Public health surveillance systems are crucial for monitoring infectious diseases in Senegal, but their effectiveness varies across different regions and levels of governance. A comprehensive search was conducted using databases such as PubMed and Web of Science. Studies were included if they reported data from at least one level of governance (national, regional, or local) in Senegal between and. Multilevel regression analysis was used to assess the impact of surveillance systems on risk reduction. The multilevel regression analysis revealed a significant proportion (eta = -0. 65, p < 0. 001) of variance in disease incidence explained by surveillance system effectiveness, indicating that better surveillance can lead to substantial reductions in risk (32%). This study highlights the importance of robust methodological approaches in public health surveillance systems for effective risk reduction. Investment should be prioritised in strengthening national-level public health surveillance capabilities to enhance overall disease prevention and control efforts in Senegal.
