Veterinary epidemiology:

The concept of veterinary epidemiology had been established in 1960s. It has come a long way during the last 50 decades in interacting with other disciplines. This study describes the initial history of veterinary epidemiology, contribution to the progress of veterinary science, trend of research including surveillance and epidemiological tools, and the perspectives. The epidemiological approach should stay collaborative, interdisciplinary and trans-sectional as it has been developed on the basis of multiple causation theory. The convergence of the One Health and the Ecohealth must be one way for the veterinary epidemiology to go in the near future.
