Description
The susceptible-infected-recovered (SIR) model in a closed population was proposed by Kermack and McKendrick as a special case of a more general model, and forms the framework of many compartmental models. Susceptible individuals, $S$, are infected by infected individuals, $I$, at a per-capita rate $\beta I$, and infected individuals recover at a per-capita rate $\gamma$ to become recovered individuals, $R$.
