  1. aFisher’s exact test of association
  2. bNodular lesions were found in L. tropica patients from Al Madinah (Al Jadidah) and Asir (Etoed)
  3. cUlcerated nodular lesions were found in two thirds of CL patients. Lesions were mainly localized on the face, nose and/or ear
  4. dThe criteria used by the Saudi MoH for categorizing the location of the lesions is related to the use of traditional outfits, which determines the area of the body exposed to sand fly bites
