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

• 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.

• 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.

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.
![Page 11: Classification of Diseases](https://reader035.fdocuments.in/reader035/viewer/2022062418/555cc47bd8b42a64718b52ed/html5/thumbnails/11.jpg)
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.
![Page 12: Classification of Diseases](https://reader035.fdocuments.in/reader035/viewer/2022062418/555cc47bd8b42a64718b52ed/html5/thumbnails/12.jpg)
More scientific approach was adopted in classifying disease according to certain characteristics.

Classification was as follow:
a-the part of the body affected b-the etiologic agent c-the kind of morbid change
