WebEpidemiology . Description: Identify descriptive epidemiological parameters of person, place, and time. Because the agent-host-environment model did not work well for many non-infectious diseases, several other models that attempt to account for the multifactorial nature of causation have been proposed. Development of appropriate, practical, and effective public health measures to control or prevent disease usually requires assessment of all three components and their interactions.

Between the vertices, scientists will often describe the center of the triangle as representing time. An identification system that identifies employees, volunteers, physicians, students, and regularly scheduled contract services staff as authorized personnel of the health care facility should be established. The agent infects the host, which is the organism that carries the disease. Explain how it will determine if a case is confirmed, probable, or possible. (42) This model is illustrated in Figure 1.17.

When considering infectious diseases, the agent is an external microorganism that needs to be present in order for the disease to occur. The PHN understands that the agent could be one of many types except: John has just taken a job as a PHN at the local public health department in a high-income county adjacent to a large metropolitan area. But because lung cancer can develop in persons who have never been exposed to either smoking or asbestos, a proper model for lung cancer would have to show at least one more Sufficient Cause Pie that does not include either component B or component C.
