'One Medicine - One Health' interview with Ronald M. Davis, MD, President of the American Medical Association, 14 May 2008.

A brief account is presented of the unique historical background leading up to the American Medical Association (AMA) adopting a landmark 'One Health' resolution in June 2007. The historic 'One Health' liaison between the American Veterinary Medical Association (AVMA) and AMA was fostered by collaboration between Roger Mahr and Ron Davis when they were both serving as Presidents of their respective organisations. This cooperative relationship resulted in what has been referred to as the 'One Health initiative' in the United States. National and global implementation is the goal.
