Chagas Disease: Connections Between Humans, Animals and the Ecosystem
Ashley Saunders, Sarah Hamer, Rachel Curtis, Trevor Tenney, and Jodi Korich

Chagas disease is an infectious disease caused by the parasite Trypanosoma cruzi and transmitted by the kissing bug (triatomine insects). It is a well-known disease affecting humans and animals in South America and is an emerging disease with zoonotic potential that is under recognized in the United States. This case study of a dog diagnosed in the United States aims to leverage technology to enhance students' knowledge and understanding of Chagas disease including the clinical presentation and cardiac manifestations in dogs, when to consider testing for infectious diseases, kissing bug vector ecology and epidemiology, and client education including animal and human health aspects and vector management. The case highlights the One Health initiative to focus attention on the importance of connections between humans, animals and the ecosystem. A web-based case study allows learners to make a series of clinical decisions as they follow a real case from diagnosis through treatment using instructional video lectures and other useful reference materials in an interactive and media rich format.
