The field of zoonotic and emerging infectious diseases is the most obvious example of the association between humans, animals and their environments. As a result of an increasing recognition of the importance of these relationships, One Health has come to represent an unified theoretical framework under which physicians, veterinarians, public health officials, epidemiologists, biomedical researchers, ecologists, water quality experts, and many others, collaborate to more fully understand the complex relationships that contribute to overall health and disease.

Whilst One Health is an emerging field, it has its roots in Classical Greek thought, going back to Hippocrates in his work “Concerning Air, Water, and Places”. Hippocrates begins his book by pointing out that if anyone wants to practice medicine properly, then they need to take a number of factors into consideration. These include the nature of the seasons, the winds and temperatures of a locality, the quality of the waters of an area, the temperament and situations of the people and animals that live in an area, and even the practices of the people and animals. It is only once all of these factors are taken into consideration that one can “ὀρθῶς ζητεῖν” or “heal correctly”.
