Welcome to our free open-access medical education (FOAMed) resource in infectious diseases, managed by Infectious Disease Fellowship Program co-directors, Gerome Escota, MD and Ige George, MD, MSc, both assistant professors of medicine. Together they created a Twitter-based platform, @WuidQ: Washington University ID Questions, which is the first free, open-access medical education resource to provide review of infectious diseases through board-style, multiple-choice questions.
