This study aims to determine spatial patterns of mortality and morbidity for five health prob-lems in an urban environment: homicides, ado-lescent pregnancy, asthma hospitalization, and two vector-borne diseases, dengue and visceral leishmaniasis. All events were obtained through the city health database and geoprocessed using residential addresses and 80 planning units consisting of census tracts. We used thematic maps, proportionate mortality/morbidity ratios by planning unit, and the overlapped rank of the 20th worse planning unit rates for each event. A spatial pattern of high rates of homi-cides, proportion of young mothers, and hospi-talization due to asthma overlapped in socially and economically disadvantaged areas. For the two vector-borne diseases, high rates with great dispersion were found in underprivileged areas, in contrast with very low rates among higher in-come areas.
The results indicated the coexis-tence of heavier disease burden for residents of urban areas where poverty and lack of effective public health policies may be modulating social health problems. For the two vector-borne dis-eases, an environmental intervention in one mosquito-borne disease might be playing a role in the other’s incidence.
