SALOMON, María Cristina et al. Trichomonas vaginalis prevalence in sex workers. Medicina (B. Aires) [online]. 2011, vol.71, n.5, pp.429-431. ISSN 0025-7680.

Trichomoniasis is a sexually transmitted infection (STI) usually associated to vaginitis, urethritis, cervicitis and pelvic inflammatory disease, which can cause infertility. The aim of this retrospective longitudinal study was to determine Trichomonas vaginalis prevalence in a population of male and female sex workers in Mendoza, Argentina. A cohort of 720 people who attended the STI Program in this province was retrospectively analyzed. From February 2007 up to June 2009, 1692 samples were processed using a reposition sampling method. The age and sex distribution of the population was: 687 women/33 men, from 15 to 65 years old. Trichomoniasis prevalence determined for this population at risk was 7.6% in women only, men did not present infection. The high prevalence shown for this risk group suggests a great vulnerability of this population to contract other more serious STIs. In another sense, it also shows a remarkable lack in the use of mechanical barriers to prevent sexually transmitted diseases (STDs). The present research justifies the elaboration of standardized procedures guide to diagnose T. vaginalis within the framework of the Reproductive Health Program (PROSAR).
