Trichomoniasis is the most prevalent non-viral sexually transmitted infection worldwide. It is
associated with a high prevalence of coinfection with other sexually transmitted diseases and
can be identified in 30 to 40% of male sexual partners of infected women. Some possible consequences
of trichomonaisis in women include pelvic inflammatory disease, post-hysterectomy
cellulitis, and preterm birth; some possible consequences in men include prostatitis, infertility,
and prostate cancer. Trichomonas infection in women appears to increase the risk of sexual acquisition
of the HIV, preterm birth, and other adverse pregnancy outcomes
Clinical manifestations in women range from an asymptomatic carrier state to a severe, acute,
inflammatory disease. Signs and symptoms include a purulent, malodorous, thin discharge with
associated burning, pruritus, dysuria, frequency, and dyspareunia.
