WebDec 9, 2024 · The SIR model separates the population into three compartments: the susceptible (S), infected (I), and removed (R) compartments. The susceptible compartment is comprised of individuals that are healthy but can contract the disease. The infected compartment is comprised of individuals who have already contracted the disease.

WebSIR is an e ective model for epidemic spread under certain assumptions. orF example, we assume that the network is what's called "fully mixed". This implies that no group of members of a network are more likely to encounter each other than any other group.
