DISCUSSION BOARD DUE THURSDAY 250-350 WORDS. THE EPIDEMIOLOGIC EXAMPLE IS IN THE ATTACHMENT. THE NAME IF THE BOOK IS (EPIDEMIOLOGY FOR PUBLIC HEALTH - PRACTICE 5TH 14 BY ROBERT H FRIIS.
The following is an example of an epidemiologic triad.
Agent: the salmonella organism
Keep in mind that agents can be biologic (e.g., bacteria or viruses), chemical (e.g., poisons or alcohol), physical (e.g., trauma or radiation), or nutritional (e.g., a lack or excess of essential nutrients).
Host factors: individuals who are particularly vulnerable (e.g., the very young or very old and immunocompromised individuals)
Note that, in general, host characteristics can include age, sex, race, religion, customs, occupation, genetic factors, other health factors, and immunologic status.
Environmental factors: contaminated kitchen surfaces or utensils, undercooking of contaminated food items, or contaminated chicken
Environmental factors can include temperature, crowding, noise, pollution, food, and radiation.
Changes in one factor in the epidemiological triad can influence the occurrence of disease by increasing or decreasing a person's risk for disease. Consider how variations in each factor shown in the example can influence the manifestation of disease. Refer to pages 438–445 in your textbook for further explanation.
In this Discussion, you will provide other examples of the epidemiological triad and discuss them with your colleagues.
To prepare
for this Discussion:
Select one agent of an infectious disease. Select an agent of interest or an agent listed on the CDC's website at
http://wwwn.cdc.gov/nndss/script/conditionlist.aspx?type=0&yr=2013
Consider how the health condition applies to the epidemiologic triad (also known as the epidemiologic triangle).
To complete
the Discussion,
post
the name of the disease you selected. Next, apply the disease to the epidemiologic triad. Provide an example of an agent that is associated with the disease you selected. Provide at least three examples of environmental factors and three examples of host factors that contribute to the likelihood of transmission of that agent to an individual.

Chapter 12, "Epidemiology of Infectious Diseases"This chapter
explores the modes of transmission of infectious agents. In
addition, the categories of infectious disease agents and their
characteristics are presented. Aspects of investigating disease
outbreaks are also explained.
What is Epidemiology?
This presentation provides a general overview of the field of
epidemiology. It also serves as a summary of the topics that will
be presented in this course.
