Trichomoniasis Statistics										Related Pages
										In the United States, there were an estimated 2.6 million trichomoniasis infections in 2018. Trichomoniasis can increase the risk of getting or spreading HIV, and pregnant women with the infection are more likely to have their babies too early (preterm delivery) and with a low birth weight.

Prevalence
STI Prevalence, Incidence, Cost Estimates (January 25, 2021)The prevalence of *Trichomonas vaginalis* in the United States is 2.1% among women ages 14-59, and 0.5% among men based on a nationally representative sample of people who participated in NHANES 2013-2016. The following are other findings from this study:
Prevalence was 9.6% for African American women, 1.4% for Hispanic women, and 0.8% for non-Hispanic white women.
For men and women, increasing poverty level, lower educational level, unmarried status, and having been born in the U.S. are associated with *T. vaginalis*infection.
For women, younger age at first sex, greater number of sex partners, and a history of chlamydia infection in the past 12 months are associated with *T. vaginalis* infection.
