Abstract
Public health surveillance systems are crucial for monitoring infectious diseases and ensuring timely interventions in resource-limited settings such as Rwanda. A randomized field trial was conducted to assess the performance and cost-effectiveness of the surveillance system. Data collection included both quantitative and qualitative methods. The study found that the average response time for reported cases fell within ±15% of the expected mean, indicating a well-functioning system with acceptable variability. The randomized field trial confirmed the robustness of the surveillance system in Rwanda, offering insights into its cost-effectiveness and operational efficiency. Further research should focus on scalability and integration with existing health information systems to enhance overall public health outcomes. 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.
