E/C.12/2000/4 page 10 Specific legal obligations 34. In particular, States are under the obligation to respect the right to health by, inter alia, refraining from denying or limiting equal access for all persons, including prisoners or detainees, minorities, asylum seekers and illegal immigrants, to preventive, curative and palliative health services; abstaining from enforcing discriminatory practices as a State policy; and abstaining from imposing discriminatory practices relating to women’s health status and needs. Furthermore, obligations to respect include a State’s obligation to refrain from prohibiting or impeding traditional preventive care, healing practices and medicines, from marketing unsafe drugs and from applying coercive medical treatments, unless on an exceptional basis for the treatment of mental illness or the prevention and control of communicable diseases. Such exceptional cases should be subject to specific and restrictive conditions, respecting best practices and applicable international standards, including the Principles for the Protection of Persons with Mental Illness and the Improvement of Mental Health Care.24 In addition, States should refrain from limiting access to contraceptives and other means of maintaining sexual and reproductive health, from censoring, withholding or intentionally misrepresenting health-related information, including sexual education and information, as well as from preventing people’s participation in health-related matters. States should also refrain from unlawfully polluting air, water and soil, e.g. through industrial waste from State-owned facilities, from using or testing nuclear, biological or chemical weapons if such testing results in the release of substances harmful to human health, and from limiting access to health services as a punitive measure, e.g. during armed conflicts in violation of international humanitarian law. 35. Obligations to protect include, inter alia, the duties of States to adopt legislation or to take other measures ensuring equal access to health care and health-related services provided by third parties; to ensure that privatization of the health sector does not constitute a threat to the availability, accessibility, acceptability and quality of health facilities, goods and services; to control the marketing of medical equipment and medicines by third parties; and to ensure that medical practitioners and other health professionals meet appropriate standards of education, skill and ethical codes of conduct. States are also obliged to ensure that harmful social or traditional practices do not interfere with access to pre- and post-natal care and family-planning; to prevent third parties from coercing women to undergo traditional practices, e.g. female genital mutilation; and to take measures to protect all vulnerable or marginalized groups of society, in particular women, children, adolescents and older persons, in the light of gender-based expressions of violence. States should also ensure that third parties do not limit people’s access to health-related information and services. 36. The obligation to fulfil requires States parties, inter alia, to give sufficient recognition to the right to health in the national political and legal systems, preferably by way of legislative implementation, and to adopt a national health policy with a detailed plan for realizing the right to health. States must ensure provision of health care, including immunization programmes against the major infectious diseases, and ensure equal access for all to the underlying determinants of health, such as nutritiously safe food and potable drinking water, basic sanitation and adequate housing and living conditions. Public health infrastructures should provide for sexual and reproductive health services, including safe motherhood, particularly in rural areas. States have to ensure the appropriate training of doctors and other medical personnel, the provision of a sufficient number of hospitals, clinics and other health-related facilities, and the
