“Looking beyond mortality and disease - a common language to describe health”

As a new member of WHO Family of International Classification, ICF describes health and health-related domains as body functions and structures, activities and participation. The domains are classified from body, individual and societal perspectives. Since an individual’s functioning and disability occur in a context, ICF also includes a list of environmental factors.

ICF is useful to understand and measure health outcomes. It can be used in clinical settings, health services or surveys at the individual or population level. Thus ICF complements ICD-10, The International Statistical Classification of Diseases and Related Health Problems and therefore is looking beyond mortality and disease.


ICF and ICD-10

ICF and ICD-10 are complementary and together they form the WHO Family of International Classifications.

ICD-10 provides a “diagnosis” of diseases, disorders or other health conditions, and it is enriched by ICF, which provides additional information on functioning.

Together, information on diagnosis (ICD-10) plus functioning (ICF) provides a broader and more meaningful picture of health of people or populations and allows more rational allocation decisions and evidence-based policy making.

ICF provides a detailed classification with definitions:

icf is the international standard for health and disability related data and serves as the reference text for the conceptualization of health of health. ICF is recommended for use:

In view of the differing needs of different types of users, ICF is presented in multiple formats and versions:


ICF Full Version

A conclusive volume with glossary definitions and the full list of codes including all details. Available in all official WHO languages (Arabic, Chinese, English, French, Russian and Spanish).


ICF Pocket Version

The pocket sized version contains main 2 level codes (max. 99 per list) for practical purposes. Available in English only.


ICF on CD-ROM

The Cd-Rom includes ICF in six official WHO and other languages and provides the following functionalities:

  1. Allows browsing the classification in its tree structure
  2. Can display two languages at the same time
  3. Provides advanced search functions
  4. Cross-references via hyperlinks
  5. Allows the user to select and work on subets of the classification
  6. Internet-based upgrading facility which allows incorporating future modifications in the classification and additional language versions
  7. Allows user to send comments and feedback to WHO

This book evaluates the risks to human health posed by disinfectants and disinfectant by-products found in treated drinking-water. Noting that chlorine and other widely-used disinfectants were approved for use almost 100 years ago, when toxicological data were limited, the report responds to the need for reassurance that consumption of treated drinking-water will not have adverse effects on health. Particular concern centres on the potential of chlorine to react with natural organic matter and form a large number of by-products, some of which have been intensively studied as potential human carcinogens. With these concerns in mind, the report evaluates over 800 recent studies in an effort to clarify understanding of the chemistry and toxicology of disinfectants and disinfectant by-products, and provide a balanced assessment of the associated risks to human health.

The report is issued at a time when public health authorities and utilities providers in several countries are considering alternative methods of disinfection aimed at reducing the formation of specific by-products. In this context, the report stresses the overriding importance of microbiological safety, and warns that adequate disinfection must not be compromised by efforts to control chemical by-products.

The first chapter, on the chemistry of disinfectants and disinfectant by-products, examines the many complex factors, including methods of water treatment, that govern the formation of by-products and influence their type and amount. Of special interest to utilities providers, the chapter explains the physical and chemical properties that influence the behaviour of specific by-products in drinking-water and determine their toxic actions. By-products of greatest concern are identified as trihalomethanes, including chlororoform and bromodichloromethane, haloacetic acids, including dichloroacetic acid and trichloroacetic acid, bromate, and chlorite. The chapter concludes that the adoption of alternative disinfecting chemicals often amounts to nothing more than a trade-off between one group of by-products and another. Removal of natural organic matter is singled out as the most effective control strategy.

Chapter two reviews what is known about the toxic effects of the principal disinfectants: chlorine and hypochlorite, chloramine, and chlorine dioxide. On the basic of this evaluation, the report concludes that disinfectants probably do not increase the risk of cancer or have other significant adverse effects on health. Chapter three evaluates the toxic effects of fourteen by-products, concentrating on the large number of studies of carcinogenicity and mutagenicity.

Epidemiological studies are reviewed in chapter four, which considers extensive investigations of possible associations with cancer, cardiovascular disease, and adverse effects on reproduction and development. While most studies have concentrated on an increased risk of bladder cancer, risks of colon, rectal, and other cancers have also been investigated. Noting the uncertainties surrounding many of these studies, the report cautions against a simple interpretation of observed associations and concludes that more comprehensive water quality data must be collected to improve exposure assessments. Evidence was considered insufficient to determine whether observed associations are causal and which specific by-products or other contaminants play a role.

In the final chapters, focused on risk characterization and assessment, the report concludes that the risks to health from disinfectant by-products, at the levels at which they occur in drinking-water, are extremely small in comparison with the risks associated with inadequate disinfection. In supporting efforts to minimize the formation of by-products, the report further concludes that protection of source waters, aimed at reducing the presence of natural organic matter, is often the most efficient approach to control.
