Jakob Zinsstag is the author of a comprehensive textbook on One Health presenting necessary and sufficient criteria to fulfill a One Health approach. One Health as a problem-solving concept combining research and public health action in an iterative process. To fully understand the range of potential benefits implies a deeper and comprehensive recognition and understanding of how humans and animals and their environment are interrelated. Equally important, it requires a demonstration and documentation of the benefits and added values resulting from the cross-talk and closer cooperation between human and animal health. One Health can thus be defined as any added value in terms of health of humans and animals, financial savings or environmental services achievable by the cooperation of human and veterinary medicine when compared
to the two medicines working separately (Zinsstag 2015).
