Risk of having a sexually transmitted infection in women presenting at a termination of pregnancy clinic in Pretoria, South Africa

Abstract

This study was undertaken to assess the risk of being infected with a known sexually transmitted pathogen at the time of presentation for termination of pregnancy. Endocervical and vaginal swabs were collected for the diagnosis of Neisseria gonorrhoeae, Chlamydia trachomatis and Trichomonas vaginalis. Single infections were found in 21.5% of the women, with C. trachomatis being the commonest (10.0%). Mixed infections were found in nine women, with trichomoniasis and chlamydial infections in six. During speculum examination, vaginal discharge was observed in 73% of the women. The commonest organism detected in patients with vaginal discharge was C. trachomatis (11.6%), while T. vaginalis (11.1%) was the most common in women without visible vaginal discharge. No significant differences were found when comparing symptomatic and non-symptomatic women. This study strongly recommends that women presenting for termination of pregnancy be screened for STIs and receive relevant sexual health education.
