Welcome to The Host Response, a FirstCallID podcast for clinicians navigating the uncertainties of infectious diseases. In this opening episode, Dr. Paul Bunce introduces the mission behind FirstCallID — to help clinicians feel more grounded, confident, and less overwhelmed when facing ID questions. Unlike the structured teaching tools on the website, this podcast offers space for reflection, clinical insight, and honest conversations about the messiness of real-life decision-making. Whether you're early in training or decades in, you're not alone in the grey zone.
