Abstract
This is a descriptive, retrospective study using a quantitative approach based on secondary data from records related to scorpion envenomation from the Notifiable Diseases Information System (SINAN – Sistema de Informacao de Agravos de Notificacao) from 2004 to 2014. The goal was to determine the frequency of scorpion envenomation in the eight territories of the state of Sergipe and to examine spatial differences and environmental influences on envenomation. The study was conducted in the state of Sergipe, Brazil and analysed the relationship between locations most affected by scorpion stings and anthropogenic changes. The following variables were analysed: month and year of the envenomation, territory, area of the envenomation and population according to Brazilian Institute Geography and Statistics (IBGE - Instituto Brasileiro de Geografia e Estatistica). Territorial changes were observed in the neighbourhood of Santos Dumont, in the municipality of Aracaju, that were caused by human occupation in the years 2003, 2009 and 2014. To analyse the climatic influences on the frequency of scorpion stings, we used the normal temperature and normal rainfall in the municipalities of Sergipe, especially in Caninde de Sao Francisco, Nossa Senhora das Dores and Aracaju, provided by the National Institute of Meteorology and Technology (INMET – Instituto Nacional de Meteorologia e Tecnologia). A total of 8021 accidents with poisonous animals occurred in Sergipe between 2004 and 2014, of which 5133 (63.99%) involved scorpions; 80% of scorpion envenomation in Sergipe occurred in urban areas, with significant differences in the distribution per zone between the territories (P<0.01). The territory of Grande Aracaju (87.9%) had the highest frequency on scorpion envenomation in urban areas, Alto Sertao (55.9%) had the highest frequency in rural areas, and the municipality of Aracaju had 58.11% of all cases of scorpion stings in Sergipe. The neighbourhood of Santos Dumont was the most affected in the municipality of Aracaju, with 219/2983 cases. Regarding preventive measures aimed at the population, it is recommended that individuals maintain cleanliness in the vicinity of their households, avoid accumulating construction waste, use wall coatings, use protective screens in drains and sewers, and seal septic tanks; individuals may also preserve the scorpions’ predators.
Highlights
Scorpion stings are an important public health problem in tropical and subtropical countries.In Brazil, the prevalence of cases is concentrated in the southeast, though there has been a significant increase in cases from the northeastern states, Bahia, Rio Grande do Norte, Pernambuco, Alagoas and Ceará (BARROS et al, 2014 ).In Sergipe, scorpion stings have increased in the last decade

Scorpion stings are an important public health problem in tropical and subtropical countries. In Brazil, the prevalence of cases is concentrated in the southeast, though there has been a significant increase in cases from the northeastern states, Bahia, Rio Grande do Norte, Pernambuco, Alagoas and Ceará (BARROS et al, 2014 ). In Sergipe, scorpion stings have increased in the last decade. This may be related to the modification of territories as described by Mesquita et al (2015), who suggest that urban sprawl increases the accumulation of debris and garbage near houses, increasing the risks of scorpion proliferation. Accidents in rural areas are assumed to be related to the destruction of natural areas for the exploitation of agribusiness. Accidents in rural areas are assumed to be related to the destruction of natural areas for the exploitation of agribusiness. Wagatsuma et al (2003) noted that intensive deforestation, with the substitution of planted areas, has devastated the regions of native forests and caused changes in local, regional and global environmental and climatic factors, such as temperature, soil moisture, and air
