Remote sensing (RS) permits evaluation of spatial and temporal variables that can be used for vector-borne disease models. A Landsat Thematic Mapper scene covering Canindé, Ceará in northeastern Brazil (September 25, 1986) was spectrally enhanced classified using ERDAS (Atlanta, GA) Imagine 873 4-km2 areas. The population number cases American visceral leishmaniasis (AVL) were determined each area. Relative risk (RR) ratios calculated climate, demographic, case data recorded 17 years by the Municipality Conidé. RR AVL a child less than 10 old from foothills relative to non-foothill residency 4.0 (95% confidence limit = 3.5, 4.5). children 9.1 during time when three-year rolling rain average (current year plus two previous year's precipitation) between 40 60 cm greater 100 cm. results suggest features detected RS techniques combined with climatic determine Brazil.
