3. Health:
Health is a state of complete physical,
mental and social wellbeing and
not merely an absence of disease
or infirmity

4. • The International Classification
of Diseases (ICD) is the
standard diagnostic tool for
epidemiology, health
management and clinical
purposes.

5. • This includes the analysis of the
general health situation of
population groups. It is used to
monitor the incidence and
prevalence of diseases and
other health problems.

6. • It is used to classify diseases
and other health problems
recorded on many types of
health and vital records
including death certificates and
health records.

7. • In addition to enabling the
storage and retrieval of
diagnostic information for
clinical, epidemiological and
quality purposes,
• these records also provide the
basis for the compilation of
national mortality and morbidity
statistics by WHO Member
States.

8. • It is used for reimbursement
and resource allocation
decision-making by countries.

9. :Disease
The state of un-wellbeing

10. A system for classification of
diseases is needed whereby
diseases could be grouped
according to certain
common characteristics,
that would facilitate the
statistical study of disease
phenomena.

11.  Many approaches were tried to
classify diseases.
 Jhon Graunt in 17th century in his
study of Bills of Mortality,
arranged diseases in an
alphabetical order.

12.  More scientific approach
was adopted in classifying
disease according to certain
characteristics.

13.  Classification was as follow:
 a-the part of the body affected
 b-the etiologic agent
 c-the kind of morbid change
produced by the disease
 The kind of disturbance of
function produced by the
disease or injury.
