RESUMO

Dengue is the arbovirose with higher occurrence in the South Amaerica, Central America, Asian Southwest and Occidental Pacific urban centers. In the American continent the Aedes aegypti mosquito is responsible by the transmission of the dengue virus. Introduced in 1996 the disease became one of the major urban health problems in the City of Belo Horizonte, Minas Gerais State, Brazil. In 2000, the City Health Department and the Federal University of Minas Gerais developed a seroepidemiologic inquiry (Dengue Seroprevalence Inquiry in Belo Horizonte City ISDBH) to quantify the seroposivity by the dengue virus in the Sanitary Distritcts Centro-Sul, Leste e Venda Nova. This dissertation, constituted by two articles, reprocess the data obtained through the ISDBH under a analytic approach. The first dissertation Factors Associated to Infection by Dengue in the Municipality of Belo Horizonte, Minas Gerais State, Brazil: Individual Characteristics and Intraurban Differences - discuss the analysis of the infection in the Sanitary Districts, for a random sample of 627 individuals. The total infection prevalence reached 23.3%. Among the participants, 17.9% were seropositive for DENV-1 and DENV-2, 4.6% only for DENV-1 and 0.8% only for DENV-2. Seropositive individuals, when compared to seronegative persons, were more likely to reside in Sanitary Districts Leste and Venda Nova, had never moved out of their houses or neighborhoods and lived in horizontal residential buildings. Low income was associated with high prevalence rates, horizontal residential buildings with vector infestation and the lack of spatial mobility of participants with high infection rates. The seconf article - Investigations on the Sampling of a Dengue s Seroepidemiologic Study: The Population Participation - analyzes the appliance of the interviewed, considering the sociodemographic characteristics and the spatial distribution of the participants and non-participants. From the universe of 1.010 visited, 358 (35,5%) individuals didnt applied to the research, the motives for the denial were divided in four groups: house closed, denial, impossible scheduling and other motives. The descriptive analysis of the participants and non-participants profiles followed the collected variables: gender, age, region and the motive ofthe non-appliance. The Ripleys K Function test was used to the spatial observation of the events. The losses by Sanitary District were 53,3% in the Sanitary District Centro-Sul, 36,5% in the Sanitary District Leste and 27,2% in the Sanitary District Venda Nova were antecipatelly recomposed utilizing the sample plan for epidemiologic study method. The analysis showed the homogeny spatial distribution between participants and non-participants, the relevancy of the re-composition of the losses, the higher frequency in the motivated denial. The investigation of the samples spatial distribution found the bases the discutions about the ambiental and spatial ocupation of the urban space in different regions of the City of Belo Horizonte and the proper information for distinct interventions regarding vector control.
