Geographical and occupational aspects of leptospirosis in the coffee-triangle region of Colombia, 2007-2011.

Background: There are few studies occupationally profiling as well as using Geographic information system (GIS) to map human leptospirosis. There are no detailed, municipality-level, epidemiological maps in Colombia neither in South America. We developed such maps for the Coffee-triangle region, Colombia and assess some occupational issues.
