Social geography of AIDS in Brazil: identifying patterns of regional inequalities.

The trend towards decline and stabilization of the AIDS epidemic in Brazil should be analyzed carefully, since aggregate data can mask regional or local inequalities in such a large and diverse country. The current study reevaluates the epidemic's spatial dissemination and the AIDS-related mortality pattern in Brazil. The study considered all AIDS cases diagnosed in individuals over 18 years of age and living in Brazil, as well as AIDS deaths recorded in 1998-2008.

Spatial modeling of dengue and socio-environmental indicators in the city of Rio de Janeiro, Brazil.

This study analyzed the spatial distribution of dengue in Rio de Janeiro, Brazil, in 2006, and associations between the incidence per 100,000 inhabitants and socio-environmental variables. The study analyzed reported dengue cases among the city's inhabitants, rainfall, Breteau index (for Aedes aegypti and Aedes albopictus), Gini index, and social development index. We conducted mapping and used the global Moran index to measure the indicators' spatial autocorrelation, which was positive for all variables.

[Socio-demographic factors and the dengue fever epidemic in 2002 in the State of Rio de Janeiro, Brazil].

This study analyzed the dengue fever epidemic in 2002 and the socio-demographic context of the State of Rio de Janeiro, Brazil, using spatial analysis and statistical modeling. The incidence rate was calculated for resident dengue cases in the State in 2002. The study analyzed associations between incidence and socio-demographic variables and spatial autocorrelation using the Moran Global Index, which showed spatial dependence for both the outcome and the independent variables.
