Prevalence of genital Chlamydia trachomatis infection among patients attending a gynecological clinic in a tertiary hospital

Background: Chlamydia trachomatis is the most common cause of sexually transmitted infections in the world. The organism causes silent infection in women and could remain unnoticed for a very long time. Nearly 80% of women are asymptomatic. It is an established and recognized cause of pelvic inflammatory disease, ectopic pregnancy, and infertility among women. In most parts of Nigeria, including the study area, the organism is not routinely screened for, hence the paucity of information about its prevalence. Objectives: The objectives of this study were to determine the prevalence and risk factors associated with genital C. trachomatis infection among women attending the Gynaecological Clinic of Usmanu Danfodiyo University Teaching Hospital (UDUTH), Sokoto, Nigeria. Materials and Methods: A prospective study was carried out among new patients attending the Gynaecological Clinic of UDUTH, Sokoto. The women were consecutively recruited as they presented to the clinic until the desired sample size was achieved. A structured questionnaire was administered, and related information and consent were obtained. Endocervical swab was collected and tested using Eugene Chlamydia Rapid Test Device following manufacturer's instructions. Results: Samples were collected from a total of 400 women aged between 15 and 49 years. The prevalence of genital C. trachomatis among gynecological patients was 3.5%. The risk factors identified include age of patients below 29 years, early age of onset of sexual activity, and marital status. Conclusion: The study showed that the prevalence of genital C. trachomatis was low. The rate was higher among respondents with infertility. There is a need for routine screening of patients with infertility.
