Y1 - 2005 N1 - T2 - Medical Epidemiology, 4e AB - A variety of measures are employed in epidemiology, each of which has a specific definition and use. When characterizing the likelihood of developing a disease within a specified period of time, the appropriate measure is risk. Prevalence is used to describe the proportion of a population that is affected by a disease. When measuring the rate of new occurrences of a disease, incidence is the appropriate measure. Case fatality is used to describe the natural history of a disease and corresponds to the proportion of affected persons who die from that illness. Conversely, survival is the likelihood of escaping death from that illness.
