Aim of the study: To identify risk factors associated with measles cases in the Odienné health district from 2019 to 2023. Population and methods: This retrospective cohort study, conducted from July to October 2024, analyzed measles surveillance data in the Odienné health district over the period 2019-2023. Cases were selected exhaustively, and data extracted via MAGPI software. A bivariate analysis with Chi-squared tests was performed. Multivariate analysis was performed using logistic regression in IBM-SPSS software. Significance thresholds were set at α= 5% and P-value <0.05. Variables included socio-demographic factors, vaccination status. The study complied with ethical standards and data confidentiality. Results: The study included 358 cases of measles, including 40 confirmed cases. Analysis revealed a vaccination coverage of 78% in 2022, with children aged 5 to 15 accounting for 40.8% of cases. A peak in measles prevalence was observed in 2022. The analysis also revealed that type of residence (rural area) was the only factor significantly associated with high measles prevalence (OR = 0.34; CI: [0.18-0.67]; p = 0.001). Conclusion: Measles remains a public health challenge in the Odienne health district. Boosting vaccination coverage, improving epidemiological surveillance and adapting interventions to local contexts are essential to controlling the disease. Cross-border collaboration and multi-sectoral commitment are necessary for an effective and sustainable response.
