Abstract

ARAUJO, José Raimundo de; FERREIRA, Efigênia Ferreira e  and  ABREU, Mauro Henrique Nogueira Guimarães de. Systematic review of spatial analysis studies on dengue in Brazil. Rev. bras. epidemiol. [online]. 2008, vol.11, n.4, pp. 696-708. ISSN 1415-790X.  http://dx.doi.org/10.1590/S1415-790X2008000400016.

The present study aimed to carry out a systematic review of geoprocessing studies on the dengue vector and the disease in Brazil. The search was conducted in the Pubmed and Bireme databases and in Scielo virtual library. The selection was carried out using inclusion criteria, such as: original articles on dengue and the use of geoprocessing techniques, published in English or in Portuguese, from 1998 to 2007; final course works; and studies presented at congresses. Studies which evaluated the disease in other countries were excluded. The key words used were "spatial distribution and dengue", "dengue and geoprocessing", "spatial analysis and dengue", "geographic information system and dengue" and their translations into Portuguese. In the Scielo database search, 15 articles were found, from which 8 were selected; in Pubmed, 11 articles were identified and 3 were selected; and in Bireme 20 articles were found, from which 2 were selected. The present review allowed the analysis of 7 studies on the spatial pattern of dengue cases, 5 studies on dengue vectors and one study that evaluated dengue cases and vectors, simultaneously. The non-utilization of geoprocessing techniques was frequent. Social aspects were frequently associated with the spatial distribution of dengue. The study concludes that spatial analyses of dengue in Brazil, especially those that evaluated vectors, used geoprocessing tools poorly. Socioeconomic aspects are important to understand the spatial distribution of dengue.
