Public Health in Classical Cultures
(500 B.C. to 500 A.D.)
 Greeks began to travel to Egypt

Public Health of the Middle Ages
(500-1500 A.D.)
 Dark Ages in Western Europe (500-1000
A.D.)
• saw the fall of Rome due to evil behavior
• went to the opposite extreme
– immoral to view one’s own body
– seldom bathed
– filthy clothes; used perfume
– diets were poor; used spices
– sanitation ignored; waste in streets
• many pandemics
Public Health of the Middle Ages
(500-1500 A.D.)
 Both pagan rites and Christian beliefs
blamed disease on supernatural causes.
 Christians generally believed that disease
was a judgement from God for sin
 This led to a failure to prevent the spread of
communicable diseases
 This is often called “The spiritual era of
Public Health”
Public Health of the Middle Ages
(500-1500 A.D.)
 During the 7th century Islam appeared
 religion stressed cleanliness

Mecca) was followed by a cholera
pandemic


experience of the Dark Ages was not forgotten
 People now asked how diseases arose
began to think that disease was not a
punishment from God
 Careful record keeping showed that infections
killed the godly and the godless alike
 Growing belief that it was environmental factors
that caused disease e.g. malaria= bad air

Public Health in the Renaissance
Period (1500-1700 A.D.)
 In reality conditions did not change much in
the Renaissance period
 Careful observations led to the recognition
of separate diseases

cholera, typhoid, TB, smallpox, etc.
 Explorers, traders and colonists took
indigenous European diseases and spread
them to indigenous peoples in the New
World
Public Health in the Eighteenth
Century
 Although there had been a recognition of the
role of the environment as a cause of disease,
living conditions were not conducive to good
health
 This period had the beginnings of
industrialization and urbanization
 Living conditions were poor and overcrowded,
water supplies were contaminated and working
conditions were unsafe
Public Health in the Eighteenth
Century
 Significant milestone for both medicine and
Public Health occurred in 1796, when Dr.
Edward Jenner demonstrated the process of
vaccination as a protection against small
pox
 Before this there had been only variolation
(inoculation with small pox material)
Public Health in the Eighteenth
Century

formed to deal with diseases on vessels
Public Health in the Nineteenth
Century

conditions impacted the economy

deduced that cholera was caused by a small
entity in the water
used epidemiological data
Predated the discovery that micro-organisms
can cause disease
Predominant theory of contagious disease at the
time was the “miasma theory” (noxious
atmosphere or influence )
Public Health in the Nineteenth Century
 Ignaz Semmelweiss- 1850- decreased death-rate
of women from puerperal fever by introducing
hand washing
 Theory of spontaneous generation (living organisms
could arise from inorganic or nonliving matter)
 Pasteur in 1862 proposed the germ theory of
disease and later introduced pasteurization of
milk. Gave the death blow to the theory of
spontaneous generation.
 Joseph Lister - 1867 - antisepsis
Public Health in the Nineteenth Century
 Koch in 1876 demonstrated his postulates with
the anthrax bacillus
 He formulated 4 postulates contributing to germ
theory




The disease agent must be found in all cases of the
disease
The disease agent must be isolated in pure culture
Inoculation of this disease agent must produce the
same disease in healthy animals/people
The disease agent must be re-isolated from the
inoculated animal/person
Public Health in the Nineteenth Century
