The health and demographic surveillance system on Rusinga Island, Western Kenya, was initiated in 2012 to facilitate a malaria intervention trial: the SolarMal project. The project aims to eliminate malaria from Rusinga Island using the nationwide adopted strategy for malaria control (insecticide-treated bed nets and case management) augmented with mass trapping of anopheline mosquitoes. The main purpose of the health and demographic surveillance is to measure the effectiveness of the trial on clinical malaria incidence, and to monitor demographic, environmental and malaria-related data variables.

- Large reductions in malaria transmission have occurred due to long-lasting insecticidal bed nets and indoor spraying, but significant localized transmission persists, necessitating tailored interventions based on local contexts.
- Researchers conducted surveys on Rusinga Island, Kenya, testing over 3,600 individuals and analyzing demographic and environmental data to understand spatial variations in malaria prevalence.
- Results showed a 24% prevalence rate, with distinct clusters of higher cases, and indicated that socio-economic factors and environmental conditions play crucial roles in sustaining malaria transmission.
Background: Health in low and middle income countries is on one hand characterized by a high burden associated with preventable communicable diseases and on the other hand considered to be under-documented due to improper basic health and demographic record-keeping. health and demographic surveillance systems (HDSSs) have provided researchers, policy makers and governments with data about local population dynamics and health related information. In order for an HDSS to deliver high quality data, effective organization of data collection and management are vital.
