What is epidemiological modeling

This resource provides an overview of epidemiological modeling, covering its key concepts, purposes, and applications in public health and infectious disease research. It describes the main functions of modeling, including explanatory, predictive, and decision-support uses, and introduces major approaches including statistical, geospatial, mechanistic, mathematical, agent-based, economic, and hybrid models. The document also outlines how these methods are used to understand disease dynamics, simulate intervention scenarios, assess impact, and support evidence-based resource allocation.
