This document focuses on making recommendations for the diagnosis and treatment of Chagas disease, an infection caused by Trypanosoma cruzi, the protozoan agent of a systemic parasitic disease. Methodology: These clinical practice guidelines were prepared following the WHO handbook for guideline development (5). A multidisciplinary development group was formed, comprised of thematic experts, epidemiologists, methodologists, and users. Since there were no existing guidelines that could be adapted, the guidelines were developed from scratch.
