Risk
100
The name of a living transport of an agent? (animal;insect; human)
What is a Vector?
100
Immunizations, drivers safety classes, using seat belts, decreasing exposure to the sun
What are examples of primary prevention?
100
Ability to enter and multiply inside a host
What is infectivity?
100
Randomly assigned subjects. Conditions of experiment are under the control of the investigator
What is an experimental study?
100
The probability that an unfavorable event will occur
What is risk?
200
Non-living transport of an agent (clothing;food;milk)
What is vehicle?
200
Pap smears, blood lead level screening, TB tests for hospital employees, occupational disease screening
What are examples of secondary prevention?
200
Ability to produce a clinical reaction after infection
What is pathogenicity?
200
This study begins with the identification of persons with the disease (case) and a suitable comparison group (control)of persons without the disease; then compares the diseased and non-diseased with regard to the frequency of the attribute.
What is a retrospective/case-control study?
200
The rate of occurrence of a condition or disease; the basic rate from which relative and attributable risk are derived.
What is absolute risk/ incidence?
300
Location where the agent can live and thrive (cesspool; animal; human)
What is a reservoir?
300
Disability limitation and rehabilitation
What are tertiary prevention activities?
300
Ability to produce a severe clinical reaction
What is virulence?
300
Hypothesis testing study
What is a retrospective/case control study?
300
The ratio of the incidence of the group with the factor to the incidence of the group without the factor.
What is relative risk?
400
Susceptible human
What is a host?
400
early diagnosis and prompt treatment
What are aspects of secondary prevention?
400
Ability to produce a poisonous reaction
What is toxicity?
400
A study in which subsets of a population (cohort) can be identified as exposed, not exposed, or exposed to varying degrees to factor or factors hypothesized to cause disease. Subjects are then followed over time and frequency of disease is determined.
What is a prospective cohort/ longitudinal study?
400
Measures the amount of risk that can be attributed to one particular factor. Computed by taking the incidence rate of the group with the factor and subtracting the rate for the group without the factor.
What is attributable risk?
500
Biological, physical, and chemical causes of disease
What is an agent?
500
Health promotion and health protection
What are aspects of primary prevention?
500
Ability to produce an immune response?
What is antigenicity?
500
This study tells risk
What is a cohort study?
500
Measures risk (new cases in those at risk)
What is incidence?
