Trichomonas vaginalis is a sexually transmitted protozoan pathogen that may cause more than one-half of all curable sexually transmitted genital infections worldwide. Women with trichomoniasis are often asymptomatic, but they may develop vaginal malodour, discharge, erythema, or itching, and their male or female sexual partners may also be infected, although urethritis in men is less likely to cause symptoms. Women with trichomoniasis have an increased risk of HIV acquisition, HIV shedding, pelvic inflammatory disease, and preterm birth. For diagnosis, rapid antigen detection, culture, and polymerase chain reaction (PCR) methods have advantages over conventional microscopy, but are more expensive. Oral metronidazole is usually an effective treatment, with both sexual partners needing to be treated to prevent reinfection.
