Abstract
Public health surveillance systems are critical for monitoring diseases and managing public health crises in Senegal. A randomized field trial was conducted to assess the performance and efficiency of public health surveillance systems. Data collection included surveys, observational studies, and cost analysis methods. The study identified a significant improvement in reporting accuracy from baseline to post-intervention (p < 0.05), with an increase in timely disease reports by 30%. The randomized field trial demonstrated the effectiveness of enhanced public health surveillance systems, showing improved cost-effectiveness and timely intervention. Recommendation for stakeholders includes continued investment in training personnel and infrastructure to maintain these advanced surveillance capabilities. Treatment effect was estimated with $\text{logit}(p<em>i)=\beta</em>0+\beta^\top X_i$, and uncertainty reported using confidence-interval based inference.
