purpose of this assignment is to identify key concepts in epidemiology that
will assist the student in understanding the purpose of epidemiology as it
relates to clinical practice, surveillance and prevention of disease, and
healthcare research.You will work on building a foundation of definitions and
an understanding of how they apply to monitoring disease in populations.
this assignment, the student will demonstrate the ability to:
key terms in epidemiology, community health, and population-based research.
Due Date:Sunday 11:59 p.m. (MT) at the end of Week 1

each question identify the correct answer and cite the source used to answer
Prior to completing this worksheet, review the Week
1 lecture and reading assignments (Chapters 1-4 of your course text). Provide a
complete answer to each question. Each
question is worth 5 points. Please cite the source of each answer below the
answer as in the example provided below.

1. Define Primary, Secondary, and Tertiary prevention.
Primary prevention is the
prevention of the development of disease. Secondary prevention is detecting
disease early to help reduce complications while, tertiary prevention is the
reduction of the impact of the disease (Gordis, 2014).
2. True or False:
Prevention and treatment of a single specific disease are exclusive
activities that do not occur together when providing care to a patient.
3. The ________________ Concept is important because in
counting incidence and prevalence of disease it is not sufficient to count only
clinically apparent cases, but those who are asymptomatic or exposed without

___D_ Pandemic A. Habitual presence
of a disease within a geographic area.
__A__ Endemic B. Occurrence
of a disease in a community/geographic area in
of normal expectancy.
___E_ Common-Vehicle Exposure C. Resistance of a group of people to a
disease because a large
of the population is immune.
__B__ Epidemic D.
An excessive occurrence of disease present globally.
__C__ Herd Immunity E. When a group of people are exposed to a
substance or organism that causes common illness.

A. Define, through
a fractional representation, what attack rate is.
B. After a large

Using the following 2 by 2 table, numerically represent the attack rate for wedding attendies who ate

and define at least two measures of mortality as fractional representations.
