Main goal of the science of epidemiology Ans: — prevent and
control disease unlike the secondary and tertiary approaches
found in traditional western medicine
Epidemiology Ans: — study of the distribution and determinants
of health-related states or events and application of this study to
control diseases/other health problems (ex. infant mortality)
-various methods can be used to carry out epidemiological
investigations
-surveillance and descriptive studies used to study distribution;
analytical studies used to study determinants
Two streams Ans: — 1. Exposure-oriented sub-disciplienes (ex.
nutritional, social, environmental)
2. Disease-oriented sub-disciplines (ex. cancer, injury, perinatal)
Other streams of epidemiology Ans: — -occupational epidemiology
-molecular epidemiology
The most well-known type of epidemiology Ans: — public health
6 Basic Building Blocks of Epidemiology Ans: — 1. Epidemiologic
model
2. Concept of susceptibility
3. Modes of transmission
4. Natural Hx/progression of disease
5. Association and Causation

6. Web of causation
Epidemiologic Triad Ans: — Agent-Host-Environmental Model
-traditional view of health and disease
-theory behind model: disease results from interaction among
these 3 elements
-any change in one of the 3 sides (agent, host, environment) will
result in disequilibrium
Host Ans: — human being in which disease occurs
Agent Ans: — contagious or non-contagious force that begins or
prolongs health problem (ex. bacteria, viruses, stimuli such as
smoking)
Environment Ans: — promotes exposure of host to agent
Epidemiological Model Ans: — -Vector
-Person
-Place
-Time
Vector Ans: — another factor (ex. deer tick assists movement of
Lyme disease)
Person Ans: — age differences, sex, ethnicity, ed. level, dietary
practices
Place Ans: — variations b/w regions, countries, continents,
population density, rural/urban, etc.
Time Ans: — seasonal variations, health challenges after specific
event (ex. PPD after birth of baby)
Susceptibility Ans: — -individual characteristic determien risk or
degree of susceptibility of each person to a certain agent
-AKA vulnerability, which determines host response
