IMED 2018 will once again bring leading scientists, clinicians and policy makers together in Vienna to present new knowledge and breakthroughs and discuss how to discover how to discover, detect, monitor, understand, prevent, and respond to outbreaks of emerging pathogens. Since its inception, IMED has been a summit that unifies our approach to pathogens in the broadest ecological context. Drawing together human, veterinary, and environmental health specialists, IMED serves as a true One Health forum where those working in diverse specialties and regions can meet, discuss, present and challenge one another with findings and new ideas. As pathogens emerge and mutate, our methodologies for detection, prevention, control, and treatment also continue to evolve. New approaches to vaccination and isolation, the use of novel data sources, genomics, novel laboratory methods, rapid point-of-care diagnostics, risk communication, and political and societal responses to outbreaks have all seen innovation and change that will be explored at IMED 2018.
