Vulvovaginal infections encompass a wide array of specific conditions, each of which has different presenting symptoms.

• Unsolicited reporting of abnormal vaginal discharge suggests trichomoniasis or bacterial vaginosis (BV).
  • - Trichomoniasis is characterized by vulvar irritation and a profuse white or yellow, homogeneous vaginal discharge with a pH that is typically ≥5.
  • - BV is characterized by vaginal malodor and a slight to moderate increase in white or gray, homogeneous vaginal discharge that uniformly coats the vaginal walls and typically has a pH >4.5.
  • - Vaginal trichomoniasis and BV early in pregnancy are associated with premature onset of labor.
• Vulvar conditions such as genital herpes or vulvovaginal candidiasis can cause vulvar pruritus, burning, irritation, or lesions as well as external dysuria (as urine passes over the inflamed vulva or areas of epithelial disruption) or vulvar dyspareunia.
