primary
secondary
Tertiary

11. Primary prevention
Prevention is better than cure
Action is taken prior to the onset of disease, which removes the
possibility that disease will ever occur
Intervention is in the pre pathogenensis phase
Primary prevention is far more than preventing the occurrence of disease
and prolonging the life

12. Primary prevention is holistic approach designed to promote
health or to protect against specific disease(agents) and hazards in
environment
 Low cost
 Safe
 The individual is not yet exposed to
pain and swelling

13. The approaches for primary prevention
recommended by WHO
Primordial prevention
It is the prevention of the emergence
or development of risk factors in
countries or popultion groups in
which they have not yet appeared.
The main intervention individual or
mass education

14. Population (mass strategy)
It is directed at the whole population irrespective of individual risk level so as
to bring about behavioral and life changes

15. High risk strategy
It aims to bring preventive care to individual at special risk
These three approaches are complimentary and should be implemented
together to have an impact on the population
THE MODE OF INTERVENTION IN PRIMARY PREVENTION ARE-
Health promotion
specific protection

16. Health promotion

of the human being individually and in the group.
 It includes the promotion of health, the prevention of sickness and curative
and restorative medicine in all its aspects

18. SECONDARY PREVENTION
Action which halts the progress of disease at its incipient stage and
prevents complication
Specific interventions
Early diagnosis
Adequate treatment

19. • The earlier disease is diagnosed and treated the better it is from the point of
view of prognosis and preventing further complications or long term
disability
• Strictly speaking early diagnosis and treatment cannot be considered
prevention since the disease process is already started.
• However it has been included under prevention because this mode of
intervention will intercept the disease and prevent further complication.

20. Reducing the high mortality and morbidity
of certain disease like hypertension
Reducing the mortality and
morbidity of certain disease
