Vignettes

Step-by-step conceptual tutorials — from first principles to real-world case studies.

---

The Vignettes section provides accessible, narrative-style explanations of MHASpread concepts. Each vignette is self-contained and builds on the previous one, guiding you from a conceptual introduction through to interpreting simulation outputs and reading published case studies.

Who Should Read What

I am new to disease modeling:
Start with Introduction, then Simulation Outputs.

I want to understand the mathematics:
Read Model Structure and Transmission Processes, then cross-reference the Model section.

I am preparing a simulation run:
Check Data Requirements, then Control Strategies Guide.

I am evaluating policy options:
Start with Control Strategies Guide and Case Studies.
