STD Home > Important Information on Trichomoniasis
A healthcare provider can diagnose trichomoniasis by performing laboratory tests on fluid samples from the vagina or penis. When women are infected with the parasite, a pelvic examination reveals red sores on the cervix or inside the vagina.
Because men can transmit the disease to their sex partners even when they don't have any symptoms, health experts recommend that both partners be treated to get rid of the parasite. Healthcare providers usually use metronidazole in a single dose to treat people infected with the parasite. However, even with successful treatment, a person can get trichomoniasis again.

The surest way to avoid any STI, including trichomoniasis, is to abstain from sexual contact or to be in a long-term, mutually monogamous relationship with a partner who has been tested and is known to be disease-free. Using a latex male condom consistently and correctly during sex may help prevent spread of the disease as well.
Research has shown a link between trichomoniasis and two serious complications. Scientific studies suggest that the disease is associated with at least a three- to fivefold increased risk of HIV transmission, and may cause a woman to deliver a low-birth-weight or premature infant (see Trichomoniasis and Pregnancy). Scientists need to do additional research to fully explore these relationships.
