The One world, One health concept focuses on the current and potential movements of diseases among human, domestic animal and wildlife populations. Human, animal and ecosystem health are inextricably linked and a paradigm shift in approaching infectious and non-infectious diseases of humans and animals is essential to meet the challenges of the 21st century resulting from globalisation, climate change and population growth. Cooperation and collaboration between medical, veterinary, public health, environmental and ecosystem professionals is essential in effective research leading to the control of zoonotic disease.
Between animal and human medicine there is no dividing line—nor should there be. The object is different but the experience obtained constitutes the basis of all medicine.” Rudolf Virchow (1821–1902)
