Trichomoniasis (or Trichomonas vaginalis, TV) is an infection of the vagina and is caused by a parasite (a flagellate protozoan) that lives in the lower genitourinary tract. The disorder can involve the vagina, urethra and bladder in women. In men, it can affect the prostate gland and urethra.
Symptoms and signs
The symptoms varies from women to women. Some may not have any symptoms at all and may not be aware of this infection. Infected men may have no symptoms as well. Typical symptoms are:
- Vaginal discharge which is foul-smelling, frothy and it is most noticeable after sexual intercourse or after menses. The discharge color may be greenish or yellowish.
- Vaginal itching and discomfort.
- Redness of the vaginal lips (the labia) and vagina.
- Painful urination especially if the labia is inflamed and the urine touches the surrounding area.
This is due to a parasite called Trichomonas vaginalis. The transmission from person to person is almost exclusively via sexual intercourse. It may live in its host without producing symptoms. Since it is usually transmitted sexually, both the sexual partners must receive treatment to eliminate it completely.
