Prevalence of sexually transmitted diseases (STD) among women in a suburban Sudanese community.

338 women with age ranging from 15 to 69 years in a suburban Sudanese community were randomly selected and studied. Urine sample, high vaginal swabs and blood samples were investigated for bacterial vaginosis, candidiasis, trichomoniasis, gonorrhoea, HIV and syphilis. The sensitivity and specificity of some laboratory tests were evaluated. Bacterial vaginosis was found in 17.2% of the subjects, candidiasis in 10.1%, trichomoniasis in 7.7%, gonorrhoea in 1.2%, HIV in 1.2% and syphilis in 0.9% of the subjects. The sensitivity and specificity of amine test as a criterion for diagnosing bacterial vaginosis was 58.6% and 73.2%, respectively. The respective values of clue cells in wet preparation were 43.1% and 99.6%. The vaginal discharge in women with bacterial vaginosis lacked pus cells unless associated with concurrent infection.
