PY - 2022 T2 - Maxcy-Rosenau-Last Public Health & Preventive Medicine, 16e AB - Epidemiology is the basic science and most fundamental practice of public health and preventive medicine. We can study health and disease by observing their effects on individuals, by laboratory investigation of experimental animals, and by measuring their distribution in the population. The epidemiologist uses each of these approached to investigate health and disease in populations. Epidemiology is therefore the scientific foundation for the practice of public health.
