This note lays out the basic SIR epidemiological model of contagion, with a target audience of economists who want a framework for understanding the effects of social distancing and containment policies on the evolution of contagion and interactions with the economy. The model is calibrated to the most recent data, however it simple nature abstracts from many important considerations and its output is not intended to supersede estimates from more sophisticated epidemiological models.
