WebIf we combine the last two avriations we made on the SIR model we come to this formulation, which is an SIRS model. This SIRS model allows the transfer of individuals … Webthe expected duration of infection. But how do we know that this quantity defines the epidemic threshold of a particular infection? To understand this, we need to formulate an epidemic model. The model we use is called an SIR model, where SIR stands for “Susceptible-Infected-Removed.” For simplicity, we will deploy several assumptions: 1.
