Dear colleagues,

Welcome at ISVEE; the 13

international symposium on veterinary epidemiology and economics.

Welcome to Maastricht.

Decision makers dealing with animal health problems, at the herd, regional or (inter)national level are increasingly faced with new challenges. New pathogens like the Schmallenberg virus, increasing demand for animal protein in developing countries, climate change, increasing interest in the risks of animals for human health, and increasing questions of the society at large about the way we keep animals are only a few out of many. Veterinary epidemiology and veterinary economics are the scientific disciplines that can help taking the best decision, because they provide crucial quantitative information about animal health at the population level.

Nevertheless, veterinary epidemiology and economics cannot do that alone, because we would just be providing statistical associations from a black box. Only by crossing the border with other disciplines like microbiology, immunology, veterinary and animal sciences, communication and others and by focussing on the bridges that connect them with veterinary epidemiology and economics we can create the multi-disciplinary approach needed to solve many of today’s research questions.

Crossing borders, building bridges is the motto of this symposium and you will encounter this motto throughout the conference, in the keynote lectures as well as in many of the oral and poster sessions. A variety of topics will be presented to you from sophisticated statistical modelling over socio-economic impact of diseases to the application of veterinary epidemiology in daily practice.

Thanks to the many contributions and excellent key note speakers, you will hear state of the art presentations and see posters with top of the bill science originating from over 70 different countries and covering animal health and diseases from a wide variety of species. Sessions and breaks will give you ample opportunities to discuss with your colleagues and, moreover, we are convinced that our attractive social programme will help you expand and strengthen your network.

We encourage you to look, listen and discuss and to build new scientific and personal bridges so that veterinary epidemiology and economics can further flourish in a multi-disciplinary scientific world.

We thank the scientific committee for their invaluable help in designing a very interesting programme. Moreover, we thank our sponsors for making this conference possible. Most of all we thank you, participants of ISVEE, for your contributions and your presence at ISVEE 2012. We wish you an inspiring conference.
