Biblical Principals
Pikuah nefesh - sanctity of human life
Tikun olam – Biblical - repair the world
Ancient India and China - sanitation
Ancient Greece
Hippocratic oath - do no harm
Healthy body-healthy mind
City states
Religion – Charity, after-life

Medieval
The Church - Religious institutions, relieve
suffering, care of the poor
Aristocracy – noblesse oblige
Universities – royal charters
Cities – royal charters, municipal government
sanitation, hospitals
Guilds – mutual benefit “friendly” societies

Miasma and germ theories
Social hygiene
Scientific and PH advances during 19th-20th centuries
Government responsibility –local, state and national
Collective bargaining for health benefits
Tragic distortions of social hygiene – eugenics, genocide
Human rights – Nuremberg, Tuskegee, Helsinki
Universal right to health care (Health for All)
Self responsibility (lifestyle) in health
Advancing technology and rising costs
Public awareness and expectations
Pragmatism and science

Ethics in Epidemiology
Ethics is a branch of philosophy that deals with
distinctions between right and wrong – with the
moral consequences of human actions.
The ethical principles that arise in epidemiologic
practice and research include:
Informed consent
Confidentiality
Respect for human rights
Scientific integrity

Ethics, Values, and Mission Statements in
Epidemiology
• Core values - fundamental ethical and basic scientific values
support mission and purpose of the profession
• Epidemiologic mission is to acquire new scientific
information needed to maintain, enhance, and promote the
public's health
• Different opinions about core values
• Values in the profession may gradually evolve over time e.g.
euthanasia
• Core values in epidemiology are closely related to core
values in the broader field of public health.
• "Values define us as a group of public health professionals;
values drew many of us into public health”.
Coughlin SS. Epidemiologic Review. 2000;22:169-175

Moral Reasoning as Guide for Action
•

•
•
•
•
•

•
Mandatory and voluntary
Benefits – for society and individuals
Do no harm - balance potential good and harm
Action vs. non action
Autonomy - right of self determination
Justice and equity
Case based approach
Design and conduct of research
Application of knowledge
Conflict of interests – disclosure
Autonomy - informed consent, confidentiality

Coughlin S. Emerging Themes in Epidemiology, 2006
Ethical Issues in PH
Routinely in public health, scientific considerations blend
with political and ethical conflicts, and questions of
autonomy, individual rights, coercion, justice,
community, the common good, the norms of research,
and multi-cultural values are central.
In public health today several different types of political
and moral theory overlap, converge, and contend with
one another, including libertarian liberalism, egalitarian
liberalism, utilitarianism, human rights frameworks,
and communitarianism.

New Public Health:
Individual and Population Health
Individual Health
Population Health
Bioethics = human rights,
civil liberties and
individual autonomy
approach, medicalized
system, confidentiality,
privacy,
personalized
Public health = utilitarian,
paternalistic, social and legal
responsibility to protect the
public health, community
orientation, accountability,
universal, governmental
responsibility
10
Ethics in PH
• Moral imperative of PH to ensure and protect the
health of the population and the individual
• Ethical foundations traditionally implicit in PH
• The right to health
• Responsibility fro population health
• Renewed awareness of and accountability
• Conflict between individual and community rights
• Effects of doing or not doing public health
interventions or “best practices”
• New issues all the time – diasters, genocide
11
When and When Not to Act
• Public (community) right to protection and best
available standards
• Dangers/costs of not acting exceed those of acting
• Judgment, experience, evidence, ethics
• Experience of Good Public Health Practice (GPHP)
• Threats of preventable mortality or risk factors
• Public right to know
• Individual rights
• Balance of contradictions
• Accountability, transparency
12
Why Study Ethics in PH
• Many issues of conflict between good of the
individual and good of society
• Immunization, chlorination, fluoridation
• Food fortification
• HIV/AIDs, MDRTB, DOTs vs. DOTS Plus
• Aging and chronic diseases
• Genetically modified foods
• Technology and resource allocation
• Stem cell research
• The Case-for-Action
13
Basic Questions
• Does society’s responsibilities = paternalism?
• Does freedom of individual = rejection of
responsibility of the state in health?
• Do we need informed consent for all PH
interventions?
• Do individual rights over-ride social responsibility?
E.g. AIDS contact tracing
• “Precautionary Principle” = must prove zero risk of
an new medication or PH intervention?
• Equity in health?
• Adequacy of funding and its allocation?
14
Old-New Battles
• UK Variolists oppose vaccination vs. smallpox C19th
• US Opposition to public health departments in 1920s
• UK GPs oppose immunization with pertussis (1980s)
and MMR (2002+)
• AMA opposes to national health insurance 1920s +
• Civil rights vs. HIV control, 1980s US
• Anti-fluoridation 1950s to present
• Resistance to innovations e.g. MMR, Hib, Pap smear
• Anti-food fortification in Europe
• Anti-genetic engineering of food in Europe

PH Law and Ethics
• Gov’t obligation to protect health of the population
• Power of government to legislate, tax, spend,
regulate, punish
• Restriction of personal and business liberties e.g.
seat belt laws; smoking restrictions vs. human rights
• Economic, social impact of intervention vs. nonintervention e.g. inequities of the poor and rural
• Laws enacted by legislative bodies
• Court decisions
• Public scrutiny
• Accountability

Public Health: “the Slippery Slope”
• 1920’s-1930’s: Eugenics movement
• 1930’s-1940’s: Mass sterilization of "defectives" in
United States and Sweden.
• 1930-1940’s: Mass murder of “defectives” in
Germany (750,000)
• 1940’s: Quarantining as pretext for ghettos by Nazis
• 1940s: Concentration camps, human experimentation
• 1940s: The Holocaust (6 million Jews and others)
• 1946 – Nuremberg Trials

Changing Concepts of Disease
• 1960s – Ivan Illitch and McKeowan – medical care of
little value; health gains result of sanitary and
nutritional adavances
• 1970s – Marc Lalonde Health Field Concept: genetic,
environment (physical and social), lifestyle and
medical factors in health
• Evidence of risk factors for disease e.g. smoking, diet
exercise e.g. smoking and Framingham studies
• Blaming the victim vs. self responsibility?
• Health targets US Surgeon General and WHO
