Lilienfeld and Lilienfeld have defined epidemiology as “the study of the distribution of a disease or physiological condition in human populations and of the factors that influence this distribution.” Epidemiology is an eclectic discipline, utilizing statistics, sociology, and biology of the study of disease populations.
