Scorpion sting accidents are a public health problem in Belo Horizonte and veterinarians play an important role in its control program when based on capture, mapping of cases and educational actions with the population. A retrospective epidemiological study was done to analyze the frequency and spatial distribution of scorpion sting cases in Belo Horizonte, between 2005 and 2009, and to associate them with the Health Vulnerability Index (IVS), a regional and composed socio-economic index. Notification data of scorpion sting accidents were used from the National System of Notifiable Diseases (SINAN) and Epidemiological Surveillance System (SISVE) for years 2008 and 2009. For the period between 2005 and 2007 it was necessary to retrieve data from the clinical records of João XXIII Hospital (HPSJ XXIII) which were not digitalized in the referred information systems. For georeference and spatial analysis, geographic base EndGeo and features of the programs MapInfo version 10.0, Hotspot Detective and SatScan were used. Between 2005 and 2009 2769 cases of scorpionism, occurred in Belo Horizonte which represents an average incidence of 22.4 cases per 100,000 inhabitants. Among 1924 (69.5%) georeferenced cases, the highest incidence was observed in two Sanitary District (DS). A large concentration of cases was also observed in the areas of the city cemeteries. Two clusters were detected during this period, one in 2005, located in the Northwest and West DS, and another between 2006 and 2007 in the Northwest and Northeast DS. There was no association between higher incidence areas of scorpionism in Belo Horizonte and the areas of higher health risk classified by IVS. It is necessary to improve the reporting process regarding scorpion sting accidents. Another conclusion is that the mapping of cases is a relevant tool to base the targeting of educative actions to the priority areas of Belo Horizonte.
