Epidemiology—the study of the frequency, distribution, cause, and control of disease in populations—forms the basis of all health-related studies. It provides the background for interventions to reduce transmission of infectious organisms, reduce the number of healthcare-associated infections, and protect healthcare personnel from infection. Understanding the relationships of host, environment, and organism will aid the infection preventionist in designing studies to determine the causes of healthcare-associated infections and design and evaluate interventions.
