What does Epidemiology study? - (answer) Person, place, & time
How does Epidemiology differ from studying medicine? - (answer) Medicine targets individuals while
Epidemiology targets populations
Fixed (Static) Population - (answer) membership permanent; population defined by life event (i.e.,
9/11)
Dynamic (Open) Population - (answer) membership transitory, people can come & go (i.e., UK
students)
John Snow - (answer) "Father of Epidemiology" - identified how Cholera was transmitted before we
knew what the actual bacteria was
Hippocrates of Kos - (answer) "Father of Medicine" - dismissed supernatural, superstitious, and
religious causes of disease, invented the words "epidemic" and "endemic"
Girolamo Fracastoro - (answer) beginning of germ theory / proposed 3 modes of disease transmission
(direct, through air, & contact with fomites)
John Graunt - (answer) produced first life table giving probabilities of survival to each age / admitted to
Royal Society on its merits

Epidemiologic Triad - (answer) Agent, Host, & Environment
Direct Transmission - (answer) occurs when there is physical contact between an infected person and a
susceptible person
Indirect Transmission - (answer) occurs when there is no direct human-to-human contact.
Continuing Common Source - (answer) epi curve that occurs when persons are exposed to the same
source but exposure is prolonged over a period of days, weeks, or longer. Curve rises gradually and might
plateau.
Point Source - (answer) epi curve that occurs when persons are exposed to the same source over a
brief time, such as through a single meal or at an event. The number of cases rises rapidly to a peak and
falls gradually
Propagated Source - (answer) epi curve that occurs when there is no common source because the
outbreak spreads from person-to-person. The graph will assume the classic epi curve shape of
progressively taller peaks, each being one incubation period apart.
Attack Rate - (answer) the proportion of an at-risk population that contracts the disease during a
specified time interval.
Attack Rate Ratio - (answer) compares the two proportions of people at risk (calculated by dividing one
quantity by the other)
Epidemic - (answer) a widespread occurrence of an infectious disease in a community at a particular
time.
Endemic - (answer) (of a disease) regularly occurring within an area or community.
