of a disease within a geographic area.

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

excess
of normal expectancy.

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.

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
