Choropleth maps are a powerful tool in epidemiology for several reasons: - Visual Clarity: They provide a clear and intuitive way to communicate complex data, making it easier for policymakers, researchers, and the public to understand spatial patterns. - Identification of Hotspots: These maps help in identifying areas with high disease burden, which can be critical for resource allocation and targeted interventions. - Trend Analysis: By comparing maps over time, epidemiologists can track the progression of diseases and evaluate the impact of public health interventions.
