“…This may explain the greater frequency of envenomation affecting the extremities of the victim’s body. In the present study, the body areas most affected by the stings were the foot and the hand, totaling 76.65% of the cases, confirming the results reported by other authors 19 , 28 , 39 . However, the sting in the torso area has a risk of death 6.56 times higher than the other anatomical regions (1,848-23,300; p <0.05), showing that the anatomical region of the body affected by the sting may be an important factor for the severity and progression of the case.…”

“…This uniform monthly distribution of the cases may be related to the stable climate conditions of the studied region, which is characterized by high temperatures in all months of the year and a low rainfall index 18 . Stable climate conditions favor the activity and reproduction of scorpions, which can contribute to increase the number of cases in Northeastern Brazil 19 . On the other hand, in the South and Southeast of Brazil, the incidence of stings seems to be related to seasonal factors.…”

This communication is a retrospective epidemiological study of the scorpion sting cases recorded from 2007 to 2014 in the Rio Grande do Norte State, Northeastern Brazil. The data was collected from the Injury Notification Information System database of the Health Department of Rio Grande do Norte State. A total of 20,555 cases were studied. The cases were distributed over all months of the period studied and occurred mainly in urban areas. Victims were predominantly 20-29 year-old women. Most victims were stung on the foot and received medical care within 1-3 h after being stung. The cases were mostly classified as mild and progressed to cure. Scorpion stings in Rio Grande do Norte State are an environmental public health problem that needs to be monitored and controlled throughout the year.

“…Scorpion stings show greater severity in childhood, suggesting that there is a direct relationship between venom levels in the plasma and the poisoning severity [ 34 ] by which venom would reach higher plasma concentrations in children due to their lower body mass [ 9 ]. Similar results were found in other parts of Brazil [ 35 , 36 ], Mexico [ 10 ], Colombia [ 37 ] and Argentina [ 38 ]. In this study, lethality rate among children ≤10 years was 1.3%, four times higher than in the general population, showing scorpion stings as a cause of death among children in the Brazilian Amazon.…”

Severity of Scorpion Stings in the Western Brazilian Amazon: A Case-Control Study

et al. 2015

BackgroundScorpion stings are a major public health problem in Brazil, with an increasing number of registered cases every year. Affecting mostly vulnerable populations, the phenomenon is not well described and is considered a neglected disease. In Brazil, the use of anti-venom formulations is provided free of charge. The associate scorpion sting case is subject to compulsory reporting. This paper describes the epidemiology and identifies factors associated with severity of scorpions stings in the state of Amazonas, in the Western Brazilian Amazon.Methodology/Principal FindingsThis study included all cases of scorpion stings in the state of Amazonas reported to the Brazilian Diseases Surveillance System from January 1, 2007 to December 31, 2014. A case-control study was conducted to identify factors associated with scorpions sting severity. A total of 2,120 cases were reported during this period. The mean incidence rate in the Amazonas was 7.6 per 100,000 inhabitants/year. Scorpion stings showed a large spatial distribution in the state and represent a potential occupational health problem for rural populations. There was a positive correlation between the absolute number of cases and the altimetric river levels in the Central (p<0.001; Rs = 0.479 linear) and Southwest (p = 0.032; linear Rs = 0.261) regions of the state. Cases were mostly classified as mild (68.6%), followed by moderate (26.8%), and severe (4.6%). The overall lethality rate was 0.3%. Lethality rate among children ≤10 years was 1.3%. Age <10 years [OR = 2.58 (95%CI = 1.47–4.55; p = 0.001)], stings occurring in the rural area [OR = 1.97 (95%CI = 1.18–3.29; p = 0.033) and in the South region of the state [OR = 1.85 (95%CI = 1.17–2.93; p = 0.008)] were independently associated with the risk of developing severity.Conclusions/SignificanceScorpion stings show an extensive distribution in the Western Brazilian Amazon threatening especially rural populations, children ≤10 in particular. Thus, the mapping of scorpions fauna in different Amazon localities is essential and must be accompanied by the characterization of the main biological activities of the venoms. Urban and farming planning, in parallel with awareness of workers at risk for scorpion stings on the need for personal protective equipment use should be considered as public policies for preventing scorpionism.

“…Females in this setting might have greater exposure related to domestic activities, such as cleaning of places that often serve as shelter for scorpions, such as sinks, bathroom drains, clothing and shoes. 7 Nevertheless, other studies have pointed out higher occurrence of male scorpionism. 9 Activities performed outside the home, especially those relating to construction and agriculture, have been reported to be related to scorpion accidents.…”

BACKGROUND: Scorpion accidents have gained great visibility around the world because of the high frequency and severity with which they occur, and have become a global medical-sanitary problem. OBJECTIVE: The aim of this study was to describe the sociodemographic, clinical and epidemiological profile of scorpionism in the municipality of Jequié, Bahia, Brazil, from 2007 to 2015. DESIGN AND SETTING: Retrospective epidemiological study in the municipality of Jequié, Bahia, Brazil. METHODS: This study was based on data collected from the epidemiological investigation notification forms of the injury information system. RESULTS: There was an increase in the coefficient of incidence of scorpion accidents in Jequié from 23.4/100,000 in 2007 to 413.6/100,000 in 2015. There were 3565 cases: 54.9% were female, 58.8% were aged 20-59 years, 63.5% had brown skin color and 48.6% had incomplete primary education. Most accidents occurred in urban areas (93.1%). Homes were the main place of occurrence (84.5%) and upper limbs were the commonest sting sites (53.0%). Regarding clinical aspects, 66.4% of the cases received hospital assistance within one hour after the bite, 84.1% presented mild severity, 97.1% had local manifestations and 10.2% had systemic symptoms. Serum therapy was administered in 17.3% of the cases, and 99.9% evolved to cure. CONCLUSION: There was an increase in the incidence of scorpion accidents in the municipality, which demonstrates the need for investment in actions that reduce the morbidity and mortality caused by these accidents, such as educational campaigns and improvements in socioeconomic and health conditions.
