Worldwide many infectious diseases are passing between animals and humans, while food production, human diet and community stability are harmed by diseases that infect livestock and wildlife, also the political and demographic changes in our population, as well as dynamic changes in animal and vector populations and the environment. As a result, the rapidly growing problem of emerging infections requires new and creative means for prevention and control. However, since the incidence of emerging infectious disease is related to many of the above-mentioned factors, activities to reduce their occurrence are often complex and controversial. It promotes a “whole of society” treatment of health hazards and a systemic change of perspective in the management of risk.

The principles of One Health provide an effective approach for dealing with problems related to the human-animal-ecosystem interface. In this course, the approach is applied to emerging, re-emerging, high impact infectious diseases of humans and livestock and of course trade, food safety and occupational health issues.

One Health recognizes that health of people is connected to the health of animals and the environment and vice versa. That is why its approach in research is interdisciplinary and collaborates between physicians, veterinarians, epidemiologists, microbiologists and ecologists. One Health professionals and students assess public health threats by studying and conducting research about how and why diseases spread among people, animals, and the environment, and contribute to help prevent infectious and non-infectious diseases related to the cohabitation of our world.
