General Principles of Epidemiology
- February 25, 2016
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 infecting organisms, reduce the number of healthcare-associated infections, and protect healthcare providers from infection. Understanding the relationships of host, environment, and organism will aid the infection preventionist in designing studies to determine the cause of healthcare-associated infections and design interventions.
