Age-adjusted fatality rates are higher in cold and mountainous Midwestern and Western states and peak in the winter months. In addition, hurricanes and other natural disasters that result in power outages can lead to a spike in CO poisonings, as those affected turn to alternative sources of fuel or electricity. [17] For example, multiple incidents of CO poisoning were reported in Southern states following the Katrina and Rita hurricanes of 2005, in Northeastern states following Hurricane Sandy in 2012, and in Florida following Hurricane Irma in 2017. [18, 19, 20] The Centers for Disease Control and Prevention has established a Web page providing clinical guidance for carbon monoxide (CO) poisoning after a disaster.
