Trichomoniasis
Introduction
Trichomoniasis is a sexually transmitted infection of the vagina or urethra that is caused by the protozoaTrichomonas vaginalisand that causes vaginal irritation and discharge and sometimes urinary symptoms. Women may have a greenish yellow, frothy, fishy-smelling vaginal discharge with irritation and soreness in the genital area. Men usually have no symptoms, but a few have a frothy discharge from the penis and mild pain or discomfort during urination. Examination of a sample of the discharge under a microscope usually enables doctors to identify trichomoniasis. Infected people and their sex partners are treated with antibiotics. Using condoms during genital sex can help prevent passing trichomoniasis and other sexually transmitted infections (STIs) from one person to another. (See also Overview of Sexually Transmitted Infections (STIs) .) commonly causes an STI of the vagina in women and an STI of the urinary tract in men and women. Women are much more likely to develop symptoms. About 20% of women develop trichomoniasis of the vagina ( Trichomonal Vaginitis ) during their reproductive years. People with trichomoniasis may also have Gonorrhea or other STIs.
