Epidemiology of scorpion envenomations in Texas.
About 90 scorpion species occur in the US, and scorpion stings accounted for over 15,600 calls to poison centers in the US in 2002. However, epidemiologic information on scorpion envenomations in the US, and Texas in particular, is limited. This study investigated the relationship between epidemiological factors and the scorpion stings reported to the Texas poison centers. Cases consisted of all human exposure calls of scorpion stings to Texas poison centers during 1998-2003; there were 11,545 total cases. The reported scorpion envenomation penetrance increased during 1998-2002. Among cases with a known patient age, 10.9% were < 6 y of age, 21.7% were age 6-19 y and 67.3% were > 19 y of age. Females accounted for 55.8% of the cases and males for 44.2% of the cases. Scorpion stings were most frequently reported in May and June with envenomation penetrance lowest in northeast Texas and highest in west Texas. The exposure site was the patient's own residence for 93.9% of the cases. The management site was not a health care facility for 95.8% of cases, and there were minor effects in 88.4% of cases with a known clinical outcome.
