The right to health is the economic, social and cultural right to a universal minimum standard of health to which all individuals are entitled. The concept of a right to health has been enumerated in international agreements which include the Universal Declaration of Human Rights, International Covenant on Economic, Social and Cultural Rights and the Convention on the Rights of Persons with Disabilities. However, there remains some international variation in the interpretation and application of the right to health due to considerations such as how health is defined, what minimum entitlements are encompassed in a right to health, and which institutions are responsible for ensuring a right to health.
