Analysis of the spatial distribution of dengue cases in the city of Rio de Janeiro, 2011 and 2012

Abstract: OBJECTIVE Analyze the spatial distribution of classical dengue and severe dengue cases in the city of Rio de Janeiro.METHODS Exploratory study, considering cases of classical dengue and severe dengue with laboratory confirmation of the infection in the city of Rio de Janeiro during the years 2011/2012. The georeferencing technique was applied for the cases notified in the Notification Increase Information System in the period of 2011 and 2012. For this process, the fields “street” and “number” were used. The A… Show more

“…Regarding the socioeconomic context, a survey conducted in Rio de Janeiro observed that the locations of highest occurrence of classical dengue fever and haemorrhagic fever were not coincident, the latter being more prevalent in poor neighbourhoods and slums, providing clear evidence that social vulnerability may be a major factor influencing the occurrence of aggravation [16]. The present results corroborate these observations, demonstrating that the infestation and autocorrelation indices are most evident in contiguous neighbourhoods and the poorest ones.…”

“…It comprises the quantitative study of phenomena that are geographically located in space and may be performed by visualization, exploratory analysis or spatial data modelling methods. This type of approach has been widely used in epidemiological studies and allows for an exploration of the relationship between demographic, environmental and socioeconomic information in order to detect the conditions and determinants of the arboviruses without dissociating them from the context of their territorial spaces [16].…”

“…Nonetheless, locations with social and economic vulnerability more likely have poorer sanitary conditions and less efficient vector-control interventions, which would facilitate mosquito proliferation. In Rio de Janeiro city, areas in or near favelas were detected as hot spots for dengue [39]. Consistent with our findings, a study conducted in French Guiana indicated that, early in the epidemic, the poorest neighbourhoods would have a greater risk for CHIKV infection [41].…”

“…As dengue has been endemic in Rio de Janeiro for the last three decades and Janeiro has already been identified as a hot spot for dengue and as a key region for dengue diffusion. Previous studies also identified Catumbi, a neighbourhood in the Downtown area, as a high-risk location for dengue [38,39]. In our findings, Catumbi comprised the most likely chikungunya cluster, the second most likely cluster for dengue and the third most likely for Zika.…”

“…This unit provides services to 31,000 residents of the Manguinhos District, where most houses have a single room, sanitary issues are still unsolved, monthly family income is usually lower than a the minimum wage, and more than 50% of residents have no more than an elementary school education [13]. Initiatives aimed at decreasing violence have been impeded by the activities of local drug traffickers [14].…”
