Auteurs

Seeking to understand how humans, by the settlements they create (among other means), influence the operation of the pathogen system of sleeping sickness, the authors performed a diachronic analysis of the landscape and settlement dynamics by comparing topographic maps from 1957, a satellite image from 2004, and georeferenced censuses from 2009 and 2001. It appears that the extreme mobility of the population between the continent and the islands is the principal cause for the continuation of this disease at the mouth of the Rio Pongo.
