📈 The Threshold of Transmission: Next-Generation Matrix Multi-Group Modeling 🧮
🧠Conceptual Overview In mathematical epidemiology, the Next-Generation Matrix (NGM) multi-group model represents a rigorous and general framework for quantifying transmission potential in heterogeneous populations. Unlike classical models that assume homogeneous mixing, this approach explicitly accounts for structured interactions among distinct population groups defined by age, occupation, risk behavior, or setting. The core objective of … Read more
