In essence, the One Health concept represents a visionary paradigm shift for health and health care (for humans and animals) by promoting interdisciplinary communications and by co-equal and respectful collaborations for more expeditious public health (infectious diseases) and comparative biomedical investigations, research and discoveries. This is intended to be all-inclusive among the scientific disciplines of human medicine, veterinary medicine and all other related scientific health disciplines. This reprinted Opinion piece, 'One Health…or some health?' highlights a potentially serious disconnect within the One Health movement viz. the trend towards excluding the One Health comparative medicine research and clinical advances resulting from the utilisation of One Health principles. The view that including this critical aspect of One Health endeavours may unduly detract from international public health considerations is short-sighted and deleterious to the promotion of health in its broadest sense.
