Epidemiology of jellyfish stings reported to poison centers in Texas.

This study examined the relationship between selected factors and all human exposures involving jellyfish stings reported to Texas poison centers. Cases were obtained retrospectively from calls to poison centers in Texas and included all reported human exposures during 1998-2004 involving jellyfish stings. The distribution of cases was determined for a variety of demographic and clinical parameters. There were 423 total cases. Among the cases with a known patient age, 19.8% were <6 years of age, 53.5% were age 6-19 years, and 26.7% were >19 years of age. Males accounted for 52% of the cases. Of the 118 cases with a known clinical outcome, 0.8% had no effect, 80.5% had minor effects, and 18.6% had moderate effects. Counties along the Gulf Coast accounted for 72.3% of the calls. This information can be used to identify those portions of the population most at need of education regarding the prevention and treatment of jellyfish stings.
