Self-affinity and self-organized criticality applied to the relationship between the economic arrangements and the dengue fever spread in Bahia

Abstract

In this paper, we evaluate whether the diffusion of the dengue fever can be explained by differences among regional economies. We evaluate the dengue fever self-affinity behavior and self-organized critical behavior within the fifteen economic regions of State of Bahia, Brazil, between 2000 and 2009. The results showed two distinct behaviors for long-range correlation scaling: persistent for a month and subdiffusive for one year, according to DFA method. Furthermore, the dengue fever distribution presented power law behaviors for these data sets, according to SOC analysis. In this study, we concluded that this disease was not influenced by economic aspects or regional arrangement, and also suggest that the disease’s vector (Aedes aegypti mosquito) has adapted to all the economic regions.
