Quick answers about BV, yeast, and vaginal itching

Short, citable answers. Last reviewed: October 25, 2026. Sources: CDC, ACOG. Education only, not medical advice.

Is bacterial vaginosis (BV) a yeast infection?

No. BV is an imbalance of vaginal bacteria, often with a thin gray-white discharge and a fishy odor. Yeast infections are caused by Candida fungus and usually cause itching and thick white discharge.

Is BV an STI?

BV is not classified as an STI, but it is linked to sexual activity and can be more common with new or multiple partners. Source: CDC.

Can BV come back after treatment?

Yes. Recurrence is common; many people see BV return within months. A clinician can discuss longer treatment regimens.

Do I need a doctor to confirm a yeast infection?

If it is your first time, symptoms are severe, or you have had repeated episodes, see a clinician. Self-treating the wrong condition is common.

Are boric acid suppositories safe?

Boric acid is poisonous if swallowed, should never be used by mouth, and should be avoided in pregnancy. Talk to a clinician first.

Is itching always an infection?

No. Contact dermatitis, urine-leakage dermatitis, eczema, and psoriasis can all cause vulvar itching.

Is my partner the problem if my BV or yeast keeps coming back?

Usually it is not that simple. Yeast infections are not generally considered sexually transmitted, and BV is not treated as a simple partner-to-partner infection. See /is-it-contagious/ for details.
