Deaths Related to Hurricane Irma - Florida, Georgia, and North Carolina, September 4-October 10, 2017

Collecting and analyzing mortality data is important for understanding the main circumstances of deaths related to a disaster such as Hurricane Irma. Among deaths attributed to Hurricane Irma, the most common circumstance-of-death categories were exacerbation of existing medical conditions and power outage. Further analysis revealed two unique subcategories of heat-related and oxygen-dependent deaths in which power outage contributed to exacerbation of an existing medical condition. Understanding the need for subcategorization of disasterrelated circumstances of death can help public health practitioners develop more effective public health interventions to prevent deaths in future disasters.
