However, deaths due to severe envenoming by scorpion stings have not been recorded in Buenos Aires city and suburban regions, although the presence of scorpions in this city has been increasingly reported. We studied the temporal and geographical distribution of Tityus trivittatus findings in Buenos Aires city from the database of the Research and Development Area from the National Institute for Production of Biologics of the National Ministry of Health during the period 10/01/2001 to 31/12/2012 in order to correlate these findings with the distribution of health centers in the city. In this period 385 consults with identification of scorpions were recorded. Annual records showed a growing trend. Georeferenced data showed that findings appeared to increase in the surroundings of metro and train stations, mainly at the east of the city with expansion to the west. Although Toxicology services are geographically related to the zones with higher density of finding of scorpions, the accessibility to the centers with antivenom may hinder its application in the recommended time; some measures to avoid possible delays in the application of the treatment are suggested
