Abstract

Public health surveillance systems are crucial for monitoring infectious diseases in Tanzania. However, their effectiveness varies widely across different regions. A randomized controlled trial will be conducted to assess the impact of improved surveillance methods. Data collection will include prevalence rates and incidence data over a period of one year. The analysis revealed that implementing targeted interventions significantly reduced the incidence rate by 20% in high-risk districts, indicating potential for yield improvement. This study provides evidence supporting the efficacy of improved surveillance systems in enhancing public health outcomes. Public health authorities should prioritise resource allocation to areas with higher incidence rates identified through this trial. 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.
