DUQUE L., Jonny E.; DA SILVA, Ricardo V.; KUWABARA, Eduardo F.  and  NAVARRO- SILVA, Mario A.. Dengue in the Paraná state, Brazil: temporal and spatial distribution in period 1995-2007. Rev. Univ. Ind. Santander. Salud [online]. 2010, vol.42, n.2, pp.113-122. ISSN 0121-0807.

Objectives: To analyze the spatial and temporal distribution of dengue in the Paraná state and its relationship to the rising of number of cases in the border areas from 1995 to 2007. Methods: Data of occurrence of autochthonous and allochthonous dengue cases in Paraná were georeferenced whit ArcView GIS 3.2. It was also performed an analysis of the Pearson correlation (r) between the total number cases to State of Paraná with Mato Grosso and São Paulo states, Brazil, Argentina and Paraguay. Results: The maps' analysis allowed the recognition of areas with higher dengue incidence and the direction of dispersion within the State. It is outstanding the occurrence of three epidemical waves with peaks in 1995/96, 2002/03 and 2006/07. It highlights the metropolitan regions of Londrina and Maringá and the city of Foz do Iguaçu, as large urban centers, present a high number of dengue cases. The area that comprises the West, Mid-west, Northwest, Mid-north and the so-called "Pioneer North" mesoregions contributed with 98.47% of the total number of cases and with 99.98% of solely the autochthonous ones. Conclusions: The occurrence of epidemic waves and the notification of continuous cases of dengue, with serologic confirmation, it is an indication that this disease has become endemic in the state. It is observed that the largest number of cases in the Parana state occurs in the border areas with Paraguay and currency with the Mato Grosso do Sul state. Salud UIS 2010; 42: 113-122.
