Geographical Information Systems in Public Health

Geographical Information Systems (GIS) in public health are tools that combine data and maps to analyze health trends and patterns related to specific locations. By visualizing information—like disease outbreaks, access to healthcare, or environmental hazards—GIS helps public health officials identify at-risk populations, allocate resources effectively, and develop targeted interventions. This spatial analysis supports better decision-making, ultimately improving health outcomes in communities by understanding how geography affects health.
