Provides an introduction to the formation … WebAccording to the SIR model, the peak of the infection, that is the day when the number of infected people is greatest, is the first day when the proportion of susceptible peoples fall below \(1/R_0\). Equivalently, this suggests the epidemic will peak when the cumulative proportion of the population that has been infected exceeds \(1-1/R_0\).
