One Health can be defined as a global concept of promoting human health based on a strategy for a better comprehension of the current health issues created by the interactions of human, animal and environment domains. In fact, this global concept of promoting health is not new: this approach was proposed by William Osler and Rudolf Virchow, and enhanced by Calvin Schwabe’s in the 1984 published book “Veterinary Medicine and Human Health”1. Considering the growing interdependence between human and animals, mainly due to their food products, the medical and veterinarian professions have been directed to work together, under this collaborative approach. As result, this approach stimulates collaborative studies between related groups, and mainly between science institutes from distinct regions and countries, to achieve optimal health for people, animals and the environment. This collaborative approach results in several benefits, such as:

• Improvement of animal and human health;
• Meeting new challenges that can be deal with the collaboration among professionals from veterinary medicine, human medicine, environmental, wildlife and public health;
• Development of excellence centers for education and training, enhancing the collaboration between scientific groups of veterinary medicine, human medicine, and public health;
• Increase professional opportunities for physicians and veterinarians;
• Enhancing the scientific knowledge to create innovative programs to improve health.
