Geographic Information Systems in Public Health

Geographic Information Systems (GIS) in public health are tools that collect, analyze, and visualize spatial data related to health outcomes, environmental factors, and social conditions. By mapping disease patterns, healthcare access, or risk factors, GIS helps public health professionals identify trends, allocate resources effectively, and develop targeted interventions. Essentially, it combines geography with health information to provide a clearer understanding of complex health issues across locations, supporting smarter decision-making to improve community health outcomes.
