The agent is the pathogen, including a virus, bacterium, parasite or other microbes. Exercise 1.8. Therefore, it isnt an adequate model to use for diseases such as cardiovascular disease, cancer, and other diseases that appear to have multiple contributing causes.3, The host is the organism which is exposed to and harbors a disease. (Consider the data sources that would provide the best information or the sources of information that might not be readily available on the Internet. A critical premise of epidemiology is that disease and other health events do not occur randomly in a population, but are more likely to occur in some members of the population than others because of risk factors that may not be distributed randomly in the population. WebExpert Answer An epidemiologic triangle has three components. The best way to understand this model is to look at some examples of how its been used. The triad is used to determine the cause of infectious diseases, non-infectious diseases, and accidents or injuries.
