[Prevalence of sexually transmitted diseases among pregnant Tunisian women and validation of a clinical algorithm proposed by WHO for the management of sexually transmitted diseases].

Abstract

The objectives of our study are to assess the prevalence of STD agents in Tunisia and to validate the WHO algorithm of STD management. The most frequent STD agents are Trichomonas vaginalis and Chlamydiae trachomatis, respectively with a prevalence of 5.6% and 1.7%. The assessment of the syndromic approach shows that the sensitivity and specificity of the WHO algorithm can be improved by the introduction of risk factors. The training of health care service providers and the use of an algorithm including risk factors can improve this approach, which is useful when laboratories services are not available.
