Epidemiology is a difficult but an important subject in public health curriculum. As teachers, we need to be very innovative in teaching the core concepts in epidemiology since it is basically a research oriented subject that calls for enormous application of logic and mathematical skills. Very often, complex epidemiological concepts need to be communicated in simple language with the help of analogies and examples. Here is a case study on how a complicated concepts of "Epidemic" which is very often (mis)understood only in the context of infectious diseases and the concept of causal associations were communicated to Public Health students in a novel way to facilitate better learning. This method of pedagogical approach promotes critical and analytical thinking which is crucial in internalizing and applying concepts in epidemiology.
