EPIDEMIOLOGY PHC 6001: EXAM 1 REVIEW
QUESTIONS AND ANSWERS 2025-2026
Chapter 1 - CORRECT ANSWER-PUBLIC HEALTH AND EPIDEMIOLOGY
Disease Frequency - CORRECT ANSWER-count cases, records. It quantifies how often
a disease arises in a population. Its calculation involves establishing the disease
definition, counting cases (numerator), and determining the size of the underlying
population (denominator)
Disease Distribution - CORRECT ANSWER-who, what, when, where of the disease. It
refers to the pattern of disease according to the characteristics of person (who is getting
the disease?), place (where it occurs), and time (how is it changing over time?)
A determinant is... - CORRECT ANSWER-a characteristic that influences whether or
not the disease occurs. Determinants of disease can be influenced by the individual,
social surroundings, and environment.
How do we identify the cause of a disease? - CORRECT ANSWER--Is there an
association between EXPOSURE to a risk factor or a personal characteristic and
DEVELOPMENT of disease?
-Is the association causal?
- Descriptive data is important to identifying the causes of disease.
Germ Theory of disease - CORRECT ANSWER-(1850-1900) Specific organisms cause
specific diseases. Resulted from advances in science that allowed viruses and bacteria
to be visualized, isolated, and used to cause disease in healthy animals.
These steps were known as Koch Postulates.
One of the 10 great achievements of public health in the 20th century was: - CORRECT
ANSWER-Inclusion of seat belts in all cars
Epidemiologists are interested in learning about: - CORRECT ANSWER--The frequency
and distribution of diseases
-The causes of disease and ways to control or cure them and
-The causal relationships between diseases
Match the epidemiologist with the work/discovery he is historically known for: -
CORRECT ANSWER-
, Semmelweis - CORRECT ANSWER-Hand hygiene and prevention of Puerperal Fever
Lind - CORRECT ANSWER-Experimental study of diet and scurvy. One of the earliest
experimental studies on treatment of scurvy among sailors.. Consumption of oranges
and lemons was most effective for scurvy tx.
Graunt - CORRECT ANSWER-Published an analysis of the Bills of Mortality- patterns of
mortality and discovered regularity of deaths and births.
Farr - CORRECT ANSWER-Combined data on births, marriages, and deaths with
census data on the population size.
Koch - CORRECT ANSWER-Developed postulates to explain the causes of cholera
and TB
Snow - CORRECT ANSWER-Believed that Cholera was caused by a "germ" spread
through contaminated water.
Shoe leather EPIDEMIOLOGY.
This historic disease theory said that disease was a result of contact with decaying
animal or vegetable matter: - CORRECT ANSWER-Zyme Theory
Public Health - CORRECT ANSWER-PH is a multidisciplinary field whose goal is to
promote the health of populations through organized community efforts.
Epidemiology - CORRECT ANSWER-The study of the distribution and determinants of
disease frequency in human pop's and the application of this study to control health
problems. Disease refers to a broad array of health-related states and events including
diseases, injuries, disabilities, and death.
Chapter 2 - CORRECT ANSWER-MEASURES OF DISEASE FREQUENCY AND
POPULATIONS IN EPIDEMIOLOGY
Population - CORRECT ANSWER-A population is a group of people with a common
characterisitic
What are the main objective of Epidemiology? - CORRECT ANSWER-Is to study the
natural course of disease, to determine the extent of disease in a population, to identify
patterns and trends in disease occurrence, to identify the causes of disease, and to
evaluate the effectiveness of measures that prevent and treat disease.
