Background: trichomoniasis is recognized as a major sexually transmitted disease (std) in the world and has the highest prevalence and incidence of std. the prevalence strongly is related to cultural and social norms in different societies, in relation to sexual partnership, monogamy, or polygamy. our objective was to describe the frequency and natural history of infection and correlation of clinical signs with parasite detection.methods: from february 2006 to march 2007, in a cross sectional study, clinicaland wet mount examination of vaginal smear along with culture were performed on 683 women attending to private outpatient clinics in hamadan, western iran. trichomoniasis was diagnosed based on major clinical symptoms. diagnosis was confirmed using wet mount microscopically and culture in diamond medium. results: only 2.2% of patients with clinically diagnosed trichomonal vaginitis were positive for trichomonas vaginalis by wet smear and culture. the mean age of patients was 33.6±9.7 yr, and majority of them were married and nonpregnant. some (5 patients) infected cases were divorced and others (7 patients) husband were car driver. there was not statistically significant relationship between clinical diagnosis and laboratory findings (p>0.5), because the most of patients diagnosed trichomoniasis, were infected by candida or other vaginal infections. conclusion: because of special cultural background, the vaginal trichomoniasis has minor importance problem in this population and clinical diagnosis is not efficient for treatment decision.
