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.
