Health and Demographic Surveillance System
Medical Research Council
London School of Hygiene and Tropical Medicine
The Unit maintains three Health and Demographic Surveillance Systems in Basse, Farafenni, and West Kiang. The HDSS collects data on vital events, namely births, deaths, migrations, pregnancy, educational level, ethnicity, vaccination status, socio economic status and cause of death (through Verbal Autopsies) using the electronic data capture (EDC) method via RedCap application. We aim to provide baseline data, sampling frame and identify clinical cases/study subjects to scientists for community-based research. We also provide a denominator for estimating impact studies, generate longitudinal information on the health of the population and provide quantitative evidence for scientific investigations as well as monitor demographic and mortality trends in populations.
