Foundations of Immunology and Infectious Disease provides a fundamental understanding of the principles of immunology and infectious disease, and the application of this knowledge to immunologic, infectious, and rheumatologic diseases. The five-week course integrates immunology through the learning of microbiology and includes relevant aspects of anatomy, histology, pharmacology, and pathology. Specifically, students: (1) learn about the soluble mediators, cells, and organs of the immune system and how these elements work together to prevent infection; (2) examine how the immune system causes and contributes to diseases such as autoimmunity, allergy, and chronic inflammatory diseases; and (3) acquire the necessary foundational knowledge of virology, mycology, parasitology, and bacteriology to understand how infectious microbes cause organ-specific and systemic diseases. Clinical cases are presented in a team-based learning format to provide reinforcement of basic science concepts as they relate to clinical applications. After completing this course, medical students are able to apply the general concepts of immunology and infectious disease to specific diseases they encounter in future organ-based courses.
