Trichomonas Vaginalis

Also known as Trichomoniasis or Trich, this vaginal infection can cause the vulva to become sore, red and inflamed. The most notable symptom is a foamy, yellow greenish vaginal discharge. In some women it also hurts to urinate. The organism that causes these symptoms is a parasite in the vaginal mucus. It spreads through penetrative vaginal sex and the exchange of vaginal fluid, for example, through sharing sex toys.

Treatment is usually antibiotics taken by mouth. To prevent re-infection, your sexual partner(s) should also be treated. Infection in men often does not cause any symptoms, so testing, treatment and the use of condoms is advised. Avoid sharing sex toys during treatment and always clean them thoroughly.
