Law as a fixture between the One Health interfaces of emerging diseases

A One Health approach calls for multisectoral and multi-institutional cooperation and partnership across the interfaces of human, animal and ecosystem health risks. Without strong governance, these interfaces risk detaching, leaving gaps in capacities to prevent, detect and respond to emerging and persisting public health threats. As a crucial component of governance, law can act as the fixture between interfaces. We examine some of the many forms and foci of law and propose that the process of law-making, implementation and evaluation can provide a benefit for strengthening law as a fixture between One Health interfaces. To demonstrate this, we discuss three current examples of international legal instruments for emerging infectious diseases: the International Health Regulations, the Pandemic Influenza Preparedness Framework and the Global Action Plan on Antimicrobial Resistance.
