Abstract
Fifty unselected subjects living in Alpes-Maritimes, France, a high risk area for visceral leishmaniasis due to Leishmania infantum, were examined simultaneously by the leishmanin skin test and the Western blot technique in 1993; 32% and 38%, respectively, gave a positive reaction. The concordance of the 2 methods was 82%. Thus, in this high risk area, a large proportion of inhabitants had been exposed to the parasite. The use of these 2 tests should permit the detection of potential cases of reactivated leishmaniasis in prospective follow-up investigations.
