This core function of epidemiology refers to maintaining professional affiliations.

What are linkages?

100

In the epidemiological triangle, this is known as the carrier of the disease.

What is a host?

100

This term is used to relate screening and disease by noting the ability of a test to detect a "true positive."

What is sensitivity?

100

This epidemiological study is often written by a clinician to represent an analysis of one individual with a particular presentation, medical issue, or set of signs and symptoms.

What is a case report?

100

This measure refers to the number of people who died from all causes during a certain time period, divided by the total population.

What is crude mortality rate?

200

This core function of epidemiology refers to the ongoing collection and interpretation of data.

What is analysis/surveillance?

200

In the epidemiological triangle, this is known as the surroundings of the host.

What is the environment?

200

This term is used to related screening and disease by noting the ability of a test to detect a "true negative."

What is specificity?

200

This epidemiological study is observational and usually involves information on diseases and health behaviors being collected on a population simultaneously.  

What is a cross-sectional study?

200

This measure refers to the number of deaths from a specific cause over a period of time, divided by the total population.

What is cause-specific mortality rate?

300
This agency is responsible for implementing surveillance of epidemiology in the United States.

What is the Centers for Disease Control and Prevention (CDC)?

300

In the Natural History of Disease model, this stage is before exposure to an agent.

What is the stage of susceptibility?

300

Per the 2x2 Table, if the individual is positive on the screening test and positive for the disease, this is called....

What is a true positive?

300

This epidemiological study is an observational study of a large population that is followed over time.

What is a cohort study?

300

This measure is defined as the number of people (both new and existing cases) who have a disease over a specific amount of time.

What is the prevalence?

400

This core function of epidemiology refers to determining the effectiveness of an intervention.

What is evaluation?

400

In the Natural History of Disease model, this stage is when pathological changes have begun but have not evolved into an onset of symptoms.

What is the stage of subclinical disease?

400

Per the 2x2 Table, if the individual is positive on the screening test and negative for the disease, this is called...

What is a false positive?

400

This epidemiological study type is similar to a randomized controlled trial (RCT) but does not randomize participants.

What is a quasi-experimental study?

400

This measure refers to the number of new cases over a specific amount of time but only take into account those at-risk.

What is the incidence?

500

This type of assessment is conducted throughout the planning and implementation process.

What is formative assessment?

500

In the Natural History of Disease model, this stage begins at the onset of symptoms and captures the usual time of diagnosis.

What is the stage of clinical disease?

500

Per the 2x2 Table, if the individual is negative for the screening test and positive for the disease, this is called....

What is a false negative?

500

This epidemiological study is the gold standard for determining the effectiveness of a treatment or intervention due to its experimental and randomized basis. 

What is a randomized controlled trial (RCT)?

500

This measure is defined as the number of people that contracted the illness divided by the number of people exposed to the suspected agent.

What is the attack rate?
