1What is the BEST definition of incidence?

A.Total number of existing cases at a point in time

B.Number of NEW cases arising in a defined population over a specified time period

C.Number of deaths from a disease per total population

D.Proportion of diseased animals detected on necropsy

Explanation: Incidence measures NEW cases per population at risk per unit time (incidence rate or cumulative incidence/risk). Prevalence measures EXISTING cases (new + old) at a point or period. Incidence reflects the force of disease occurrence and is the correct measure for studying causation; prevalence is influenced by both incidence and duration.

2The relationship Prevalence ≈ Incidence × Duration holds best when which condition is met?

A.Disease has very high case-fatality

B.Disease is steady-state (incidence and duration are stable) and prevalence is low

C.Population is rapidly growing

D.Exposure is very rare

Explanation: The P ≈ I × D approximation assumes a steady-state population with stable incidence and average duration, and low prevalence (so that the pool at risk approximates the total population). A disease that is long-lasting but rarely fatal (e.g., heartworm in untreated dogs) will accumulate high prevalence.

3Case-fatality rate (CFR) is calculated as:

A.Deaths from disease / total population

B.Deaths from disease / diseased individuals

C.Deaths from all causes / total population

D.New cases / population at risk

Explanation: Case-fatality rate is the proportion of individuals with the disease who die from it (deaths / cases). It measures disease severity/virulence. Mortality rate uses the total population in the denominator and is a measure of population burden, not severity.

4In a case-control study of canine lymphoma and herbicide exposure, the odds ratio (OR) is 3.2 (95% CI 1.8-5.7). The BEST interpretation is:

A.Exposed dogs have 3.2 times the risk of developing lymphoma

B.Odds of prior herbicide exposure are 3.2 times higher among lymphoma cases than controls; association is statistically significant

C.32% of lymphomas are caused by herbicides

D.The association is not statistically significant because the CI includes 3

Explanation: Case-control studies yield an OR (comparing odds of exposure in cases vs. controls). With a rare outcome the OR approximates RR, but the direct interpretation is in odds. Because the 95% CI excludes 1.0, the result is statistically significant at α = 0.05.

5Which study design is BEST suited to investigate a rare disease with a long latency period?

A.Cross-sectional survey

B.Prospective cohort study

C.Case-control study

D.Randomized controlled trial

Explanation: Case-control designs are efficient for rare diseases because cases are sampled directly; a cohort study would require following a huge population for years. Cohorts are better for rare exposures. RCTs are impractical for causes you cannot ethically assign.

6In a cohort study, the risk ratio (RR) for mastitis in cows housed on sand bedding vs. sawdust is 0.55. This indicates:

A.Sand bedding increases mastitis risk by 55%

B.Sand bedding reduces mastitis risk by 45% compared to sawdust

C.No association

D.55 additional cases per 100 cows on sand

Explanation: RR = 0.55 means the risk on sand is 55% of the risk on sawdust, i.e., a 45% relative risk reduction. RR < 1 indicates a protective association; RR > 1 indicates increased risk; RR = 1 indicates no association.

7Berkson bias is a form of which type of bias?

A.Recall bias

B.Selection bias (specifically from using hospitalized controls)

C.Interviewer bias

D.Publication bias

Explanation: Berkson's bias arises when hospital-based cases and hospital-based controls have different probabilities of admission for their conditions, producing spurious associations. It is a classic form of selection bias in case-control studies using hospital controls.

8Recall bias is MOST problematic in which study design?

A.Prospective cohort

B.Retrospective case-control

C.Randomized controlled trial

D.Ecologic study

Explanation: In retrospective case-control studies, owners of affected animals often recall exposures more thoroughly than owners of controls — a differential misclassification that biases the OR. Prospective designs collect exposure data before outcome, minimizing recall effects.

9A variable must satisfy which set of conditions to act as a confounder?

A.Be rare and unmeasured

B.Be associated with the exposure, be an independent risk factor for the outcome, and NOT be on the causal pathway

C.Be caused by the exposure and modify the outcome

D.Be a mediator between exposure and outcome

Explanation: A confounder (1) is associated with the exposure, (2) is an independent risk factor for the outcome, and (3) is not an intermediate on the causal pathway. Controlling confounding is done via study design (randomization, matching, restriction) or analysis (stratification, regression).

10The attributable risk percent (AR%) in the exposed group represents:

A.The absolute baseline risk in the unexposed

B.The fraction of risk in the exposed group attributable to the exposure

C.The prevalence of exposure in cases

D.The number needed to treat

Explanation: AR% = (Risk_exposed − Risk_unexposed) / Risk_exposed × 100 = (RR − 1)/RR × 100. It estimates the proportion of disease in exposed animals that would be eliminated if the exposure were removed, assuming causality.

ACVPM Veterinary Preventive Medicine Study Tips from Top Performers

1Bayes' theorem and predictive values — highest-yield biostatistics. PPV = (Se × prev) / [(Se × prev) + ((1-Sp) × (1-prev))]. Remember: at low prevalence, even high-Sp tests have poor PPV (many false positives among true negatives). Screening tests prioritize sensitivity (rule-out, SnNout); confirmatory tests prioritize specificity (rule-in, SpPin). Likelihood ratios are prevalence-independent: LR+ = Se/(1-Sp), LR- = (1-Se)/Sp.

2Rabies post-exposure prophylaxis (PEP) — memorize ACIP/WHO: previously unvaccinated exposed person gets wound washing, human rabies immune globulin (HRIG) 20 IU/kg infiltrated around wound, and 4-dose HDCV/PCECV vaccine series on days 0, 3, 7, 14 (add day 28 if immunocompromised). Previously vaccinated: 2 doses on days 0 and 3, NO HRIG. Bats — consider PEP even without documented bite if bat in room with sleeping/incapacitated person.

3HACCP 7 principles in order: (1) Conduct hazard analysis, (2) Identify critical control points (CCPs), (3) Establish critical limits for each CCP, (4) Establish monitoring procedures, (5) Establish corrective actions when monitoring shows deviation, (6) Establish verification procedures, (7) Establish record-keeping and documentation. FSMA 2011 shifted US food safety from reactive (response) to preventive (proactive controls); seven rules include Preventive Controls for Human Food, Produce Safety, FSVP (foreign supplier verification), and Sanitary Transportation.

4HPAI H5N1 2024 US dairy cattle outbreak — first detection March 2024 in Texas dairy cattle (H5N1 clade 2.3.4.4b); unusual host (bovine), mammary tropism with high viral titers in milk (pasteurization inactivates virus), cattle-to-cattle and cattle-to-poultry spillback, sporadic human cases (mild conjunctivitis) in dairy workers. USDA/FDA/CDC coordinated One Health response — surveillance of bulk tank milk, interstate movement testing, farmworker PPE, seroepidemiology. High-yield for 2026 exam.

5Epi curve interpretation: POINT SOURCE (single sharp peak approximating log-normal, all cases within one incubation period — e.g., contaminated potluck), CONTINUOUS COMMON SOURCE (plateau, cases over multiple incubation periods — e.g., ongoing water contamination), PROPAGATED (multiple peaks ~1 incubation period apart, person-to-person or vector-borne). Bradford Hill criteria: strength, consistency, specificity, temporality (required), biological gradient, plausibility, coherence, experiment, analogy.
