Trichomoniasis is a sexually transmitted disease (STD) caused by a small organism called Trichomonas vaginalis. Women are most often affected by this disease, although men can become infected and pass the infection to their partners through sexual contact.


Trichomoniasis is the most common curable STD in young, sexually active women. An estimated 7.4 million new cases occur each year in women and men.


Men often do not have symptoms of trichomoniasis and usually do not know they are infected until their partners need treatment. But when symptoms do occur, they include:

• Irritation inside the penis

• Mild discharge

• Slight burning after urination or ejaculation

• Many women do have signs or symptoms of infection. Symptoms in women can include:

• Greenish-yellow, frothy vaginal discharge with a strong odor

• Painful urination

• Vaginal itching and irritation

• Discomfort during intercourse

• Lower abdominal pain (rare)

Symptoms usually appear within five to 28 days of exposure in women.



How Is Trichomoniasis Treated?

Usually an oral antibiotic called metronidazole (Flagyl) is given to treat trichomoniasis. Before taking this drug, it is very important to let your doctor know if there is any chance that you could be pregnant, because the drug could harm the baby.

Your partner should also be treated at the same time to prevent reinfection and further spread of the disease. In addition, persons being treated for trichomoniasis should avoid sex until they and their sex partners complete treatment and have no symptoms. It is important to take all of your antibiotics, even if you feel better.
