Epidemiology - =Science of public health.
Study of disease within populations & risk factors.
Risk factors are genetic, environmental, social, cultural,
or on some direct action by the individual.
Servers to find the "why" of a disease & then to analyse
the disease screening, treatment, prevention, and
monitoring.
-population health - =focuses on risk, data,
demographics, and outcomes
-Outcomes - =End result that follows an intervention
-Aggregate - =defined population
-Community - =Multiple aggregates
-Data - =Compiled information
-Prevalence - =Existence of a disease.
Number of all cases of the disease
-Incidence - =Measures appearance of a disease over a
period of time.
,-Surveillance - =Collection, analysis, and dissemination
of data.
-High-risk - =An increased chance of poor health
outcomes
-Morbidity - =Presence of illness in a population
-Mortality - =Tracking deaths in an aggregate
-Vital statistics - =statistics on live births, deaths, fatal
deaths, marriages and divorces
-Cases - =Criterion used to make decisions whether the
patient has a disease or health event
-Social Justice - =The view that everyone deserves
equal economic, political and social rights and

1) attain high-quality lives preventable disease
2) achieve health equity, eliminate disparities, improve

good health.
4) promote quality of life, healthy development, and
health
-Determinants of Care - =Range of personal, social,
economic, and environmental factors that influence
health status
-Risk Analysis - =Characterization of the potential
adverse health effects of human exposures to
environmental hazards
-health disparities - =Differences of health statuses
between various populations.
-Sensitivity - =Measures the proportion of actual
positives that are correctly identified as such (e.g., % of
sick people who are correctly identified as having the
condition)
-Specificity - =True negative rate
Measures actual negatives that are correctly identified
as such (e.g., % of healthy people who are correctly ID's
as not having the condition)
-Positive Predictive Value (PPV) - =Probability that
subjects with a positive screening test truly have the
disease
-Epidemiological triangle - =Triad with an external
agent, host, and an environment that cause the disease.
