The study investigated the spread of dengue in the Brazilian dry climate region of Bahia from 2000 to 2009 through a multiscale statistical analysis. Results showed significant and persistent cross-correlation between most economic regions, suggesting that economic regions or climatic conditions are not statistically significant in the spread of dengue in Bahia. The study's main contribution lies in revealing multiple aspects related to the propagation of dengue in dry climate regions through cross-correlation analysis.
We investigated the relation between the spread, time scale, and spatial arrangement of dengue in Bahia, a Brazilian dry climate region, for the period 2000 to 2009. The degree of cross-correlation is calculated for 15 economic regions. We propose a multiscale statistical analysis to datasets of dengue cases in order to verify the effect of infection dispersal on the economic regions from the metropolitan region of Salvador. Our empirical results support a significant and persistent cross-correlation between most regions, reinforcing the idea that economic regions or climatic conditions are non-statistically significant in the spread of dengue in the State of Bahia. Our main contribution lies in the cross-correlation results revealing multiple aspects related to the propagation of dengue in dry climate regions.
