Epidemiology is the study of factors determining disease in a population. It is also defined as the study of the distribution and determinants of disease and other conditions in populations before, during and after preventive and other interventions. It is population-based and describes health-related phenomena through measurements of disease and its determinants and distribution in a given population.
