The most common vaginal infection in women between the ages of 15 years and 44 years (CDC, 2016). Occurs when the normal vaginal flora (lactobacillus) is displaced by an overgrowth of bacteria not normally found in high concentrations in the vagina. May be symptomatic or asymptomatic. Symptoms include a malodorous, thin, white or grey vaginal discharge; pain, itching, and burning in the vagina; burning when urinating; itching within the vaginal introitus; and some women have a strong fish-like odor (especially after vaginal sexual activity).
