Middle Kingdom Egypt (2700-2000 B.C.) showed the presence of drainage systems

Code of Hammurabi (earliest written record concerning public health), King of Babylon in 1900 B.C. included laws pertaining to physicians and public health practices

1500 B.C. first written hygienic code

• keep a clean body

• protect against contagious diseases

Public Health in Classical Cultures (500 B.C. to 500 A.D.)

Greeks began to travel to EgyptGreeks took information from the Babylonians,

Egyptians, Hebrews and other people of the Eastern Mediterranean

Included these in the Greek philosophy of health and medicine

Active in the practice of community sanitationSupplemented water from city wells by water

from the mountains if necessary

Page 7: Public Health Historical Perspective Dr. Anjum Odhwani MD, MPH

Had extensive systems for public and private hygiene

Brought clean water into their cities using aqueducts

Had extensive bath and wash houses Had system for getting rid of garbage and other

wastes. Built the first hospital

Page 8: Public Health Historical Perspective Dr. Anjum Odhwani MD, MPH

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

Page 9: Public Health Historical Perspective Dr. Anjum Odhwani MD, MPH

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”

Page 10: Public Health Historical Perspective Dr. Anjum Odhwani MD, MPH

Public Health of the Middle Ages(500-1500 A.D.)

During the 7th century Islam appeared religion stressed cleanliness one problem---each Hajj (pilgrimage to

Mecca) was followed by a cholera pandemic

crusades brought cholera back to urbanizing Europe

Page 11: Public Health Historical Perspective Dr. Anjum Odhwani MD, MPH

Public Health of the Middle Ages(500-1500 A.D.)

Leprosy spread from Egypt to Asia Minor to Europe lepers were banished lepers succumbed quickly to starvation and

elements inhumane measures ended leprosy in Europe

• One of the earliest recorded epidemic disease was Leprosy

Page 12: Public Health Historical Perspective Dr. Anjum Odhwani MD, MPH

Public Health of the Middle

Ages (500-1500 A.D.)

Ghengis Khan brought plague west in 1219Millions died in the known world

In some parts of France only 1in 10 survived

Known as the Black DeathEpidemics in Europe occurred periodically

1603, 1625, 1665, 1743, 1759, 1790

Control measures quarantine of sailors at ports for 2 months

Page 13: Public Health Historical Perspective Dr. Anjum Odhwani MD, MPH

Public Health in the Renaissance Period (1500-1700 A.D.)

Time of great trade experience of the Dark Ages was not forgotten

People now asked how diseases arose began to think that disease was not a punishment

from GodCareful record keeping showed that infections killed

the godly and the godless alikeGrowing belief that it was environmental factors that

caused disease e.g. malaria= bad air

Page 14: Public Health Historical Perspective Dr. Anjum Odhwani MD, MPH

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

Page 15: Public Health Historical Perspective Dr. Anjum Odhwani MD, MPH

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

Page 16: Public Health Historical Perspective Dr. Anjum Odhwani MD, MPH

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)

Page 17: Public Health Historical Perspective Dr. Anjum Odhwani MD, MPH

Public Health in the Eighteenth Century

The first US census was taken in 1790Average age at death in the US was 29 In 1798 Marine Hospital Service was

formed to deal with diseases on vessels

Page 18: Public Health Historical Perspective Dr. Anjum Odhwani MD, MPH

Public Health in the Nineteenth Century

It was realized that social and sanitary conditions impacted the economy

Industrialization led to the concentration of populations in cities

Better agricultural methods produced better nutrition

First sanitation legislation in England 1837 National Vaccination Board

Page 19: Public Health Historical Perspective Dr. Anjum Odhwani MD, MPH

Public Health in the Nineteenth Century

Edwin Chadwick 1842 Report on an Inquiry into the Sanitary

Conditions of the Laboring Population of Great Britain

General Board of Health for England 1848John Simon - 1848

first medical officer of London

Page 20: Public Health Historical Perspective Dr. Anjum Odhwani MD, MPH

Public Health in the Nineteenth Century

John Snow - 1850 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 )

