[Epidemiology of leishmaniasis in Algeria. 3. Systematic screening of cutaneous leishmaniasis in the Biskra area].

In the Biskra area which is a historical focus of cutaneous leishmaniasis, the authors have carried out a systematic survey of the disease among the school age population (age interval: 6-15 years of age). The incidence of the disease found through the detection of suspect cutaneous leishmaniasis scars rose to 32.4%. The incidence brought about by intradermal skin-testing (to Leishmanin) was 76.9%. The comparative value of the two systematic survey methods is discussed with reference to the situation of other endemic foci.
