Disease outbreak response: why epidemiology plays a central role.

The need to control transboundary animal disease outbreaks is widely recognised, as is the need for evidence-based decisions regarding which control measures to implement. Key data and information are required to inform this evidence base. To ensure effective communication of the evidence, a rapid process of collation, interpretation and translation is required. This paper describes how epidemiology can provide the framework through which relevant specialists can be engaged to this end, and highlights the central role of epidemiologists, with their unique combination of skills, in this process. It provides an example of an evidence team led by epidemiologists, namely the United Kingdom National Emergency Epidemiology Group, which was established to address this need. It then goes on to consider the different strands of epidemiology, the need for a wide multidisciplinary approach, and the importance of training and preparedness activities to facilitate rapid response.
