In this lecture, we apply system dynamics modeling to generate basic models of disease spread and scenario planning for intervention strategies in epidemiology and public health. In particular, we introduce the SIR model (and a few variations on it) and discuss the details of how it works and what the behavior over time curves mean. Topics related to current events, such as Ebola, COVID-19, and "flattening the curve", are discussed in relation to these models.
