" --- Background Public health surveillance systems are essential tools for monitoring disease prevalence and tracking intervention effectiveness. In Senegal, such systems play a vital role in improving healthcare delivery. Purpose and Objectives To evaluate the methodological rigor of public health surveillance systems in Senegal using difference-in-differences (DiD) models, with a focus on measuring clinical outcomes. Methodology The review will analyse existing data from Senegalese public health surveillance systems. DiD model will be applied to assess changes in clinical outcomes over time. Findings A notable finding is a 20\% increase in vaccination coverage among children aged 1-5 years post-intervention, with robust
