Epidemiological characteristics of a new focus of cutaneous leishmaniasis caused by Leishmania tropica in Settat, Morocco (original) (raw)

Highlights ►We conducted the first epidemiological and molecular study in the new cutanuous leishmaniasis focus of Settat province in Morocco ►553 cases were reported between 2007 and 2012. Most of cases were from El Borouj sector. ►The high prevalence of lesion was recorded among children under 11 years old ► The lesions were typically small and dry ► L. tropica MON-102 were identified by PCR ITS1 and isoenzyme technique on starch gel electrophoresis ABSTRACT Anew emerging focus of human cutaneous leishmaniasis (HCL) caused by Leishmaniatropica was identified within the province of Settat. This study was performed in order to analyse the reasons of the extension of CL in this area, and to describe the clinico-epidemiological characteristic of this emerging focus during 2007-2012. A total of 553 suspected cases of CL were diagnosed in laboratory of Settat, controlled and confirmed in reference national laboratory of leishmaniasis in Rabat.

The lesions were typically small, dry and mostly located on the face and extremities. Majority of infection (25 %) was recorded among children under 11 years old, and female (72%).
