Epidemiology, the study of factors influencing the spread of communicable disease, has become a broadly discussed topic given the recent Ebola virus outbreak in western Africa. Participants in this session will work in the lab to model epidemiology and examine the results through a simple ELISA assay. We will discuss how to use data to identify original patients. Further, we will look at some in-class activities that highlight some well-established case studies in epidemiology (NGSS ESS3.A and LS2.C).
