title: [Retrospective eco-epidemiology as a tool for the surveillance of leishmaniasis in Misiones, Argentina, 1920-2014].
abstract: A retrospective analytical method is presented, based on theoretical eco-epidemiology, applied on a subnational spatial scale. This method was used here to describe scenarios for the transmission of leishmaniasis in the Argentine province of Misiones- bordering Brazil and Paraguay-and formed the basis for recommendations for surveillance and control appropriate to the subnational scale. An exhaustive search of the literature on leishmaniasis in the province was carried out. Three scenarios for the transmission of cutaneous leishmaniasis (CL) and visceral leishmaniasis (VL) were found, corresponding to three periods: from 1920 to 1997, during which the transmission of CL distributed over time and space was confirmed; 1998 to 2005, during which there were focal outbreaks of CL; and 2006 to 2014, during which outbreaks were also reported and the geographical dispersion of VL was documented. To describe the risk scenarios and the anthropic processes that produce them, the results were summarized and integrated into the social, historical, and bio-ecological context of each period. Surveillance and control recommendations are based on the territory studied. They include establishing active surveillance to monitor possible rising trends in parasitic and vector circulation, conducting studies of any focal outbreak in order to confirm indigenous transmission and severity. Also, it should be a legal requirement for persons responsible for projects that alter the environment to adopt additional control measures, such as studies assessing transmission risk, risk mitigation, early detection, and timely case management.
