Overview
Trichomoniasis is the most common curable STD in young, sexually active women. An estimated 7.4 million new cases occur each year in the United States. In 2008, the incidence of trichomoniasis was estimated to be 358 cases per 100,000 individuals in the United States.[1] Females are more commonly affected with trichomoniasis than males.[2] Trichomoniasis usually affects African American individuals. Caucasian individuals are less likely to develop trichomoniasis. In the United States, the highest prevalence of trichomonas infection in women is seen among African-Americans, with rates ranging from 13–51%.[3]
Epidemiology and Demographics
The worldwide incidence and prevalence of trichomoniasis is reflected in the following table:[4]

Age
Trichomoniasis occurs most commonly among women aged 20-45 years.[7]
Gender
Females are more commonly affected by trichomoniasis than males.[2]
