Disease Frequency - 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 - 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... - 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? - 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 - Answer (1850-1900) Specific organisms cause specific diseases.

What are the main objective of Epidemiology? - Answer Is to study the natural course of
disease, to determine the extent of disease in a population, to identify patterns and trends in
