Abstract
- Seventeen (17) parasitologically confirmed cases of infantile kala azar (KA) are reported from 1982 to 1991 in Tunisia, in areas (Gouvernorates of Sidi Bouzid, Kasserine, Sfax, Gafsa and Tozeur) where the disease has never (or exceptionally) been reported before. This tendency to the extension of the KA areas from Northern Tunisia to the Central and Southern parts could be explained by the ecological modifications that occurred in these zones following agriculture development programs that included an important increase of water resources (wells, dams etc...). These modifications probably contributed to the enhancement of the Leishmania infantum vector population densities making it possible for transmission cycles to be implemented and maintained in these areas; the parasite could have been brought with dogs from the North of the country.
