Q

TRUE OR FALSE

✓ Disease results from an imbalance between the disease agent and man as the host
✓ Nature and extent of imbalance depends upon nature and characteristics of agent and
host
✓ The characteristics of agent and host and their interactions are directly related to and
largely dependent on the nature of environment

Q

The Epidemiologic Triangle consists of three component:

A

Host
Agent
Environment

30
Q

This is a component of environment that is composed of the inanimate surrounding such as the
geophysical condition of the climate.

A

Physical environment

31
Q

This is a component of environment that makes up the living things around us such as plants and
animal life.

A

biological environment

32
Q

this is a component of environment which may be in the form of level of economic development of the community, presence of social disruptions and the like.

A

Socio-economic environment

33
Q

What are the 3 components of environment?

A

Physical, Biological, Socio-economic environment

34
Q

This model implies that each must be analyzed and understood for comprehensions and prediction of patterns of a disease.

A

Epidemiologic Triangle

35
Q

This model refers to change in any of the component will alter an existing equilibrium to increase or decrease the frequency of the disease.
