The prevalence of sexually transmitted diseases (STDs) and the frequency of genitourinary symptoms and signs were assessed in 1233 female prostitutes aged 18-45 years, of mean age 26, in Yaounde and Douala. Researchers recorded the physical signs and symptoms experienced by the study subjects within 14 days prior to the physical examination provided as part of the study. The women were tested for gonorrhea, chlamydia infection, and trichomoniasis, with doctors' clinical impressions compared to laboratory test findings. 20% had cervicitis; gonorrhea (11%), chlamydia (12%), or both (3%). 20% had a positive wet mount test for trichomoniasis; 10 subjects were diagnosed with gonorrhea, chlamydia, and trichomoniasis; 65.1% reported abnormal vaginal discharge; and 44.7% reported pelvic pain. Clinical diagnosis for cervicitis and trichomoniasis in this study had sensitivities of less than 50% and specificities of greater than 65%. STDs are therefore common among prostitutes in Cameroon and clinical diagnosis was not an accurate predictor of infection at the individual level.
