This article describes the most commonly used stochastic epidemic models. For discrete time, the Greenwood and Reed–Frost chain binomials are outlined, with examples. In continuous time, the simple SI, the general SIR and the carrier-borne CSR models are discussed, and Whittle's Threshold Theorem stated. The article concludes with some references to recent literature.
