Ellie's background in microbiology and public health shaped her career in infection prevention. Building a laboratory network in Indiana was a significant project that enhanced public health. Infection preventionists play a crucial role in managing outbreaks in healthcare settings. Genomic sequencing is becoming increasingly important in identifying and controlling infections. Current outbreak detection methods in healthcare are often limited and retrospective. APIC 2024 highlighted the potential of genomic epidemiology in healthcare. Cost-effectiveness is a key factor in adopting genomic sequencing in hospitals. Challenges include financial investment and the need for bioinformatics expertise. Healthcare systems must learn from public health to implement genomic sequencing effectively. The ultimate goal is to prevent harm to patients through better infection control practices.
