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-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.","time_periods":[{"start":"2003-01-01","end":"2011-12-31","cycle":""}],"coll_dates":[{"start":"2003-01-01","end":"2015-12-31","cycle":"Release coverage"}],"nation":[{"name":"Malawi","abbreviation":"MWI"}],"geog_coverage":"The Karonga HDSS surrounds the port village of Chilumba, on Lake Malawi, in the southern part of Karonga District .
