Global health is a very institutionalized field of governance, with diverse international institutions contributing in various ways to promote and protect human health (or negatively affecting it, depending on whom you ask). Such institutions include global international organizations such as the United Nations (UN) and the World Health Organization (WHO), regional organizations such as the European Union (EU), hybrid institutions comprising public agencies and corporate bodies such as the International Standardization Organization (ISO) and, more recently, public-private partnerships and networks showing a similar structure. This proliferation is not surprising conceptually if we consider that health is an intrinsic and essential dimension of human beings and communities, both from a biomedical point of view as well as from a public health and social perspectives. So many transnational factors, processes and policies have a direct or indirect impact on health that not only existing international organizations have integrated or upgraded health considerations in their agendas, but new ones have been established to address neglected aspects of global health governance.
