Morbidity and Mortality Weekly Report

Abstract

This report provided valuable information about the incidence and characteristics of heat illness related to sports and recreation. The Centers for Disease Control (CDC) analyzed data from the National Electronic Injury Surveillance System (NEISS) from 2001 to 2009 and found that approximately 5946 people were treated in a US Emergency Department (ED) each year for heat illness. The NEISS monitors consumer product-related injuries treated in 100 US hospital EDs. Cases were excluded that were not precipitated by natural or environmental causes.
