Cooperation between veterinary and public health authorities in Bosnia and Herzegovina and their respective field services has historically been weak and inefficient. As is the case in many countries, animal health and public health fall under separate ministries with animal health the responsibility of the ministry of agriculture and public health the ministry of health. This model has promoted interagency competition for funding for disease surveillance and control. It has also resulted in poor information exchange, lack of efficient utilization of diagnostic resources, and poor harmonization of policies. Political decentralization, established in Bosnia after the Dayton peace agreement, resulted in the lack of a national-level responsibility for animal or public health. This was instead placed at mid-governmental levels. A state (national) veterinary office was created in 2000, but there still remains no national public health agency. The H5N1 Avian Influenza (AI) outbreak which began in Southeast Asia in 2003 and reached Europe in 2005 raised concerns about Bosnia and Herzegovina's (BiH) preparedness to combat pandemic disease. Accordingly, the state (national) veterinary service of Bosnia and Herzegovina (BiH) conducted exercises which resulted in increased monitoring of wild and domestic bird populations and the drafting and adoption of a contingency plan (CP) for AI. The activities prescribed by the CP were implemented in February 2006 when the H5N1 virus was diagnosed in wild swans. However, no cooperation was established with public health authorities during this incident, further underscoring the need for a one health approach to disease control activities. Adoption of the One Health concept is challenging, and there is no simple plan that can be applied across all cultures. To prevent it from simply existing as an idealistic theory, some revision is needed and practical guidelines must be developed. The authors will include suggestions as to how this might be achieved.
