- Control (as in controlling health problems)
- Incubation Period
- Subclinical Infection
- Quarantine and Isolation
- Populations—One of the most important distinguishing characteristics of epidemiology is that it deals with groups of people rather than with individual patients.
- Control—Although epidemiology can be used simply as an analytical tool for studying diseases and their determinants, it serves a more active role. Epidemiological data steers public health decision making and aids in developing and evaluating interventions to control and prevent health problems. This is the primary function of applied, or field, epidemiology.
Controlling and Preventing Information System Disease in Populations of Technological Objects
Wait, can information systems really be diseased? I believe they can, and that all too many of them are.
Definition: Information System Disease
"an incorrectly functioning or incomplete component, feature, sub-system, or unit of a an information system resulting from the effect of requirements, design, or developmental errors and defects, performance, usability, or capability deficiency, or unfavorable environmental factors such as network communications failures or operating system incompatibilities."Aside: With the increasing use of biotechnology and nanotechnology that interacts with our own biology, it will become increasing difficult to draw any clear distinctions between a designed technologically-augmented biological system and one that is strictly naturally evolved.
- the social and economic environment,
- the physical environment, and
- the person's individual characteristics and behaviors.
The Determinants of Information System Health are Almost Always Human-Caused
Incidence refers to the occurrence of new cases of disease or injury in a population over a specified period of time
Prevalence, sometimes referred to as prevalence rate, is the proportion of persons in a population who have a particular disease or attribute at a specified point in time or over a specified period of time. Prevalence differs from incidence in that prevalence includes all cases, both new and preexisting, in the population at the specified time, whereas incidence is limited to new cases only.
