HOSA EPIDEMIOLOGY PRACTICE TEST
ACTUAL EXAM PAPER 2026 QUESTIONS
WITH ANSWERS GRADED A+
⩥ Analytical Epidemiology. Answer: aims to research and study risk and
protector factors of diseases.
⩥ Pandemic. Answer: An epidemic occurring worldwide, or over a very
wide area, crossing international boundaries, and usually affecting a
large number of people.
Ex.. 1918 influenza (Spanish flu)
⩥ Distribution. Answer: The occurrence of diseases and other health
outcomes varies in populations, with some subgroups of the populations
more frequently affected than others.
⩥ Epidemic. Answer: sudden increase in occurrence of disease in a
population
usually within a specific geographic region or population
⩥ Exposures. Answer: Related to determinants,which pertain either to
contact with a disease-causing factor or to the amount of the factor that
impinges upon a group or individuals.
,⩥ Determinants. Answer: determinants Any factor that brings about
change in a health condition or other defined characteristic.
⩥ Morbidity. Answer: illness due to a specific disease or health
condition
⩥ Mortality. Answer: Death, usually on a large scale
⩥ Quanification. Answer: Refers to counting the cases of illness or other
health outcomes. Denotes the use of statistics to describe the occurrence
of health outcomes and measure their association with exposures
⩥ Hippocrates. Answer: departed from superstitious reasons for disease
outbreaks Wrote On Airs, Waters, and Places in 400 BC
Suggested disease might be associated with environmental factors
⩥ John Snow. Answer: (1813-1858)An English anesthesiologist who
innovated several of the key epidemiologic methods that remain valid
and in use today
Believed that cholera was transmitted by contaminated water and was
able to demonstrate this association.
⩥ Paracelsus. Answer: (1493-1541) was one of the founders of the field
of toxicology.
,The dose-response relationship
The notion of target organ specificity of chemicals
⩥ John Graunt. Answer: is considered by many historians to have
founded the science of demography, the statistical study of human
populations. He analyzed the vital statistics of the citizens of London
and wrote a book regarding those figures that greatly influenced the
demographers of his day.
⩥ Ramazzini. Answer: (1633-1714) is regarded as the founder of the
field of occupational medicine.
He authored De Morbis Artificum Diatriba (Diseases of Workers),
published in 1700.
⩥ Edward Jenner. Answer: (1749-1823) developed a method for
smallpox vaccination in 1796.
⩥ William Farr. Answer: (1807-1883)Appointed "Compiler of
Abstracts" in England, 1839
Developed a more sophisticated system for codifying medical conditions
Examined possible linkage between mortality rates and population
density (defined as number of persons per square mile)
⩥ Robert Koch. Answer: (1843-1910), a German physician
, Published Die Aetiologie der Tuberkulose in 1882
Koch's postulates demonstrated the association between a
microorganism and a disease.
⩥ Alexander Flemming. Answer: (1881-1955) discovered the anti-
microbial properties of the mold Penicillium notatum in 1928.
Antibiotic became available toward the end of World War II
⩥ carrier. Answer: individual - potential source of infection for others
can be infected or transferring from infected person to another
⩥ etiologic agent. Answer: etiologic agent pathogen responsible for
diseas
⩥ reservoir. Answer: primary habitat which the agent is normally found
and from which infection may result
⩥ vector. Answer: living transmitters of pathogen
⩥ vehicle. Answer: non-living transmitters
