|
Definition
Primary Prevention
- intervention occurs before onset of disease

herd immunity
- 3 qualifiers |
|
Definition
aka community immunity
the resistance of a group to disease associated with large proportion of non-susceptibles.
but, if many individuals resistant ENTIRE population likely protected.
qualifiers:
1. infectious agent needs to be restricted to ONE host species, and transmission relatively direct
2. infection must induce solid immunity
3. need random mixing of individuals. *degree of random mixing dictates degree of herd immunity |

|
Term
|
Definition
describes outcome (the what) relative to the who, where, when (FREQUENCY AND DISTRIBUTION) to help understand the why.
information about occurrence of disease but with NO attempt to establish association between cause and effect |

|
Term
|
Definition
investigates reasons for disease/death/events/productivity (the why) relative to the what, who, where, when.
examines the DETERMINANTS to ultimately prevent and control health problems.
uses stats to ESTABLISH RELATIONSHIPS between causative factors and occurrence of disease |

|
Term
| list and describe the two types of epi research designs |
|
Definition
1. Descriptive
-only describes
-no formal comparison made between groups of subjects
-good for hypoth. generation
2. analytic/explanatory
-used to make inferences about relationships between exposures and outcomes
-comparisons made |
