2026 BIOD 102 Module 6 Exam Portage Learning Questions and
Answers 2026
Epidemiology & Public Health
1. Which term describes the study of how disease is distributed within a population
and the factors that determine that distribution?
• A) Etiology
• B) Epidemiology
• C) Morbidity
• D) Pathology
• Rationale: Epidemiology is the core science of public health, focusing on the
patterns and determinants of health-related states in specific populations.
2. When defining a "population" in an epidemiological context, which three metrics
must be addressed?
• A) Age, Gender, Ethnicity
• B) Person, Place, Time
• C) Species, Habitat, Era
• D) Health, Wealth, Education
• Rationale: These three metrics are the fundamental pillars used to categorize
and analyze a specific aggregate of people for research.
3. Which term refers specifically to the death of a person?
• A) Morbidity
• B) Mortality
• C) Etiology
• D) Pathogenesis
, • Rationale: Mortality describes the outcome of death, while morbidity refers to the
symptoms, disabilities, or general suffering caused by a disease.
4. A scientist is studying the "Etiology" of a new respiratory virus. This means they
are investigating:
• A) The number of people who died from it
• B) The mechanism or cause of the disease
• C) The geographical spread of the virus
• D) The best treatment for infected patients
• Rationale: Etiology is the study of causation; understanding it allows public health
officials to develop effective prevention programs.
5. Which of the following is an example of Indirect Transmission of a disease?
• A) A fecal-to-oral transmission from poor hand hygiene
• B) A mosquito carrying malaria to a human host
• C) Blood-to-blood contact during a medical procedure
• D) Skin-to-skin contact during a physical exam
• Rationale: Indirect transmission involves an intermediate, such as a "vector" (the
mosquito) or a "vehicle" (a contaminated doorknob).
6. What is the primary difference between Public Health and Clinical Practice?
• A) Public health uses medicine; clinical practice does not.
• B) Public health focuses on the population; clinical practice focuses on the
individual.
• C) Public health is only for infectious diseases; clinical practice is for chronic
ones.
• D) There is no difference; they are the same field.
• Rationale: Clinical practice treats the patient sitting in the office, whereas public
health develops policies to protect the entire community.
, 7. If a health department executes procedures to gather pertinent health data
directly from hospitals, it is conducting:
• A) Passive surveillance
• B) Active surveillance
• C) Clinical trials
• D) Morbidity reporting
• Rationale: Active surveillance involves officials actively seeking out data,
whereas passive surveillance relies on providers to report data voluntarily.
8. Which of the following is considered a Social Determinant of Health (SDOH)?
• A) Genetic susceptibility
• B) Neighborhood and physical environment
• C) Viral mutation rate
• D) Blood type
• Rationale: SDOH are situational factors (like housing, education, and social
context) that impact health outcomes.
9. Smallpox was successfully eradicated globally in 1980 primarily through:
• A) Improved antibiotic use
• B) Global vaccination efforts
• C) Natural immunity
• D) Water filtration systems
• Rationale: The variola virus was eliminated as a human threat through a
massive, coordinated worldwide vaccine campaign.
10. In a case-control study, the most appropriate measure of association to use is
the:
• A) Relative Risk
• B) Odds Ratio
