| Abstract | Dengue is considered the most important viral disease transmitted by mosquitoes in the world. Several factors combine to produce conditions favorable epidemiological virus transmission by the mosquito Aedes aegypti, such as the rapid growth of rural-urban migration, inadequate basic urban infrastructure (eg, store water in containers near homes) and increased volume of waste solids such as plastic containers and other discarded objects left that provide larval habitats in urban areas. This study aimed to analyze the spatial and temporal distribution of domiciliary infestation by Aedes aegypti, considering the occurrence of dengue cases and seeking to associate themselves with sociodemographic indicators in Itaborai, Rio de Janeiro. Variables were used on the characteristics of urban infrastructure (garbage, water, sewage) and education and sex, available for the 2010 Demographic Census (IBGE) for the calculation of demographic indicators. To describe the distribution of the disease for Local Surveillance Unit (LVU) cumulative incidences were calculated monthly from 2007 and 2008. Moreover, the average incidence was calculated which corresponds to the loop epidemic of greater magnitude in 2008 (Jan to Aug). To calculate the rate of infestation by SISFAD obtained was used to mar/2008 Oct/2007 period, by virtue of having been the period of highest vector density that preceded the handle epidemic of greater magnitude in 2008. To analyze the correlation matrix was constructed for Pearson correlation coefficient between the IIP and the incidence of dengue and sociodemographic indicators. Areas of greatest risk for dengue were detected by the kernel method, through the quartic kernel function. The pattern of dengue transmission shows the observed increase in vector density preceded the increase in incidence rates. Although the IIP, most UVLS, have been below 0.99 the disease remained above 40 cases per 10,000 inhabitants in the municipality. It is noteworthy that Itaborai presents a serious problem in form of water supply in almost all general UVLS. Most UVLS remained in the range 0:01 to 20:00, and the supply per well was above 40% in most of the city. The IIP was positively correlated with the rate of dengue Bayesian (r = 0.641 / p = 0.010), indicating that when there is an increase in rates can be also increased rates. Although the indices in the region have not exceeded the recommendations by the ministry of health (1%), the period analyzed in this study (Jan to Aug/2008) coincides with the reintroduction of the virus type 2 in the State of Rio de Janeiro, which probably confirmed to the increase in incidence rates in the region. In the analysis of Kernel estimation was possible to identify the regions of greatest risk for dengue in Itaborai were also those closer to the main highways. The results of this study indicate which should be directed to the improvement of control and surveillance and the structural improvements that interfere with living conditions and health of the Itaborai |
