Infectious Diseases - 
Excellence in Clinical Care, Research, and Teaching

Activities within the Division of Pediatric Infectious Diseases include the delivery of cutting-edge patient care, biomedical and clinical research in childhood infections and microbial pathogenesis, and teaching of fellows, residents, and students.  The ID division received the Outstanding Division Teaching Award from the St. Louis Children's Hospital residents in 2016, 2017, and 2018.  Division faculty oversee the antimicrobial stewardship, infection prevention, and immunocompromised ID programs at St. Louis Children's Hospital.  Our faculty and fellows also participate in a number of programs and activities with the Division of Infectious Diseases in the Department of Medicine and with the Department of Molecular Microbiology.   Fellowship training in the Division is supported in part by our NIAID T32 training grant in childhood infections and immunity.
