How did international agencies perceive the avian influenza problem? The adoption and manufacture of the ‘One World, One Health’ framework

Over the past few years, a ‘One World, One Health’ (OWOH) policy framework has become the guiding principle for international responses to avian influenza and other zoonotic infectious diseases. Several specialised inter‐governmental agencies, including the World Health Organization, the Food and Agricultural Organization and World Organization for Animal Health, jointly endorsed and promoted this framework. This article attempts to explain why international agencies advocated OWOH despite its vagueness. By examining how these international agencies gradually reframed avian flu problems, this article illustrates the crucial roles of international agencies in constructing disease knowledge and relevant policy responses. It shows that the three agencies adopted an all‐inclusive approach to reduce conflicts, defend their legitimacy, and facilitate commitment for collaboration. Not only has this new framework reduced tensions between agencies, it has also reshaped the interests and interactions of other global actors. The case thus illustrates how these organisational actors actively manufacture new cognitive frames and policy regimes that advance their own legitimacy and influence.
