One Border One Health   California – Baja California Regional Network (USA and Baja California, Mexico) Mission: One Border One Health is a binational multidisciplinary cooperative building more resilient and healthy border communities by identifying, responding, and creating sustainable solutions to health risks at the human-animal-environmental interface. Since 2011, over 100 professionals from the border states of California, USA and Baja California, Mexico, representing animal & human medicine, public health, agriculture, environmental health, biology, epidemiology, and wildlife health and rehabilitation have come together to develop a model to integrate human, animal, and environmental health activities with a novel binational approach. While collaboration between nations is critical, these collaborative efforts should also cross disciplines.  Human, veterinary and environmental health professionals have not only become increasingly specialized they have also traditionally been institutionally separated, often resulting in inefficiency, duplication of effort, and economically less sustainable programs.  One Border One Health seeks to reconfigure these approaches to move away from species specific programs to more species neutral/pathogen specific programs creating an operationally successful One Health approach.  The ultimate aim is not only to protect border communities but also to create an early warning system which would “shift surveillance to the left” and allow for actionable and timely interventions to limit emergence, mitigate spread and enhance prevention and control and thus decrease negative health, agricultural and economic outcomes.
