Public Health
Historical PerspectiveDr. Anjum Odhwani MD, MPH
Public Health in Primitive Societies
Have a sense of community hygiene bury excreta burial of the dead tribal rituals for the diseased temporary isolation for the sick smoke for fumigation
Public Health in Ancient Societies (Before 500 B.C.)
Northern India - excavations dating from around 2000 B.C. have evidence of bathrooms, drains and sewers
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
Public Health in Ancient Societies (Before 500 B.C.)Sumerian clay tablet from 2100 B.C. contains
prescriptions for drugsMinoans lived on Crete (3000-1430 BC)
drainage systems, toilets, water flushing system
Myceneans 1430-1150 BC same as Minoans
Egyptians knew more than 700 drugs and were some of the healthiest of ancient civilizations.
Public Health in Ancient Societies (Before 500 B.C.)Hebrews wrote Book of Leviticus in about
1500 B.C. first written hygienic code
• keep a clean body
• protect against contagious diseases
• isolation for lepers
• disinfecting of home after an illness
• sanitation of campsites
• protect food and water
• hygiene of maternity
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
Public Health in Classical Cultures (500 B.C. to 500 A.D.)Romans
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
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 one problem---each Hajj (pilgrimage to
Mecca) was followed by a cholera pandemic
crusades brought cholera back to urbanizing Europe
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
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
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
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
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
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
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
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 )
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
Between 1877 and the end of the century many bacteria that caused particular infectious diseases were identified
1875 to 1900 The Bacteriological Period of Public Health
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
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
19th Century America
Population increasesCountry increases in sizePublic health measures stationaryEpidemics common for
smallpox, yellow fever, cholera, typhoid, typhus
Endemic diseases tuberculosis, malaria
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
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
Recommendations continued
Study, supervise and/or control TB, alcoholism, mental disease
Supervise and study immigrantsErect model tenements, bath/wash housesControl smokeControl food adulteration
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
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
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
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
Public Health in the Twentieth Century
Period of social engineering (1960-1973)Period of health promotion (1973 to
present)
Public Health in the Twentieth Century
The Reform Phase of Public Health Involved both social and moral as well as health
issues Public health nursing started with a school
nursing program in New York in 1902 In 1906 the passage of the Pure Foods and Drugs
Act In 1910 New York passed Worker’s
Compensation Act
Public Health in the Twentieth Century
First School of Public Health was established in 1918 at Johns Hopkins University
1918 was the birth of school health educationBirth of first national level volunteer health
agencies American Cancer Society 1913 Rockefeller Foundation established 1913
Public Health in the Twentieth Century
The 1920s Period of slow development in Public Health Prohibition produced decline in alcoholics and
alcohol related deaths Number of county health departments rose to
467 Life expectancy in 1930 risen to 59.7 years
Public Health in the Twentieth Century
The Great Depression and World War II by 1933 private resources could no longer meet
the needs of the people who needed assistance Beginning in 1933, President Roosevelt’s New
Deal created agencies and programs for public works
Building of hospitals and laboratories, control of malaria and the construction of municipal water and sewer systems
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
World War II decreased the availability of funds and resources for public health, but led to the development of many important medical discoveries that were made available once the war ended
Public Health in the Twentieth Century
The post war years Antibiotic penicillin was made available Insecticide DDT to kill insects that transmitted
communicable diseases was made available Communicable Disease Center was set up in
Atlanta during the war, now known as the Center for Disease Control and Prevention (CDC)
Public Health in the Twentieth Century
The post war years Two major events in the 1950s
• Development of a vaccine to prevent polio• President Eisenhower’s heart attack focused
attention on the nations number one killer, heart disease
Public Health in the Twentieth Century
Period of Social Engineering 1965 passage of the Medicare and Medicaid
bills• Medicare provides for health care to the elderly and
some disable people
• Medicaid provides health care for the poor
Period of Health Promotion (1974-present) Recognition that the greatest potential for
saving lives is by education and life-style changes by individuals
Public Health in the Twentieth Century
Situation by the end of the Twentieth Century Life expectancy increased by 30 years Major infectious diseases brought under control Infant and maternal mortality rates decreased
by 90 and 99% respectively Safer workplaces Safer and healthier foods
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
Major Eras in Public Health History in the United StatesPrior to 1850 Battling Epidemics1850–1949 Building State and Local
Infrastructure1950–1999 Filling Gaps in Medical Care
DeliveryAfter 1999 Preparing for and Responding to
Community Health Threats
Public Health in the Twenty First Century
Problems to be faced Health care delivery Environmental problems Lifestyle diseases Alcohol and other drug abuse New communicable diseases or old diseases
that have become resistant to drug therapy
