Objective:

to characterize confirmed human leptospirosis cases resident in Porto Alegre, Rio Grande do Sul, Brazil, between 2007 and 2013, and their spatial distribution.

Methods:

this was a descriptive study of cases registered on the Notifiable Diseases Information System; we investigated neighborhoods and areas in the catchment area of Health Units (US) with highest case occurrence, using spatial analysis as per the Kernel technique.

Results:

228 cases were confirmed in the period, with cumulative incidence of 2.3 cases/100,000 inhabitants; the majority were adult males (81.6%), economically active (82.5%) and had low schooling (45.8%); the main occupations were recyclable waste collector (15.8%) and builder/builder’s mate (15.2%); six priority US were identified for leptospirosis control and prevention actions.

Conclusion:

the epidemiological profile and spatial distribution of cases suggest that there continue to be environmental risk factors favoring human leptospirosis occurrence in these areas.
