AG724Paravetrinary & One Health (AGRO)NIL115
Traditional health initiatives generally tackled health issues in isolation to other disciplines as if they were not related. For example, previously in the field of animal health, human health or environmental health, there had been very little collaboration and communications between these disciplines. However, nowadays, these disciplines are no longer isolated because one affects the other, thus combining them into a one health concept. For example, animal diseases are no longer restricted to animals because more 60% of human diseases had their origins from animals (One health, Wikipedia, September 2015). Not only that but what constitutes the environment will determine the health of living being connected to that environment. As such the health of animals, human beings and the environment has to be treated and approached in a holistic manner, thus the evolution of “One health” concept.
