Epidemiology: The Study of Disease Injury Death in the Community

An epidemic curve depicting a distribution of cases traceable to multiple sources of exposure is a:

• point source epidemic curve.

• propagated epidemic curve.

• case control study.

• descriptive study.

When using criteria of causation, the criterion that addresses the issue of whether the association has been reported in a variety of people, has been exposed in a variety of settings, and can have repeatable results by other researchers is:

• strength.

• specificity.

• temporality.

• consistency.

The number of events that occur in a given population in a given period of time is a:

• rate.

• case.

• pandemic.

• notifiable disease.

Studies that seek to describe the extent of disease in regard to person, time, and place are:

• descriptive studies.

• analytic studies.

• observational studies.

• case/control studies.

A primary care physician is concerned with the course of a disease in an individual, whereas an epidemiologist is concerned with the course of disease in a population.

• True

• False

An unexpectedly large number of cases of an illness, specific health-related behavior, or other health-related event in a particular population is defined as a pandemic.

• True

• False

A disease that lasts 3 months or less is a chronic disease.

• True

• False

An attack rate is an incidence rate calculated for a particular population for a single disease outbreak and is expressed as a percentage.

• True

• False

The average number of years a person from a specific cohort is projected to live from a given point in time is his or her life expectancy.

• True

• False
