George Makau answered on 7 Jun 2019:
Epidemiology is the study of how often diseases occur in different groups of people and why. Epidemiological information is used to plan and evaluate strategies to prevent illness and as a guide to the management of patients in whom the disease has already developed.
Alternatively, Epidemiology is the study and analysis of the distribution and determinants of health and disease conditions in defined populations. It is the cornerstone of public health and shapes policy decisions and evidence-based practice by identifying risk factors for disease and targets for preventive healthcare.
