Entomological investigation following the resurgence of human visceral leishmaniasis in southern Algeria.

Visceral and cutaneous leishmaniasis are the main endemic vector born diseases in Algeria. In the Hoggar region (extreme south of the country) human visceral leishmaniasis (HVL) is known to be sporadic but during the last decade the number of cases has increased significantly. In 2010, a peak of HVL cases was registered mostly among children. Therefore an entomological survey and a retrospective study on HVL cases were carried out in order to explore the transmission of the disease. Among the sand fly caught Phlebotomus bergeroti was the most frequent species (68%) followed by Sergentomyia schwetzi (22%). In this work we describe the presence of Phlebotomus (Paraphlebotomus) kazeruni for the first time in the Hoggar region.
