1.) The clinical description aims more at the signs and
symptoms. Epidemiologic description focuses more on social and physical
environments, economic factors or individual factors such as gender and age.
These two descriptions are similar because they both deal with clues. These two
descriptions gather signs and symptoms in different approaches.
2.) A. This represented a movement away from super natural
explanation of disease causation to a rational account of the origin of human
B. Since John Snows natural experiment, William Farr
promoted innovative use of vital statistics.
C. Natural experiments would give knowledge to people on
ways to stop a disease such as John Snows natural experiment story.
D. This made it possible to classify a disease by specific
casual organism and group together diseases.
3.) A. Determinants- Factors or events that is capable of
bringing about a change in health. Ex: Biologic agents, Chemical agents, less
specific factors like stress, drinking and others.
B. Distribution- Frequency of disease occurrence may vary
from one population group to another. EX: Coronary heart disease occurrence
differs between Hispanics and non- Hispanics.
C. Morbidity and
Mortality- Morbidity is illness and Mortality is death.
4.) A. Epidemic is an outbreak of a disease that seems to be
spreading faster than usual.
B. In 1976, the first documentation of Ebola was recorded
then recently appeared again and was considered epidemic.
C. Pneumonia and Influenza
5.) Natural experiment refers to “naturally occurring
circumstances in which subsets of the population have different levels of
exposure to a supposed casual factor in a situation resembling an actual
experiment where human subjects would be randomly allocated to groups. Changes
in legislation to limit smoking in public places or to increase the speed limit
on highways would be considered natural experiments because they both rely on
what causes accidents have occurred or are occurring because of the stats of a
certain place. For example, if the speed limit sign near a school is 50mph and
kids are constantly afraid to cross the street and there are rosaries in that
area often then maybe to an extent the speed limit should be much slower around
schools from the statistics you have recorded.
