Resumen:
This article reviewed, from the eco-epidemiological point of view, the papers available about tegumentary leishmaniasis (TL) in Argentina since the first reported outbreak (1985-1987), including unpublished data. Three time-space scales were discriminated for analytical purposes: 1) region/decade, 2) epidemic foci/year, 3) capture station/day/month. Regional: It was observed an incremental trend of the incidence, of the peridomestic transmission, of the outbreak frequency and distribution (east-west), simultaneously with the dispersion and prevalence of Lutzomyia neivai, vector of Leishmania braziliensis,Regional: It was observed an incremental trend of the incidence, of the peridomestic transmission, of the outbreak frequency and distribution (east-west), simultaneously with the dispersion and prevalence of Lutzomyia neivai, vector of Leishmania braziliensis,Lutzomyia neivai, vector of Leishmania braziliensis, in modified environments. Epidemic foci: three transmission scenarios were defined and characterized: 1) forest cycle/forest transmission, 2) forest cycle/peridomestic transmission, 3) peridomestic cycle/rural and peri-urban peridomestic transmission. Each outbreak reported in Argentina was assigned to one out of the three scenarios. Capture station: Lu. neivai distribution probed to be microfocal, it behaves as a metapopulation that can recolonize the peridomestic environment from source populations, with bimodal annual dynamics dependant of the temperature and rainfall. The conclusions in each scale and category were discussed in the frame of potential surveillance and control strategies.Epidemic foci: three transmission scenarios were defined and characterized: 1) forest cycle/forest transmission, 2) forest cycle/peridomestic transmission, 3) peridomestic cycle/rural and peri-urban peridomestic transmission.
