Sub-Regional Variations in Sexually Transmitted Infections Manifesting as Vaginitis among Reproductive-Aged Women in Sub-Saharan Countries

Sexually transmitted infection refers to a group of clinical syndromes that can be acquired and transmitted through sexual activity and are caused by a variety of pathogens such as bacteria, fungi, viruses, and parasites. Methods: Demographic and Health Survey data involving women aged 15–49 years were analyzed for this study. The surveys were conducted between 2006–2021. Statistical significance was determined at p < 0.05. Results: From the results, Liberia (33.0%), Mali (14.0%), Guinea (13%), Uganda, and Sierra Leone (12.0% each) had the highest STI prevalence. Prominently from Western sub-Saharan Africa sub-region, Liberia (40.0%), Guinea (31.0%), Mali (28.0%), Cote d’Ivoire (24.0%), Ghana (23.0%) and Mauritania (22.0%) have the highest prevalence of reporting a bad smelling or abnormal genital discharge. In addition, Liberia (30.0%), Uganda (13.0%) and Malawi (10.0%) have the highest prevalence of reporting genital sores or ulcers. Liberia (48.0%), Guinea (34.0%), Mali (32.0%), Ghana and Mauritania (25.0% each) and Uganda (24.0%) reported the leading prevalence of STI, genital discharge, or a sore or ulcer. Conclusion: The prevalence of vaginitis varied according to women’s characteristics. In many countries, younger women, urban dwellers, educated women, rich and unmarried women reported a higher prevalence of STI, genital discharge, or a sore or ulcer. Women should be educated on the advantages of proper hygiene, and prevention and control of STIs. Program planners and policymakers should assess and improve the collaboration and coordination of nutritional and family health programs aimed at addressing women’s health issues.
