and dehydration
Epidemiology - ANSWER study of the distribution and
determinants of health-related states or events in specific
populations and the application of this study to control health
problems
Endemic means that a disease - ANSWER Is habitually present

Which of the following is characteristic of a single-exposure,
common-vehicle outbreak? - ANSWER explosive
Which of the following recent widespread disease is considered
pandemic? - ANSWER H1N1 flu virus (swine flu)

disease (etiology)
Study natural history and prognosis
Determine overall size of problem in community (prevalence) or
measure how quickly it is growing in the community (incidence)
Uses of epidemiology - ANSWER Historical use, community
health use, health services use, risk assessment use, and
