In the past two decades there has been a growing realisation that the livestock sector was in a process of change,
resulting from an expansion of intensive animal production systems and trade to meet a globalised world’s increasing
demand for livestock products. One unintended consequence has been the emergence and spread of transboundary
animal diseases and, more specifi cally, the resurgence and emergence of zoonotic diseases. Concurrent with changes
in the livestock sector, contact with wildlife has increased. This development has increased the risk of transmission of
infections from wildlife to human beings and livestock. Two overarching questions arise with respect to the real and
perceived threat from emerging infectious diseases: why are these problems arising with increasing frequency, and
how should we manage and control them? A clear conceptual research framework can provide a guide to ensure a
research strategy that coherently links to the overarching goals of policy makers. We propose such a new framework in
support of a research and policy-generation strategy to help to address the challenges posed by emerging zoonoses. |
