Epidemiology is about how diseases occur and spread in groups of people. It focuses on patterns of disease across populations—who gets sick, where it happens, and when it occurs—and seeks to understand the factors that influence risk, such as exposures, behaviors, environment, genetics, and social conditions. By measuring incidence and prevalence and comparing different groups, epidemiology identifies determinants that can be targeted to prevent illness and control outbreaks. This population-level focus on distribution and causes is what sets it apart from pursuing individual clinical care, lab culture techniques, or nutritional analysis, which are more about treating a person, identifying microbes, or studying diet, respectively.
