The goals of the Division of Infectious Diseases are to provide state-of-the-art care that is easily accessible and responsive to the needs of patients and our clinical colleagues; to rigorously train medical students, residents and graduate students in the discipline of infectious diseases; and to mentor the fellows in our fellowship programs to become the next generation of knowledgeable and respected researchers, clinicians and educators. We do this by developing and performing “cutting-edge” basic and clinical research that translates progress into clinical practice and improves the standard-of-care for treatment and prevention of infectious diseases, and protecting the public health from natural and man-made epidemics of infectious diseases.
