex partners do not need to be treated at the same time.
NOTE: BV can recur after treatment.
