Trichomoniasis, or Trich, is a common sexually transmitted disease that affects both women and men, though it is more common in women. It is caused by the bacteria Trichomonas vaginalis, which is an anaerobic parasite. Although most infections are acquired through sexual contact, it is possible in some cases to get Trich from bathroom facilities, wet towels, or wet swimsuits.

What are the signs and symptoms of Trich?
The signs and symptoms of Trich in women include a frothy, yellow-green vaginal discharge with a strong odor. Vaginal itching, pain during urination, and pain during intercourse may also be present. Men with Trich may not have any signs or symptoms. However, signs and symptoms of infection in men include irritation inside the penis, discharge from the penis, and burning after ejaculation. Symptoms usually occur 5-28 days following exposure.
How is Trich diagnosed?
Only your healthcare provider can make a definitive diagnosis of Trich. A pelvic exam may show small red ulcerations on the vaginal wall or cervix. A sample of vaginal or urethral fluid is looked at under the microscope to identify the parasite that causes Trich
How is Trich treated?
Trich is not responsive to over the counter medications. Your healthcare provider will give you an oral pill called metronidazole, or Flagyl, to treat the infection. It is important that your sexual partner (s) also be treated for Trich, as re-infection can occur.
