Trichomoniasis is more common in women than men, and older women are more likely than younger women to have been infected.


The prevalence of Trichomonas vaginalis infection in the United States is estimated to be 2.3 million (3.1%) among women ages 14-49, based on a nationally representative sample of women who participated in NHANES 2001–2004. The following are other findings from this study.
  • Most women found to have trichomoniasis (85%) reported no symptoms.
  • Women with no history of sexual intercourse can still be affected by trichomoniasis (1.0%), as can pregnant women (3.2%), and women who have ever been pregnant (4.1%).
  • African American women had a prevalence of 13.3%, white women prevalence of 1.3%, and Mexican American women prevalence of 1.8%.
  • Prevalence of trichomoniasis increases with age and lifetime number of sexual partners among African American women.
