Nesstar Publisher Wellcome Trust Karonga Prevention Study iSHARE2 Helpdesk Demographic Surveillance Devloped in Ishare2 workshop Dubai 2015 Demography, Census, Vital statistics, Mortality Population dynamics Life expectancy Malawi Sub-Saharan Africa Demography [N01.224] The Karonga Health and Demographic Surveillance System (Karonga HDSS) in northern Malawi currently has a population of more than 35 000 individuals under continuous demographic surveillance since completion of a baseline census (2002-2004). The surveillance system collects data on vital events and migration for individuals and for households. It also provides data on cause-specific mortality obtained by verbal autopsy for all age groups, and estimates rates of disease for specific presentations via linkage to clinical facility data. The Karonga HDSS provides a structure for surveys of socio-economic status, HIV zero-prevalence and incidence, sexual behavior, fertility intentions and a sampling frame for other studies, as well as evaluating the impact of interventions, such as antiretroviral therapy and vaccination programs. Uniquely, it relies on a network of village informants to report vital events and household moves, and furthermore is linked to an archive of biological samples and data from population surveys and other studies dating back three decades. Malawi The Karonga HDSS surrounds the port village of Chilumba, on Lake Malawi, in the southern part of Karonga District . The surveillance area is located between latitudes 10.388 and 10.508S and longitudes 34.088 and 34.278E, covering an area of approximately 135 km2. The lake shore and the Nyika National Park form the boundaries to the east and west, respectively, whereas the boundaries to the north and south are delineated by village boundaries Individual Event history data Monthly recording of births and deaths, continuous recording of opportunistic events and a yearly census to record all demographic events including individual and whole household movements. Yearly The whole population Face-to-face [f2f] The questionnaires are designed to capture the core HDSS information which includes the baseline, birth, inmigration, outmigration and death along with the other questionnaires. NA Data was left censored to 1 Jan 2003 to account for the start-up phase of the surveillance.

Profile: The Karonga health and demographic This paper describes and evaluates the first demographic surveillance system (DSS) in Malawi, covering a rural population of 30,000. Unlike others, the Karonga DSS relies on trained village informants using formatted registers for the primary notification of vital events and migrations. Seven project enumerators subsequently collect detailed data on events notified by the village informants, using stringent identification procedures for households and individuals. Internal movements are traced systematically to augment event registration and data quality. Continuous evaluation of data collection is built into the methods. A re-census conducted after 2 years indicated that the routine system had registered 97% of 1,588 births, 99% of 521 deaths and 92% of 13,168 movements.
