Genomic epidemiology is reshaping how we detect, investigate, and control infectious disease outbreaks—but what does that actually look like from the bench to public health? In this episode of Let's Talk Micro, Luis is joined by genomic epidemiologist Krisandra Allen for a practical, case-based conversation on how pathogen sequencing data is generated, analyzed, and paired with epidemiologic information to answer questions traditional methods can't. They discuss foodborne and hepatitis A outbreaks, geographically dispersed clusters, and how sequencing is being integrated into routine public health workflows, while highlighting the essential role of clinical microbiology labs in specimen submission and data quality. A timely episode for microbiologists, public health professionals, and trainees curious about how their lab work feeds into real-world surveillance and outbreak response.
