Definition

A compartmental epidemiological model that partitions a population into Susceptible (S), Exposed (E, infected but not yet infectious), Infectious (I), and Recovered (R) compartments and represents transitions between them by rates or probabilities to describe transmission dynamics when a latent (non‑infectious) period separates infection from infectiousness.
