Explains the important concept of Basic Reproduction Number (R0, R-nought), provides mathematical justification for the definition of R0 as the Dominant Eigenvalue of the Next Generation Matrix, and shows how it generalises across a range of different disease transmission structures. Also provides examples of the Next Generation Matrix, and the associated R0 (dominant eigenvalue) for Vector-Host disease (malaria), SIR model, and multi-group SEIR model.
