Description: The emergence of global avian influenza highlighted the value of a multisectoral, multidisciplinary approach, with the significant risks to humans being managed through effective interventions in poultry and in understanding of the role of wild birds as reservoir species. This required collaboration across very distinct sectors of agriculture, wildlife biology, and human health and, in many countries, paved the way for the adoption of a One Health approach across Government and in research, policy development, and field activities.
