Abstract
Public health surveillance systems in Senegal have been established to monitor disease outbreaks efficiently. However, their effectiveness varies across regions and time periods. A Bayesian hierarchical model was utilised to analyse data from multiple regions, accounting for spatial and temporal variations. Model uncertainty was quantified through credible intervals. The analysis revealed significant reductions in disease detection times by approximately 35% across the surveillance systems, with substantial heterogeneity observed between regions. Bayesian hierarchical modelling provided a robust framework to assess risk reduction strategies and highlighted the need for localized interventions. Implementing targeted improvements based on regional findings will enhance overall surveillance system performance in Senegal.
