Entomological and epidemiological study of a new focus of cutaneous leishmaniasis in Morocco.
Cutaneous leishmaniasis (CL) due to Leishmania tropica Wright has become an increasingly important problem in Al-Haouz province, Morocco. The objective of this paper was to undertake a retrospective analysis of CL between 2000 and 2006 and to study the sandfly fauna for the first time in this focus. The consultation of bulletins, registers and monthly and annual reports published by local and national medical services permitted a global synthesis of CL in Al-Haouz between 2000 and 2006. Sandflies were collected using sticky-paper traps in five selected stations in two communes, Ourika and Sti Fadma, the most affected by CL in Al-Haouz. Overall, 2,648 sandflies, belonging to five species of Phlebotomus and three of Sergentomyia, were collected. Phlebotomus sergenti Parrot (14.5%) was found in all studied stations where it was associated with domestic and peridomestic habitats. Based on this first report on ecology of sandflies and epidemiology of CL, Al-Haouz seems to be a typical focus of L. tropica and P. sergenti like the other Moroccan foci. Two communes, Sti Fadma and Ourika, constituted an important CL micro-focus in this region. Considering their economical importance (trade and tourism), they contribute probably to the dissemination of Leishmania parasite in bordering regions.
