Question 1
Which epidemiologic measure describes the occurrence of new cases of
disease in a population during a specified period?
A. Prevalence
B. Incidence
C. Case-fatality rate
D. Proportional mortality
Answer: B. Incidence
Rationale: Incidence measures the occurrence of new disease events over
a specified period among a population at risk. Prevalence, in contrast,
includes existing cases and reflects the overall burden of disease at a
point or during a period.
Question 2
In a cohort study, the primary measure used to compare disease
occurrence between exposed and unexposed groups is:
,A. Odds ratio
B. Relative risk
C. Predictive value
D. Population attributable fraction
Answer: B. Relative risk
Rationale: Relative risk compares the incidence of disease among
exposed individuals with the incidence among unexposed individuals. It
is particularly appropriate for cohort studies in which incidence can be
directly calculated.
Question 3
Which measure is most appropriate for describing the proportion of
animals with a disease at a specific point in time?
A. Point prevalence
B. Incidence density
C. Relative risk
D. Attack rate
Answer: A. Point prevalence
Rationale: Point prevalence represents the proportion of a population
affected by a disease at a particular point in time. It includes existing
cases regardless of when they developed.
Question 4
,A diagnostic test has high sensitivity. Which statement is most
accurate?
A. A negative result helps rule out disease
B. A positive result always confirms disease
C. The test has few false positives
D. The test has high specificity
Answer: A. A negative result helps rule out disease
Rationale: Highly sensitive tests detect most truly diseased animals and
therefore produce few false-negative results. Consequently, a negative
result on a highly sensitive test can be useful for ruling out disease,
particularly when disease prevalence and other factors are appropriate.
Question 5
Which characteristic of a diagnostic test refers to its ability to correctly
identify animals that do not have the disease?
A. Sensitivity
B. Specificity
C. Repeatability
D. Accuracy
Answer: B. Specificity
Rationale: Specificity is the proportion of truly disease-free individuals
who test negative. A highly specific test produces relatively few false-
positive results.
, Question 6
A disease has a basic reproduction number (R₀) greater than 1 in a
susceptible population. What does this generally indicate?
A. The disease cannot spread
B. Each infected individual produces less than one secondary infection
C. Sustained transmission is potentially possible
D. The disease has already been eliminated
Answer: C. Sustained transmission is potentially possible
Rationale: An R₀ greater than 1 means that, under the specified
conditions and in a fully susceptible population, each infected individual
produces more than one new infection on average. This permits
continued transmission.
Question 7
Which type of bias occurs when study participants are selected in a
manner that results in systematic differences between the study sample
and the population of interest?
A. Selection bias
B. Recall bias
C. Observer bias
D. Measurement bias
Answer: A. Selection bias
