and promoting health, through the organized efforts of
society…” (Acheson, 1988).

PHCIH_BPH_3rd Semester 4
5. Public Health
• “Public health is the science and art of preventing disease,
prolonging life and promoting physical health and efficacy
through organized community efforts for the sanitation of
the environment, the control of communicable infections,
the education of the individual in personal hygiene, the
organization of medical and nursing services for the early
diagnosis and preventive treatment of disease, and the
development of social machinery which will ensure every
individual in the community a standard of living adequate
for the maintenance of health; so organizing these benefits
in such a fashion as to enable every citizen to realize his
birthright and longevity.”(Winslow,1920)
PHCIH_BPH_3rd Semester 5
6. Public Health
•Last defined public health as “one of the efforts to
protect, promote and restore the people’s health. It is
the combination of sciences, skills and beliefs that is
directed to the maintenance and improvement of the
health of all the people through collective or social
actions”.(Last, 2001)
PHCIH_BPH_3rd Semester 6
7. Elements embedded in definitions
•Decision Making based on data and evidence (Vital
Data, Surveillance, outbreak investigation,)
•A focus on population rather than individuals
•A goal of social justice and equity
•An emphasis on prevention rather than curative care
PHCIH_BPH_3rd Semester 7
8. International Health
• It was the term used for health work abroad
•geographic focus on developing countries and often
with a content of infectious and tropical diseases,
water and sanitation, malnutrition, and maternal and
child health( Brown,2006)
PHCIH_BPH_3rd Semester 8
9. International Health
•International health is defined by Merson, Black, and
Mills as “the application of the principles of public
health to problems and challenges that affect low and
middle-income countries and to the complex array of
global and local forces that influence them”(Mearson
et.al,2006)
(international health is also used as a synonym for
global health)
PHCIH_BPH_3rd Semester 9
10. •International health, focuses on the health issues,
especially infectious diseases, and maternal and child
health in low-income countries. (Global Health
Action,2010)
PHCIH_BPH_3rd Semester 10
11. International Health
•The term ‘international health’ has also been used to
refer to ‘the involvement of countries in the work of
international organizations such as WHO, usually
through small departments of international health in
the Ministries of Health and as development aid and
humanitarian assistance
PHCIH_BPH_3rd Semester 11
13. •Collaborative (or collective) emphasises the critical
importance of collaboration in addressing all health
issues and especially global issues which have a
multiplicity of determinants and a complex array of
institutions involved in finding solutions.
PHCIH_BPH_3rd Semester 13
14. •Trans-national (or cross-national) refers to the
concern of global health with issues that transcend
national boundaries even though the effects of global
health issues are experienced within countries. Trans-
national action requires the involvement of more than
two countries, with at least one outside the traditional
regional groupings, without which it would be
considered a localised or regional issue.
• At the same time, trans-national work is usually
based on strong national public health institutions.
PHCIH_BPH_3rd Semester 14
15. •Research implies the importance of developing the
evidence-base for policy based on a full range of
disciplines and especially research which highlights the
effects of trans-national determinants of health.
•Action emphasizes the importance of using this
evidence-based information constructively in all
countries to improve health and health equity.
PHCIH_BPH_3rd Semester 15
16. •Promoting (or improving) implies the importance of
using a full range of public health and health promotion
strategies to improve health, including those directed
at the underlying social, economic, environmental and
political determinants of health.
PHCIH_BPH_3rd Semester 16
17. •Health for all refers back to the Alma Ata Declaration
and positions global health at the forefront of the
resurgence of interest in multi-sectoral approaches to
health improvement and the need to strengthen
primary health care as the basis of all health systems
PHCIH_BPH_3rd Semester 17
18. Global Health
•Global health is focused on people across the whole
planet rather than the concerns of particular nations.
•Global health recognizes that health is determined by
problems, issues and concerns that transcend national
boundaries
•‘worldwide improvement of health, reduction of
disparities, and protection against global threats that
disregard national borders’(Macfarlane et al,2008)

22. Evolution of International Health
•Paul Russel said "Nothing in this earth is more
international than disease"
•It is obvious that health and disease of people in one
country are related to health and disease in other
countries
•This necessitates the need for international
cooperation in the area of health
PHCIH_BPH_3rd Semester 22
23. Cont..
•Health and disease have no political or geographical
boundaries
•Disease in any part of the world is constant threat to
other parts
•In order to protect from the spread of disease from
one country to another many attempts were made in
the past by individual ruler and states to place barriers
against infection by detection and isolation of
incoming travelers
PHCIH_BPH_3rd Semester 23
24. • Diseases spread from one country to another. Examples are
syphilis, plague, cholera, influenza and AIDS.
• In Indian context Syphilis was earlier known as ‘Firangi
Rog’ because it was believed to have been brought to India
by the Europeans.
• Research, knowledge and developments in the field of
health should not be confined to any one country but
should, rather, be freely available to the whole mankind.
PHCIH_BPH_3rd Semester 24
25. •Poor health conditions in a country are associated
with and lead to poor development.
•The marked disparity between the developed and
underdeveloped countries is a danger for world
peace.
PHCIH_BPH_3rd Semester 25
26. •Population explosion in the world has to be contained
if the human race has to survive.
•There are countries in the world with near zero
population growth, while there are many countries
with very high rates.
• The former cannot remain silent spectators to the
high birth rates in many parts of the world when the
survival of mankind itself is at stake.
PHCIH_BPH_3rd Semester 26
27. Cont..
•In the 14th century a procedure known as
"Quarantine" was introduced in Europe to protect
against importation of plague
•After that Quarantine become an established practice
in many countries
•Different countries adopted different quarantine
procedures
•This was the origin of International health work
PHCIH_BPH_3rd Semester 27
28. Cont...
•Due to lack of scientific knowledge regarding the
causation and mode of spread of diseases quarantine
failed in its objective
•As 40 day detention obstructed and caused serious
inconvenience to international trade and travel
•It becomes necessary for international agreement and
cooperation on quarantine matters to control
communicable disease
