One Health: An Increasingly Popular Approach to Wicked Global Health Problems

Food safety, antimicrobial resistance, and emerging diseases are public health problems found in every country of the world. Such problems often require the collaboration of public health, veterinary health, environmental health, and agricultural business professionals in their prevention and control. Increasingly, due to modern transportation and agricultural techniques, once local or regional public health problems are now often international in scope, affecting thousands of people and animals. We must find ways to work across disciplines and across geographical borders to prevent and control these problems. Many organizations have embraced the One Health approach as the best way forward in developing the necessary multidiscipline and international collaborations. Dr. Gray will discuss the need for adopting the One Health approach in better controlling these complex problems, especially as it pertains to emerging infectious diseases. He will also review his teams’ One Health training programs and research projects at the human-animal interface.  Finally, he will propose some strategies for professionals and trainees to engage in One Health training, research, and employment.
