1. Clinicians focus on an individual’s
health while epidemiologists focus on the public’s health or population
health. How do these differences
affect how clinicians and epidemiologists approach their work?
2. Incidence and prevalence
are two of the basic concepts of epidemiology. In your own words, describe the
difference between them and give an example when you might use each to measure
disease in a population.
3. Explain the concept of herd
immunity and why it is important.
Give an example of where herd immunity may be working or breaking down
in the United States.
4. Epidemiologists often say we need to describe our data in terms of “person,”
“place” and “time.” Give an example
of a disease/ health condition and a population you are interested in. Then, thinking in descriptive epidemiology
terms, if you were studying that issue in your population of interest, what
person, place and time data would you want to collect? What sources of
surveillance data might you use?
