The World Health Organization's (WHO) Constitution affirms, in its preamble, a fundamental and non-discriminatory right to health and health care. In doing so, it echoes a number of widely ratified treaties and other international legal instruments with a strong claim to having the status of customary international law, including the International Convention on the Elimination of All Forms of Racial Discrimination, the International Covenant on Economic, Social and Cultural Rights (ICESCR), the Convention on the Elimination of All Forms of Discrimination Against Women, the Universal Declaration of Human Rights, the Convention on the Rights of the Child, the ILO Convention on Indigenous and Tribal peoples in Independent Countries, and the Standard Minimum Rules for the Treatment of Prisoners. Most recently, the Institut de Droit affirmed that same fundamental right in Article 4 of its September 2021 Resolution on Epidemics, Pandemics, and International Law.
