World Organisation for Animal Health: strengthening Veterinary Services for effective One Health collaboration.

To effectively reduce health risks at the animal-human-ecosystems interface, a One Health strategy is crucially important to create strong national and regional animal health systems that are well coordinated with strong public health systems. Animal diseases, particularly those caused by new and emerging zoonotic pathogens, must be effectively controlled at their source to reduce their potentially devastating impact upon both animal and human health. As the international organisation responsible for developing standards, guidelines and recommendations for animal health, the World Organisation for Animal Health (OIE) plays an important role in minimising animal and public health risks attributable to zoonoses and other animal diseases, which can have severe consequences for global food safety and security. National Veterinary Services, which implement OIE animal health and welfare standards and other measures, are the first line of defence against these diseases, and must have the capacity to meet the core requirements necessary for their diagnosis and control. The OIE works collaboratively with the World Health Organization and Food and Agriculture Organization of the United Nations to improve the ability of national animal and public health systems to respond to current and emerging animal health risks with public health consequences. In addition to improving and aligning national laboratory capacities in high-risk areas, the OIE collaborates on One Health-oriented projects for key diseases, establishing model frameworks which can be applied to manage other existing and emerging priority diseases. This article reviews the role and activities of the OIE in strengthening the national Veterinary Services of its Member Countries for a more effective and sustainable One Health collaboration.
