All suspected measles cases with available serological results recorded in Benin’s national surveillance database between 2020 and 2024 were analyzed. A confirmed case was defined as any suspected case with a positive immunoglobulin M result. Socio-demographic characteristics, vaccination status, and biological data were described using R version 4.3.3. When missing values were present, they were categorized as a separate category for the corresponding variable. Variables with a p-value < 0.20 in bivariate analyses were included in a multivariable logistic regression model to estimate adjusted odds ratios (aOR) with their 95% confidence intervals (95% CI). A p-value < 0.05 was considered statistically significant.
A total of 3,233 suspected measles cases were reported between 2020 and 2024, of which 36.3% were confirmed. Children aged 1-5 years accounted for 53.2% of confirmed cases, 78.9% resided in rural areas, and only 15.1% were vaccinated. The annual incidence rate increased from 0.1 to 3.5 cases per 100,000 population between 2020 and 2024. The case fatality rate was 1.4%. Vaccination (aOR: 0.43; 95% CI: 0.35–0.53) and living in urban areas (aOR: 0.66; 95% CI: 0.55–0.79) were protective against measles. Compared with 2020, the risk of measles was higher in 2022 (aOR: 7.25; 95% CI: 4.09–14.1), in 2023 (aOR: 8.5; 95% CI: 4.83–11.4), and in 2024 (aOR: 11.3; 95% CI: 6.42–21.9).
