Many types of disasters may potentially affect healthcare, ranging from natural disasters to man-made events. Emergency management is the process by which an individual, facility, and/or community uses mitigation strategies to better prepare for, respond to, and recover from all types of disasters/emergencies and mass casualty events. To accomplish this, an all-hazards approach must be utilized. Emergency management is a multidepartmental, multiagency endeavor that requires coordination and communication among many groups to be most effective. It is essential that infection preventionists participate in all phases of the emergency management process to decrease the mental health impact, costs, morbidity, and mortality related to mass casualty incidents.
