Epi is a term used to refer to epidemiology, the study of the prevalence and spread of disease in a population. It's particularly important in public health, as it helps to identify which diseases are more likely to occur in a given population, and why. Recent progress in this area has been driven by data science and predictive modelling, which have enabled health practitioners to better understand the patterns and risk associated with specific diseases. Epi also involves intervention strategies, including vaccinations, health promotion and public health policies, that work to reduce the spread of infectious diseases among a population.
