correctly answered already passed
Epidemic Investigation - correct answer ✔✔A set of procedures used to identify the cause, i.e.
the infectious agent, responsible for a disease.
Epidemiologic Surveillance - correct answer ✔✔The ongoing and systematic collection, analysis,
and interpretation of health data essential to the planning, implementation, and evaluation of
public health practice, closely integrated with the timely dissemination of these data to those
who need to know. The final link of this chain is the application of these data to prevention and
control.
Notifiable Disease - correct answer ✔✔A disease that the law requires to be reported to public
health authorities as part of the public health surveillance system.
Risk Factor - correct answer ✔✔A characteristic that has been demonstrated statistically to
increase a person's chance of developing a disease or being injured.
Association - correct answer ✔✔The relationship between two or more events or variables.
Case-Control Study - correct answer ✔✔An epidemiologic study that compares individuals
affected by a disease with a comparable group of persons who do not have the disease
("controls") to seek possible causes or associations.
Cases - correct answer ✔✔In a case-control study, people who have the disease being studied.
Cohort Study - correct answer ✔✔A study of a group of people followed over time to see how

and environmental factors, that directly or indirectly influence the frequency or distribution of a
disease.

patient is receiving a drug or a placebo in a clinical trial
Epidemic Curve - correct answer ✔✔A plot of time trends in the occurrence of a disease or
other health-related event for a defined population and time period.
Incidence - correct answer ✔✔A measure of the number of new cases occurring in a population
within a given amount of time, usually a year.
Intervention Study - correct answer ✔✔An epidemiologic study in which the impact of some
intervention on one group of subjects is compared with the effect of a placebo or conventional
therapy on a control group; for example, a clinical trial.
Mortality Rate - correct answer ✔✔The incidence of deaths per unit of time, most often per
year, in a population.
