well as behaviors and environmental exposures.

Answer 9

Personal characteristics

Question 10

Question 20

TWO MAIN AREAS OF INVESTIGATION

Answer 20

1. Describes the distribution of health status in terms of age, gender, race, geography and time
2. Patterns of disease distribution in terms of causal factor.

Question 21

In epidemiology of any disease or event, one studies the factor which contribute to its causation and behavior –

Answer 21

AGENT, HOST, ENVIRONMENT

Question 22

Epidemiologic concept maintains that there

Answer 22

can be no single cause of disease

Question 23

THE AGENT FACTORS OF DISEASE

Answer 23

 Age
 Sex
 Race
 Habits, customs and religion
 Exposure to agent
 Defense mechanism of the host

Question 24

This could be living or non-living, physical or mechanical in nature such as extremes of temperature, light, electricity

Answer 24

AGENT

Question 25

They could be chemicals – endogenous (within the body) or exogenous (poison)

Answer 25

AGENT

Question 26

Association:

Answer 26

Is a specified health outcome more likely in people with a particular “exposure”?

Is there a link? Association is a statistical relationship between two variables.

Question 27

the traditional model for

infectious disease.

Answer 27

epidemiologic triad or triangle

Question 28

consists of an external agent, a susceptible host, and an environment that brings the
host and agent together. In this model, disease results from the interaction between the agent
and the susceptible host in an environment that supports transmission of the agent from a
source to that host.

Answer 28

epidemiologic triad or triangle
