Prevalence of Trichomonas Vaginalis in US males

Clin Infect Dis; ePub 2018 Jun 9; Daugherty, et al

The rates of trichomonas infection in US males are lower than in women, with infection strongly associated with black males, herpes simplex virus-2 (HSV-2) infection, and other factors known to increase sexually transmitted infection (STI) rates. Utilizing the NHANES database, researchers searched for all men aged 18-59 years during 2013-2016. During these years, the survey included urine testing for trichomonas infection using PCR. Information was also obtained regarding patient demographics and other STIs. They found:

  • Overall, 0.49% of men aged 18-59 years tested positive for trichomonas infection.
  • African American men had the highest rate at 3.6%.
  • There was no significant association with trichomoniasis and age.
  • Higher rates of infection were observed in smokers, HSV-2 infection, men who had sex at an earlier age, less frequent condom usage, and in those with more lifetime sexual partners.
