Abstract
Study of the spatial distribution of general VL and VL-HIV coinfection in the city of Bauru - SP, Brazil between 2003 to 2016. The cases were georeferenced and attributed to the Census sectors using demographic, socioeconomic and urban infrastructure predictors. The incidence in these sectors was analyzed in univariate and multivariate one-step Poisson regression models.
Highlights
The expansion of Visceral Leishmaniasis in areas of recent emergency in the last two decades in Brazil can be understood by spatial analysis
The incidence of Visceral Leishmaniasis (VL) was negatively associated with per capita income (Incident Rate Ratio [IRR], 0.89; 95% confidence interval [CI], 0.860.92) and population density (IRR, 94; 95% CI, 0.90-0.97), while co-infection was negatively associated with per capita income (IRR, 0.80; 95% CI, 0.71-0.91) and proportion of streets with rain drainage (TIR, 0.87; 95% CI, 0.78-0.98)
We studied the spatial distribution of overall VL
Summary
The expansion of Visceral Leishmaniasis in areas of recent emergency in the last two decades in Brazil can be understood by spatial analysis. The area affected spread southwards affecting São Paulo, the most populous state in the country. In this setting, the epidemics of VL and AIDS intertwined [3]. In urban areas of recent emergence, the spatial distribution of VL cases is not homogeneous [4]. Previous studies suggest that socioeconomic and environmental factors may shape de spatial distribution VL incidence [5]. The study of those factors is likely to provide clues to determinants of the emergence of VL, pointing to areas/populations at risk and helping in directing preventive measures [6]
