          Abstract

          Este trabalho analisa as características de um dos lugares de transmissão de maior relevância da leishmaniose tegumentar na cidade do Rio de Janeiro, Brasil, considerando sua configuração territorial e as relações desta com processos de organização do espaço. Utilizou-se o modelo de análise do processo de ocupação e organização do espaço urbano, em escala local, considerando-se as novas funções adquiridas pelos elementos espaciais expressos por diferentes relações de trabalho, uso do solo e valor da terra. Empregaram-se técnicas de geoprocessamento e de classificação de imagens obtidas por sensoriamento remoto, localização de domicílios e casos de leishmaniose tegumentar, associados a dados qualitativos sobre o processo histórico de ocupação e uso do solo. A análise mostrou áreas com distintas condições de vulnerabilidade, e que mudanças destas condições viabilizaram a produção da epidemia em um determinado período e sua posterior redução. O estudo contribui para o monitoramento da enfermidade em nível local e para a aplicação de medidas eficazes para as ações de vigilância e controle da leishmaniose tegumentar.

          This study analyzes the characteristics of one of the main foci for cutaneous leishmaniasis transmission in the city of Rio de Janeiro, Brazil, examining its territorial configuration and the relations with spatial organization processes. An analytical model was applied to the process of occupation and organization of urban space on a local scale, considering the new functions acquired by the spatial elements expressed by different work relations, land use, and land value. The study employed geoprocessing techniques and classification of images obtained by remote sensing, localization of households, and cases of cutaneous leishmaniasis, associated with qualitative data on the historical process of land occupation and use. The analysis detected areas with distinct conditions of vulnerability and showed that changes in these conditions allowed production of the epidemic in a given time period and its subsequent reduction. The study contributes to monitoring of the disease at the local level and application of effective measures for cutaneous leishmaniasis surveillance and control.

          Spatial epidemiology: an emerging (or re-emerging) discipline.

          Spatial epidemiology is the study of spatial variation in disease risk or incidence. Several ecological processes can result in strong spatial patterns of such risk or incidence: for example, pathogen dispersal might be highly localized, vectors or reservoirs for pathogens might be spatially restricted, or susceptible hosts might be clumped. Here, we briefly describe approaches to spatial epidemiology that are spatially implicit, such as metapopulation models of disease transmission, and then focus on research in spatial epidemiology that is spatially explicit, such as the creation of risk maps for particular geographical areas. Although the spatial dynamics of infectious diseases are the subject of intensive study, the impacts of landscape structure on epidemiological processes have so far been neglected. The few studies that demonstrate how landscape composition (types of elements) and configuration (spatial positions of those elements) influence disease risk or incidence suggest that a true integration of landscape ecology with epidemiology will be fruitful.
