An epidemiological description of lightning-related deaths in the United States

To better quantify and update the health impact of lightning and to compare potential sources of information, we reviewed data from the National Centre for Health Statistics (NCHS) database for 1968 through 1985 and from the North Carolina Medical Examiner (NCME) computerized database for 1972 through 1984. We epidemiologically characterized all lightning-related deaths identified in these databases. Results of our analysis are presented together with previously published information from the National Oceanic and Atmospheric Administration and from the National Institute for Occupational Safety and Health. In the US, Wyoming has the highest average annual lightning-related death rate (0.196/100,000), whereas Florida has the largest cumulative incidence of deaths (200) for this 18-year period. Death rates are the highest for males and for people 10-19 years old. There is a tendency toward a slight, but steady, decrease in the yearly incidence of lightning-related deaths. One-third of the fatalities are job-related. Both the NCHS and NCME databases are limited in describing the circumstances and aetiologies of these deaths.
