• aggregate. CORRECT ANSWER: is a defined population.
• community. CORRECT ANSWER: is composed of multiple aggregates
• data. CORRECT ANSWER: is complied information
• Prevalence. CORRECT ANSWER: measures the existence of a disease.
Measures the number of all cases of a disease or attribute in a population at a given
time
• Incidence. CORRECT ANSWER: measures the appearance of a disease.
Measures the occurrence of new events in a population over a period of time.
• surveillance. CORRECT ANSWER: is the collection, analysis, and dissemination
of data.
,• high-risk. CORRECT ANSWER: is an increased chance of poor health outcome.
• Morbidity. CORRECT ANSWER: is the presence of illness in a population
• mortality. CORRECT ANSWER: is related to the tracking deaths in an aggregate
• vital statistics. CORRECT ANSWER: statistics on live births, deaths, fetal
deaths, marriages and divorces.
• cases. CORRECT ANSWER: set of criteria used in making a decision as to
whether an individual has a disease or health event of interest
• Social Justice. CORRECT ANSWER: the view that everyone deserves equal

• Inter-professional collaboration. CORRECT ANSWER: The idea of sharing and

the proportion of actual negatives that are correctly identified as such (e.g., the
percentage of healthy people who are correctly identified as not having the
condition)
• Positive predictive value. CORRECT ANSWER: is the probability that subjects
with a positive screening test truly have the disease
• epidemiological triangle. CORRECT ANSWER: 1. A traditional model of
infectious disease causation, known as the Epidemiologic Triad is depicted in
Figure 2. The triad consists of an external agent, a host and an environment in
which host and agent are brought together, causing the disease to occur in the host.
