Abstract:
Trichomonas vaginalis is the most prevalent nonviral sexually transmitted infection, affecting an estimated 3.7 million people in the United States. Although trichomoniasis is common, it has been considered a "neglected" sexually transmitted disease, due to limited knowledge of its sequelae and associated costs. This article reviews current epidemiology, pathophysiology, diagnostic methods, clinical management recommendations and special considerations, research on associated conditions and costs, prevention strategies, and controversies regarding trichomoniasis.
