Treatment should be initiated early because the disease is more likely to be fatal if treatment is delayed or not given at all. A variety of factors intrinsic to the host, sometimes called risk factors, can influence an individuals exposure, susceptibility, or response to a causative agent. When considering the Epidemiological Triad, there are three main factors that are taken into account: The Agent, The Host, and The Environment. Causes. WebOther portals of entry include the skin (hookworm), mucous membranes (syphilis), and blood (hepatitis B, human immunodeficiency virus).

WebWhen considering the Epidemiological Triad, there are three main factors that are taken into account: The Agent, The Host, and The Environment. To help identify the key risk factors, Sam begins to examine three categories of risk central to epidemiology. The measurement of disease frequency relates to the quantification of disease occurrence in human populations. This variable, having another type of cancer, would be called a(n): An epidemiologist uses the epidemiological triangle to explain the occurrence of disease by looking at the three main components of the model: the host, the environment, and the agent.

Explain. In epidemiology the host is usually a human who gets sick but can also be an animal that acts as a carrier of disease but may or may not present illness. Time can represent the incubation period of a disease (the time between when the host is infected and when symptoms start to present), duration of the illness or amount of time a person can be sick before the disease has run its course and results in death or recovery. If any one of the three factors is missing, the triangle is not complete, no disease will occur. Identify descriptive epidemiological parameters of person, place, and time.
