Epidemiology of Scorpion Sting in Southwestern Iran Over Five Years

Abstract

Background: Scorpionism is a considerable public health problem worldwide in tropical and subtropical regions. It is one of the major health problems and the leading cause of death in the western and southern parts of Iran. Objectives: This study was performed with the aim of investigating the epidemiological features of scorpion stings in Shoushtar city. Methods: This cross-sectional study was performed on 5479 cases in Shoushtar city, Khuzestan province, Iran, from January 1, 2014 until December 31, 2018. First, the incidence rate of scorpion stings was calculated for the study years; then, the bites frequency distribution chart was drawn by month. The t-test and Fisher exact test were used for data analysis using SPSS 22. Results: The average incidence rate of scorpion stinging during the study period was 579.55 per 100000. There was a gradual decrease in the incidence rate over the study period. The incidence of scorpionism was lower in winter, especially in January and February. The most prone body parts of sting were arms and legs (76%); the stings were more common in men than women and more in urban areas than rural areas. Household women had the highest frequency of stings, so almost 1 of every 3 victims was household women; most stings happened indoors. There was a significant association between gender and location, so it was 13 times more in women than men in an indoor location (P = 0.001, OR = 0.076). Conclusions: Shoushtar is a city with a high incidence rate of scorpion sting in the country, especially in the warm seasons. Most cases of stings occur in Housekeepers and in indoor environments. It seems renovation of residential areas, using chemical controls in roofed areas, and enhancing people's knowledge regarding the advantage of using gloves and boots can be vital in the reduction of sting incidences.
