“…Some studies have shown that when transmission of dengue begins to occur in a certain urban space, there is a directly proportional association between the levels of infestation and incidence with the living conditions observed in different neighborhoods or homogeneous areas [12][13][14][15] . With the progression of the endemic setting and the repetition of epidemic cycles this initial pattern tends to change and ceases to show association.…”

“…In this way, given that vector control depends essentially on the level of involvement of the population in daily actions to eliminate breeding pools, populations with a better level of schooling and income would be expected to live in neighborhoods with lower or null building infestation rates. However, other factors may change this expectation, as, for example, a higher number of containers with breeding potential, such as not regularly treated swimming pools, large badly sealed water reservoirs, vases, types of plants used in gardening and ornaments, fountains, and others [15][16][17] .…”

Introduction: Cuiaba presents a huge number of cases of dengue in the endemic periods as well as in the cyclical epidemics. The aim of the study was to analyze the intra-urban differentials of the incidence in 2007 and 2008 relating them with socio--economical and environmental life conditions. Method: study of ecological approach using secondary data. The characterization of the life conditions was gotten from the Demographic Census (IBGE, 2000) and the epidemiologic data from the Surveillance National System (SINAN). The socio-economical index was based on school level and income of the head of family and overcrowding; the socioambiental index used information about sanitation and proportion of precarious domiciles. The variables were classified in quintis and points were attributed for each one. The score for neighborhood was resultant of the addition of the points for each variable. The neighborhoods had been classified in stratus of risk from the combination of results of the two indexes. Results: The incidence was lesser in stratus of average and low risk and very high in the stratum of the highest risk but was bigger then expected in the stratum classified at minimum risk indicating dissociation between life conditions and occurrence of the illness. Conclusion: Higher incidences of the dengue fever in Cuiaba in 2007 and 2008 have been observed in places with precarious conditions of sanitation and inhabited by populations with lesser level of income and education level but there is no linear correlation between life conditions and incidence.

ABSTRACT:This paper aims to describe a set of epidemiological information regarding the spatial distribution of selected neglected diseases in Brazil from 2007 to 2009 and their correlation with health care infrastructure and socio-economic indicators. We performed an ecological study of the spatial analysis, based on the incidence of tuberculosis, visceral leishmaniasis, American cutaneous leishmaniasis, malaria and prevalence of leprosy and schistosomiasis. Maps with the spatial distribution of the prevalence and incidence rates were drawn, as well as cluster detection maps, applying spatial statistical analysis techniques. A thematic map with the total distribution of priority municipalities was developed for each disease. Malaria and schistosomiasis had the highest incidence and prevalence rates respectively. All diseases analyzed showed dependence in the spatial correlation measure. A total of 1,630 Brazilians municipalities (29%) were considered by the Ministry of Health as a priority to receive control actions for at least one of the studied diseases.

25Background 26 Around 14% of world dengue virus (DENV) cases occur in the Americas, the majority 27 of them in Brazil. Although socioeconomic, environmental and behavioral correlates 28 of dengue have been analyzed for different contexts, the role played by population 29 mobility on DENV epidemics, especially at the local level, remains scant. This study 30 assesses whether the daily pattern of population mobility is associated with DENV 31 transmission in Campinas, a Brazilian major city with over 1.2 million inhabitants in 32 São Paulo state. 33 Methodology/Principal Findings 34 DENV notifications from 2007 to 2015 were geocoded at street level (n=114,884) and 35 combined with sociodemographic and environmental data from the 2010 Population 36 Census. Population mobility was extracted from the Origin-Destination Survey 37 (ODS), carried out in 2011, and daily precipitation was obtained from satellite 38 imagery. Zero-Inflated Negative Binomial (ZINB) regression models controlled by 39 demographic and environmental factors revealed that high population mobility had a 40 substantial positive effect on higher risk for DENV transmission. High income and 41 residence in apartments were found to be protective against the disease, while 42 unpaved streets, number of strategic points (such as scrapyards and tire repair 43 shops), and precipitation were consistently risk factors for DENV infection.44 Conclusions/Significance 45 The use of fine-scale geographical data can unravel transmission idiosyncrasies not 46 evident from a coarse spatial analysis. Even in a major city like Campinas, the vast 47 majority of population daily mobility occurs at short distances. Based on our results, 48 public policies on DENV transmission control should dedicate special attention to 49 local hubs of population mobility, especially during high transmission weeks and in 50 high dengue incidence areas. 51 52 Author Summary 53 Currently, about half of the world population is at risk of a dengue infection. Numerous 54 studies have addressed the socioeconomic and environmental determinants of the 55 disease. However, little is known about the role played by population mobility on 56 dengue transmission, particularly at the local scale. This study aims at investigating 57 this issue. Our hypothesis was that population movements are a prominent driving 58 force for dengue diffusion locally. We investigated the case of Campinas, a 59 municipality with over 1.2 million inhabitants in Brazil that recorded dengue epidemics 60 in 2007, 2014 and 2015. Our study focused on the years 2007 to 2015, comprising 61 more than 114 thousand cases, geocoded to the household address, and combined 62 with socioeconomic, environmental and daily population mobility data. Our results 63showed that even controlling for demographic and environmental factors, population 64 mobility was the most important predictor for dengue fever incidence. 90 is in course in the municipality [11]. Therefore, DENV remains a public health 91 challenge in Campinas. 92While soc...
