One Health is an emerging paradigm in public and veterinary health which recognizes that human, animal and environmental health are interlinked. The course will address food and water safety, the increase in prevalence of antibiotic resistant organisms, emerging infectious zoonotic diseases, environmental protection and environmental sustainability, emphasizing the interaction of these diverse yet interconnected disciplines in protecting the health of populations. Lectures are the same as for SPH 416, but with additional assignments and evaluation appropriate to graduate studies. Note: Credit may not be obtained for both PHS 516 and SPH 516. Credit will only be given for one of AFNS 416, 516 or SPH 416, 516. Prerequisite: consent of Instructor.
