Abstract
Ações preventivas ainda são essenciais ao controle da epidemia de AIDS; contudo, programas de prevenção eficazes dependem da distribuição correta e eficiente dos recursos de saúde. Assim, informações acerca de onde, quando, com que intensidade e como se difundirá a epidemia são valiosos. Este estudo visou obter melhor compreensão do processo de difusão espacial dos casos de AIDS em quatro Estados brasileiros. Tais padrões foram avaliados qualitativamente - estudo de mapas seqüenciais - e quantitativamente - análise de correlogramas espaciais - ao longo de dez anos, agrupados em três períodos: 1987-1989, 1990-1992 e 1993-1996. O processo de difusão foi estudado para o total de casos de AIDS e para os do sexo feminino e masculino. De modo geral, houve difusão significativa dos casos de AIDS nos períodos, mas o processo exibiu características específicas a cada Estado. As informações obtidas - em especial, os resultados da análise de correlogramas - permitem entender melhor os padrões de difusão espacial da epidemia em diferentes partes do País e podem ser empregadas para fixar parâmetros a outros modelos epidemiológicos da AIDS.
Despite new improvements in AIDS treatment, preventive measures are still essential to control the epidemic. Effective programs almost always depend on correct and efficient allocation of scarce health resources. Detailed information on the epidemic, such as where, when, and how the epidemic will spread are of great value. This study was conducted to obtain a better understanding of the dissemination of AIDS cases in four important Brazilian States. Spatial diffusion patterns were evaluated qualitatively by studying sequential maps and quantitatively by analyzing spatial correlograms. Ten years were analyzed, grouped in three periods (1987-1989, 1990-1992, and 1993-1996). The diffusion process was studied for both total AIDS cases and male and female cases. Diffusion of AIDS cases presented specific characteristics for each of the four States. Information derived from the study, especially the results of the correlogram analysis, improve our understanding of the epidemic's spatial diffusion in different parts of the country and can also be used to determine parameters for other AIDS epidemiological models.
