Prévalence de Chlamydia trachomatis, Neisseria gonorrhoeae, Treponema pallidum et du VIH chez les femmes à Kara, en 2022.

Abstract

Objective of the study: To estimate the prevalence of four STIs in women of reproductive age in the Kara region.

Methods: A cross-sectional study was conducted in March 2022. Data were collected using a standardized questionnaire. Screening for HIV and syphilis was performed using the SD-BIOLINE HIV/Syphilis Duo® rapid tests. The GeneXpert PCR technique was used to test for Chlamydia trachomatis and Neisseria gonorrhoeae. The prevalences of STIs (Chlamydia trachomatis, Neisseria gonorrhoeae, Treponema pallidum, and HIV) were reported with 95% confidence intervals.

Results: A total of 300 women with a median age of 32 years (interquartile range 24–39) were included. Of these, 25.7% had consulted a gynecologist in the last twelve months. The prevalence of Chlamydia trachomatis was 4.3% (95% CI [2.4–7.5]); Neisseria gonorrhoeae 3.3% [95% CI: 1.7–6.2], Treponema pallidum 0.3% [95% CI: 0.02–2.1] and HIV 3.7% [95% CI: 1.9–6.7]. Three cases of co-infection with Neisseria gonorrhoeae and Chlamydia trachomatis were reported; no cases of co-infection with HIV and bacterial STIs were reported.

Conclusion: This study confirms the women’s limited access to gynecological consultations, the low circulation of syphilis, and the presence of Neisseria gonorrhoeae and Chlamydia trachomatis in women of reproductive age in the Kara region. An STI surveillance system is needed to improve STI management among this population.
