Current Work
Kilifi surveillance system provides a platform that supports research by 1) providing sampling frame to the nested studies within the surveillance (KHDSS) area. 2) monitor health and demographic transition of the residents of KHDSS area and 3) evaluating impact of public health interventions such as the rollout of new vaccines. The Kilifi surveillance system is an integrated system of the household surveillance (HDSS), facility-based surveillance and laboratory tested samples Collaborations Kilifi County (Department of health), Kenya civil registration services, Kenya National Bureau of Statistics, INDEPTH Network, Other DSS sites in KenyaCollaborations
