Within the framework of World Health Day, the One Health Mx Institute joins the international interest in generating knowledge, dialogue and actions under the 'One Health' approach. In this commemoration, experts from human, animal and environmental health meet in an exchange of ideas regarding the challenges of health and the 'One Health' approach as a comprehensive response to address and solve these problems. In the same way, we hope that this virtual event generates doubts, innovative ideas and links between different actors in order to improve health conditions at local and international level.
