Disease Outbreak Tracking
Definition
Disease Outbreak Tracking is a GIS-based method for mapping and analyzing the spread of infectious diseases in space and time. It integrates case data, population information, mobility patterns, and environmental variables to identify hotspots, predict trends, and support health interventions.
Application
Public health officials use GIS to track outbreaks like COVID-19, cholera, or malaria. Dashboards display active cases, vaccination rates, and healthcare access. Heatmaps highlight transmission zones, while movement analysis reveals spread routes. GIS supports contact tracing, risk modeling, and resource deployment. Examples include Johns Hopkins COVID-19 dashboard and WHO health maps.
