Review 2026/2027
Introduction to Epidemiology - Correct answer✅✅
The study of the distribution and determinants of health-related states or events in specified
populations and the application of this information to control health problems: - Correct answer✅✅
Epidemiology
Why are the reasons we study epidemiology? - Correct answer✅✅ Monitor the health of populations
Identify the determinants of health and disease in communities
Prevent and halt the spread of disease
Evaluate interventions that prevent disease and maintain health
Guide public policy
What are the three factors of the epidemiologic triangle? - Correct answer✅✅ Agent (cause of
infection, i.e. bacteria, fungi, parasites, viruses)
Host (harborer of infection, i.e. person)
Environment (everything that is external to the host including physical, biological, social and cultural
factors)
What are the three 'Host Factors'? - Correct answer✅✅ 1. Resistance
2. Active Immunization
3. Passive immunization
What is the difference between active and passive immunization? - Correct answer✅✅ Active:
immunity resulting from contact with disease causing agents
Passive: immunity transferred from an immunized person to non-immunized person (i.e. breast milk
from mom to baby)
, What is the difference between vertical and horizontal modes of transmission? - Correct answer✅✅
Vertical: infection passes from parent to child
Horizontal: person to person spread of infection thorough one of four routes of transmission
What are the 4 routes of transmission? - Correct answer✅✅ 1. Direct/indirect
2. Airborne
3. Common vehicle (infectious agent transported through a medium such as saliva, blood, food, and
water)
4. Vector borne: carrier of infectious agent (ticks, mosquitos)
What is the difference between incubation period and communicable period? - Correct answer✅✅
Incubation: the interval between invasion and when signs appear
Communicable: the interval during which infectious agents transferred from one person to another
The number of people who died within a population; a measure of death (usually expressed as the
number of deaths per 1000 individuals per year) - Correct answer✅✅ Mortality
The state of being diseased or unhealthy within a population; a measure of disease - Correct
answer✅✅ Morbidity
What is the definition of prevalence? - Correct answer✅✅ the health outcome that is measured in a
particular population at a SINGLE POINT IN TIME
ex. in 2011 there were 2 million women living with breast cancer in the US
