Trichomonas is a single-celled organism that causes a type of infection in the birth canal, or vagina, called trichomoniasis. This is a common vaginal infection in sexually active women. It is passed from person to person during sex. The male sex partner is often infected, but may not have symptoms. Symptoms in women include:
* itching and burning at the outside opening of the birth canal,
* painful intercourse,
* painful or more frequent urination,
* a heavy, unpleasant smelling greenish-yellow discharge.

If you have these problems, your healthcare provider can help. You will need an exam to test the discharge and to make sure that there are no other infections present. Treatment will be needed for both you and your partner. If you are pregnant, you will usually be treated after the first part of your pregnancy. For most people, the symptoms disappear in less than one week. Reinfection may take place if your partner is not treated, or if you do not complete the course of treatment. Be sure to call your healthcare provider if your symptoms do not resolve.

Trichomoniasis is transmitted like other sexual diseases, through unprotected sexual intercourse, without a condom. Abstinence, which means having no sex or monogamy or having one faithful committed partner, will protect you from this organism. To learn more about safer sex, call your local health department for materials, or visit your local bookstore.
