Trichomonas Vaginitis Overview

What is trichomonas vaginitis?
A woman with trichomonas vaginitis has inflammation of the lining to the vagina, caused by an infection with the parasite, Trichomonas vaginalis. Trichomonas vaginitis is a sexually transmitted disease. About 1 out of 150 women develop trichomonas vaginitis each year in the US.

What are the symptoms of trichomonas vaginitis?
About 50 percent of women who are infected with trichomonas have no symptoms. Symptoms of trichomonas vaginitis may include a vaginal discharge, vaginal itching, vaginal pain, a vaginal odor, and pain during intercourse. Rarely, a woman may also have pain during urination.

How does the doctor treat trichomonas vaginitis?
Treatment for trichomonas vaginitis may include antiparasitic medications. The sexual partner must be treated also, in order to prevent re-infection.
