title: [Epidemiological characteristics and geographical distribution of schistosomiasis and geohelminths, in the State of Sergipe, according to data from the Schistosomiasis Control Program in Sergipe].
abstract: BACKGROUND
  Schistosomiasis is endemic in Brazil, with high prevalence in the State of Sergipe, despite the existence of the Schistosomiasis Control Program (PCE).
  
  
  METHODS
  The data from Sergipe's PCE between 2005 and 2008 were surveyed. From the raw information, a database was created on a spreadsheet using the Access software. The frequency and geographic distribution of infections due to Schistosoma mansoni and other intestinal parasites were analyzed. These data were exported to the Spring 5.0.5 software for georeferencing and preparation of thematic maps of the spatial and temporal distribution according to year of evaluation.
  
  
  RESULTS
  In 2005, 13.6% (14,471/106,287) of the tests were positive for S. mansoni, 11.2% (16,196/145,069) in 2006, 11.8% (10,220/86,824) in 2007 and 10.6% (8,329/78,859) in 2008. Analysis on the maps showed that there was high prevalence of the disease in Sergipe, and particularly in the municipalities of Ilha das Flores, Santa Rosa de Lima, Santa Luzia do Itanhi and São Cristóvão. Furthermore, we evaluated the association between the frequencies of these parasitic diseases and social and developmental indicators in the different municipalities, according to data from the Brazilian Institute for Geography and Statistics (IBGE) and the Department of Water Resources (SRH). We found that municipalities with schistosomiasis prevalence higher than 15% had lower coverage of sewage systems (hygiene index) (p = 0.05). Additionally, municipalities with hookworm prevalence higher than 10% had lower educational HDI (p = 0.04).
  
  
  CONCLUSIONS
  The importance of greater control over environmental risk and educational factors needs to be emphasized in attempts to reduce the prevalence of these parasitic diseases.
