,Q1 CRITICALLY EVALUATE EPIDEMIOLOGICAL EVIDENCE AND DESIGN STUDIES TO
INVESTIGATE DISEASE OCCURRENCE IN ANIMAL AND HUMAN POPULATIONS
A veterinary epidemiologist is investigating a cluster of leptospirosis cases in a
community. Which study design is most appropriate to identify risk factors for
sporadic leptospirosis, given that the disease is relatively rare and the population
at risk is not well-defined?
A. Prospective cohort study
B. Case-control study CORRECT
C. Cross-sectional study
D. Randomized controlled trial
RATIONALE: A case-control study is efficient for rare diseases because it starts with cases and
selects controls, allowing assessment of multiple exposures. Prospective cohort studies are
inefficient for rare outcomes, cross-sectional studies assess prevalence not risk factors, and
randomized controlled trials are unethical for observational risk factor identification.
Q2 CRITICALLY EVALUATE EPIDEMIOLOGICAL EVIDENCE AND DESIGN STUDIES TO
INVESTIGATE DISEASE OCCURRENCE IN ANIMAL AND HUMAN POPULATIONS
A new ELISA for detecting Brucella abortus antibodies in cattle has a sensitivity of
95% and specificity of 98%. In a herd with a true prevalence of 2%, what is the
positive predictive value (PPV) of this test, and how would PPV change if the same
test is used in a herd with a prevalence of 20%?
A. PPV at 2% prevalence is 49.2%; it increases to 90.4% at 20% prevalence. CORRECT
B. PPV at 2% prevalence is 95.0%; it remains 95.0% at 20% prevalence.
C. PPV at 2% prevalence is 2.0%; it decreases to 1.0% at 20% prevalence.
D. PPV at 2% prevalence is 49.2%; it decreases to 20.0% at 20% prevalence.
RATIONALE: PPV = (sensitivity × prevalence) / [(sensitivity × prevalence) + ((1 - specificity) × (1 -
prevalence))]. At 2% prevalence, PPV = (0.95×0.02) / (0.019 + 0.0196) = 0.019/0.0386 49.2%.
At 20% prevalence, PPV = (0.95×0.20) / (0.19 + 0.016) = 0.19/0.206 92.2% (closest option A).
PPV increases with prevalence, not constant or decreasing.

,Q3 CRITICALLY EVALUATE EPIDEMIOLOGICAL EVIDENCE AND DESIGN STUDIES TO
INVESTIGATE DISEASE OCCURRENCE IN ANIMAL AND HUMAN POPULATIONS
In a One Health investigation of a novel influenza A virus, which epidemiological
criterion is most critical to confirm efficient human-to-human transmission?
A. Detection of the virus in respiratory samples from index cases
B. A secondary attack rate significantly higher than the primary attack rate CORRECT
C. Phylogenetic similarity to avian influenza viruses
D. Presence of antibodies in animal reservoirs
RATIONALE: Efficient human-to-human transmission is demonstrated by a high secondary attack
rate among close contacts, indicating spread from primary cases. Detection in respiratory
samples or phylogenetic similarity alone does not confirm transmission, and animal reservoir
antibodies are irrelevant.
Q4 CRITICALLY EVALUATE EPIDEMIOLOGICAL EVIDENCE AND DESIGN STUDIES TO
INVESTIGATE DISEASE OCCURRENCE IN ANIMAL AND HUMAN POPULATIONS
A foodborne outbreak is traced to a batch of ground beef. Whole-genome
sequencing (WGS) identifies Escherichia coli O157:H7. Which intervention is most
effective at preventing primary contamination at the processing level?
A. Irradiation of the final product
B. Hazard Analysis and Critical Control Points (HACCP) targeting fecal contamination during
slaughter CORRECT
C. Consumer education on proper cooking temperatures
D. Post-packaging pasteurization
RATIONALE: Primary contamination occurs during slaughter from fecal material. HACCP
controls at slaughter, such as hygienic dressing and carcass washing, prevent initial
contamination. Irradiation and pasteurization are post-contamination interventions, and consumer
education addresses final preparation, not primary contamination.

, Q5 CRITICALLY EVALUATE EPIDEMIOLOGICAL EVIDENCE AND DESIGN STUDIES TO
INVESTIGATE DISEASE OCCURRENCE IN ANIMAL AND HUMAN POPULATIONS
A wildlife biologist is modeling the spread of chronic wasting disease (CWD) in a
deer population. The basic reproduction number (R0) is estimated at 1.8. Which
factor would most likely reduce the effective reproduction number (Re) below 1,
leading to disease fade-out?
A. Increasing the deer population density
B. Culling infected deer at a rate higher than the disease-induced mortality
C. Decreasing the environmental transmission rate by removing contaminated carcasses
CORRECT
D. Introducing a vaccine that reduces susceptibility by 50%
RATIONALE: CWD is transmitted via environmental prion contamination. Removing carcasses
reduces environmental transmission, directly lowering R0. Culling may be counterproductive if it
increases movement, and a 50% effective vaccine would reduce Re by half (0.9) but not below 1
if R0=1.8. Increasing density would increase Re.
Q6 CRITICALLY EVALUATE EPIDEMIOLOGICAL EVIDENCE AND DESIGN STUDIES TO
INVESTIGATE DISEASE OCCURRENCE IN ANIMAL AND HUMAN POPULATIONS
A veterinary public health official is evaluating a new rapid diagnostic test for
rabies in raccoons. The test has a sensitivity of 90% and specificity of 95%. In a
population where 5% of raccoons are truly rabid, what is the probability that a
raccoon testing positive is actually rabid?
A. 48.6% CORRECT
B. 68.4%
C. 90.0%
D. 95.0%
RATIONALE: PPV = (sens × prev) / [(sens × prev) + ((1 - spec) × (1 - prev))] = (0.90×0.05) /
(0.045 + 0.05×0.95) = 0..0925 48.6%. This low PPV due to low prevalence highlights the
need for confirmatory testing.
