Epidemiology of Scorpionism in Iran during 2009

Scorpion sting is a major health problem in Iran. The aim of current study was to measure the inci­dence rates of scorpion stings, mortality, recovery, and affected age groups. The results of treatment with and with­out anti venom also were considered in the entire country during 2009. All the data were collected from emergency section of different hospitals and then were analyzed by re­lated software. The responsibility of such data collection and surveillance is related to the Department of Violence and Injury, Ministry of Health and Medical Education of Iran. A total incidence of 59.5/100000 was found for the 12-month period. During the study period the most and the least cases were reported from Khuzestan and Mazandaran provinces with incidence of 541 and 0 per 100000 respectively. Totally 40220 anti venom vials were used, i.e., the ratio of 91 vial/ 100 affected cases. The stings occur mainly in rural areas (57.7%). Young people with the age group of 15–24 years old were the most victims of stings. The mortality and recovery rates of cases who had received anti venom less than 6 h of stings were calculated as 0.01% and 99.9% respectively. The high incidence of scorpion stings in Iran especially in Khuzestan suggests the necessity of preven­tive programmes for decreasing the incidence. Such programmes could start by community educating in the high prevalent areas. In addition prompt and local treatment is particularly important for infants and pre-school children.