Page 21: Public Health Historical Perspective Dr. Anjum Odhwani MD, MPH

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

Page 22: Public Health Historical Perspective Dr. Anjum Odhwani MD, MPH

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

Page 23: Public Health Historical Perspective Dr. Anjum Odhwani MD, MPH

Public Health in the Nineteenth Century

Between 1877 and the end of the century many bacteria that caused particular infectious diseases were identified

Page 24: Public Health Historical Perspective Dr. Anjum Odhwani MD, MPH

Public Health in the Colonies

Massachusetts first to record births and deaths - 1639 law against pollution of Boston Harbor - 1647 Isolation of smallpox patients and ships - 1701 hard to enforce no agency to do it

Even the Federation of Colonies had little luck really dealing with public health issues

Page 25: Public Health Historical Perspective Dr. Anjum Odhwani MD, MPH

Eighteenth century America

1790 George Washington ordered the first census of the population to be made

1798 the Marine Hospital Service formed to deal with diseases brought in by ships

1799 some cities (Boston, Philadelphia, New York and Baltimore) formed Municipal Boards of Health

Page 26: Public Health Historical Perspective Dr. Anjum Odhwani MD, MPH

19th Century America

Population increasesCountry increases in sizePublic health measures stationaryEpidemics common for

smallpox, yellow fever, cholera, typhoid, typhus

Endemic diseases tuberculosis, malaria

Page 27: Public Health Historical Perspective Dr. Anjum Odhwani MD, MPH

Shattuck Report - 1850

Lemuel Shattuck - legislator - MA interested in public health appointed to study sanitary problems in MA document he wrote was ahead of its time no national or state PH programs at the time

Page 28: Public Health Historical Perspective Dr. Anjum Odhwani MD, MPH

Shattuck's Recommendations

Establish state and local boards of healthHire sanitary police or inspectorsCollect and analyze vital statisticsExchange data and informationSanitation programs for towns and

buildingsStudy health of school children

Page 29: Public Health Historical Perspective Dr. Anjum Odhwani MD, MPH

Recommendations continued

Study, supervise and/or control TB, alcoholism, mental disease

Supervise and study immigrantsErect model tenements, bath/wash housesControl smokeControl food adulteration

Page 30: Public Health Historical Perspective Dr. Anjum Odhwani MD, MPH

Recommendations continued

Establish nursing schoolsTeach sanitary science in medical schoolInclude prevention in clinical practiceGet routine physical examsKeep records of family illnessesPreach health from the pulpit

Page 31: Public Health Historical Perspective Dr. Anjum Odhwani MD, MPH

Shattuck Report - 1850

Impact of this report was to start the Modern Era of Public Health in America

Proposals took some time to implement Massachusetts's State Board of Health was

founded in 1869 and by 1900 only 38 states had state health departments

There were few county health departments

Page 32: Public Health Historical Perspective Dr. Anjum Odhwani MD, MPH

Public Health in the Twentieth Century

At the beginning of the century Life expectancy was less than 50 years Leading causes of death were communicable

diseases (influenza, pneumonia, tuberculosis and GI infections)

Vitamin deficiency diseases were common including rickets, pellagra and scurvy

Deaths associated with pregnancy and childbirth were also high

Page 33: Public Health Historical Perspective Dr. Anjum Odhwani MD, MPH

Public Health in the Twentieth Century

Health resources development period (1900-1960) is further divided into The reform phase (1900-1920) The 1920s The great depression and World War II The post war years

Page 34: Public Health Historical Perspective Dr. Anjum Odhwani MD, MPH

Page 39: Public Health Historical Perspective Dr. Anjum Odhwani MD, MPH

Public Health in the Twentieth Century

The Great Depression and World War II 1935 The Social Security Act marked the

beginning of the involvement of the government in social issues including health

Public Health in the Twentieth Century

In 1970s, CDC conducted a study that examined premature death

Study revealed that approx 48% of all premature deaths were because of lifestyle or health behavior-choices people make

This led the way for U.S. government’s publication Healthy People: The surgeon General’s Report on Health Promotion and Disease Prevention
