World Health Assembly in the context of "International Health Regulations"

ICD-10 is the 10th revision of the International Classification of Diseases (ICD), a medical classification list by the World Health Organization (WHO). It contains codes for diseases, signs and symptoms, abnormal findings, complaints, social circumstances, and external causes of injury or diseases. Work on ICD-10 began in 1983, was endorsed by the Forty-third World Health Assembly in 1990, and came into effect in member states on January 1, 1993. ICD-10 was replaced by ICD-11 on January 1, 2022.

While WHO manages and publishes the base version of the ICD, several member states have modified it to better suit their needs. In the base classification, the code set allows for more than 14,000 different codes and permits the tracking of many new diagnoses compared to the preceding ICD-9. Through the use of optional sub-classifications, ICD-10 allows for specificity regarding the cause, manifestation, location, severity, and type of injury or disease. The adapted versions may differ in a number of ways; some national editions have expanded the code set even further, with some going so far as to add procedure codes. ICD-10-CM, for example, has over 70,000 codes.

The ICD-11 is the eleventh revision of the International Classification of Diseases (ICD). It replaces the ICD-10 as the global standard for recording health information and causes of death. The ICD is developed and annually updated by the World Health Organization (WHO). Development of the ICD-11 started in 2007 and spanned over a decade of work, involving over 300 specialists from 55 countries divided into 30 work groups, with an additional 10,000 proposals from people all over the world. Following an alpha version in May 2011 and a beta draft in May 2012, a stable version of the ICD-11 was released on 18 June 2018, and officially endorsed by all WHO members during the 72nd World Health Assembly on 25 May 2019.

The ICD-11 is a large ontology consisting of about 85,000 entities, also called classes or nodes. An entity can be anything that is relevant to health care. It usually represents a disease or a pathogen, but it can also be an isolated symptom or (developmental) anomaly of the body. There are also classes for reasons for contact with health services, social circumstances of the patient, and external causes of injury or death. The ICD-11 is part of the WHO-FIC, a family of medical classifications. The WHO-FIC contains the Foundation Component, which comprises all entities of the classifications endorsed by the WHO. The Foundation is the common core from which all classifications are derived. For example, the ICD-O is a derivative classification optimized for use in oncology. The primary derivative of the Foundation is called the ICD-11 MMS, and it is this system that is commonly referred to as simply "the ICD-11". MMS stands for Mortality and Morbidity Statistics. The ICD-11 is distributed under a Creative Commons BY-ND license.

The World Health Organization Framework Convention on Tobacco Control (WHO FCTC) is a treaty adopted by the 56th World Health Assembly held in Geneva, Switzerland on 21 May 2003. It became the first World Health Organization treaty adopted under article 19 of the WHO constitution. The treaty came into force on 27 February 2005. It had been signed by 168 countries and is legally binding in 182 ratifying countries. There are currently 14 United Nations member states that are non-parties to the treaty (eight which have not signed and six of which have signed but not ratified).

The FCTC, one of the most quickly ratified treaties in United Nations history, is a supranational agreement that seeks "to protect present and future generations from the devastating health, social, environmental and economic consequences of tobacco consumption and exposure to tobacco smoke" by enacting a set of universal standards stating the dangers of tobacco and limiting its use in all forms worldwide. To this end, the treaty's provisions include rules that govern the production, sale, distribution, advertisement, and taxation of tobacco. FCTC standards are, however, minimum requirements, and signatories are encouraged to be even more stringent in regulating tobacco than the treaty requires them to be.
