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 infection.

4. Please define the following:

Clinical Disease –

Preclinical Disease –

Subclinical Disease –

Persistent (Chronic) Disease –

Latent Disease –

5. Match the following terms with their
definition:

____ Pandemic A. Habitual presence of a
disease within a geographic area.

____ Endemic B. Occurrence of a disease in a
community/geographic area in

excess of normal expectancy.

a group of people to a disease because a large

portion of the population is immune.

____ Epidemic D. An excessive occurrence of
disease present globally.

____ Herd Immunity E. When a group of people
are exposed to a substance or organism that causes common illness.

associated with the Black Death in Europe in the late 1300’s?

7. This is a two part question:

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

Epidemiological
Formulas and Statistics

Parameter	Definition	Formula
Incidence (exposed)	Incidence of new cases of disease in persons who were exposed	number (exposed with disease)/Total number of exposed
Incidence (unexposed)	Incidence of new cases of disease in persons who were not exposed	number (unexposed with disease)/Total number of unexposed
Incidence of Disease	Measure of risk. Total number in a population with a disease divided by the total number of the population.	Number with the disease/ Total population number
Relative Risk	Risk of disease in one group versus another. Risk of developing a disease after exposure. If this number is one, it means there is no risk. R(exposed)/Risk (unexposed)	(# exposed with disease(divided by)/total of all exposed) (# of non-exposed with disease/(divided by)total of all non exposed)
Odds Ratio	A measure of exposure and disease outcome commonly used in case control studies.	R(exposed)/ R (unexposed) 1- R(exposed) 1-R(unexposed)
Prevalence	The number of cases of a disease in a given time regardless of when it began. (new and old cases)	(Persons with the disease/ Total population) X 1000
Attributable Risk	The difference in disease in those exposed and unexposed and is calculated from prospective data. Directly attributed to exposure (if exposure gone, disease would be gone)	R(exposed) – R(unexposed)
Crude Birth Rate	The number of live births per 1,000 people in the population	(# of births/estimated mid-year population) X 1000
Crude Death Rate	The number of deaths per 1,000 people in the population	(# of deaths/estimated mid-year population) X 1000
Fetal Death Rate	The number of fetal deaths (20 weeks or more gestation) per 1,000 live births.	(# of fetal deaths/ # of live births + fetal deaths) X 1000
Annual Mortality Rate	Usually an expression of a specific disease or can be all causes per 1,000 people for a year.	(# of deaths of all causes (or a specific disease)/Mid-year population) X 1000
Case Fatality Rate	The parentage of individuals who have a specific disease and die within a specific time after diagnosis.	(# of persons dying from a disease after diagnosis or set period/ # of persons with the disease) X 100

malaria?

given population = 120

Total number of people with lung cancer who
smoked = 90

Total number of people with lung cancer who
did not smoke = 30

Total number of people who smoked = 150

Fill in the missing parameters based on the
above.

Requirements

This paper should clearly and comprehensively
identify the disease or population health problem chosen. The problem must be
an issue in your geographic area and a concern for the population you will
serve upon graduation with your degree. The paper should be organized into the
following sections:

1. Introduction with a clear presentation of
the problem as well as significance and a scholarly overview of the paper.

2. Background of the disease including
definition, description, signs and symptoms, and current incidence and/or
prevalence statistics current state, local, and national statistics pertaining
to the disease. (Include a table of incidence or prevalence rates by your
geographic county, state, and national statistics.)

3. A review of current surveillance methods
and any mandated reporting or methods for reporting the disease for providers.

4. Conduct descriptive epidemiology analysis
of the disease including who is more frequently affected and characteristics of
the population that might help in creating a prevention plan. Include costs
(both financial and social) associated with the disease or problem.

5. Review how the disease is diagnosed,
current national standards for screening or prevention, and pick one screening
test and review its sensitivity, specificity, positive predictive value, cost
and any current national guidelines for conducting which patients to conduct
this test on.

6. Provide a brief plan of how you will
address this epidemiological disease in your practice once you are finished
with school. Provide three actions you will take along with how you will
measure outcomes of your actions.
