Resumen
Introduction: Rio de Janeiro is the second-largest city in Brazil, with strong socio-spatial
segregation, and diverse and heterogeneous land use, occupation, and landscapes. The complexity
of dengue requires the construction of surveillance and control tools that take into account the
historical, social, economic, and environmental processes mediated in the territory as a central axis of
public policy. In this context, this study aimed to stratify the city into areas of receptivity to dengue,
using innovative “territorial indicators” because they are built based on the actual occupation of
the territory. Methods: We designed and constructed 17 indicators that sought to characterize the
transformed and inhabited space according to receptivity to dengue. We used data on land use and
occupation, connectivity, climate, and landscape. We developed the dengue receptivity through
principal component analysis (PCA), using multiple criteria analysis and map algebra integrated in a
GIS platform. Results: The most receptive areas were concentrated in the transition between the north
and west zones of the city, a region of unconsolidated urban sprawl. The areas of greatest receptivity
had the highest incidence and density of Aedes eggs during the study period. The correlation between
receptivity index and incidence rate was positive in the epidemic years. Conclusion: The proposed
set of indicators was able to identify areas of greater receptivity, such as regions of disorderly urban
sprawl, with a concentration of social and environmental processes that are related to the occurrence
of dengue outbreaks and high vector density. On the other hand, population immunity plays an
important role in the spatial distribution of dengue during non-epidemic years.
