Aspectos epidemiológicos da leishmaniose tegumentar em área endêmica do Estado do Paraná, Brasil

[摘要] An epidemiological investigation of cutaneous leishmaniasis (CL) was performed in 1992 and 1993 in an endemic area of Jussara and Terra Boa counties, in the Northern Paraná State. The study covered 684 individuals from a population of approximately 1,400 from six agricultural areas (Fazenda Palmital, Cerâmica Andirá, Fazenda Jussara, Fazenda Lagoa, Destilaria Melhoramentos, and Fazenda Mururê) in Northern Paraná, Brazil. The mean frequency of CL history was 19.9%. The highest frequency was at Fazenda Jussara (40.5%). Based on the indirect immunofluorescence test, 58 (8.5%) presented significant titers of anti-Leishmania antibody, 17 (29.3%) of whom had no history of CL. The Montenegro skin test was applied to 97 individuals with a history of CL and was positive in 80 (82.5%). During the survey, seven individuals presented lesions, four of which were positive for Leishmania sp.. The strain isolated was identified as Leishmania (Viannia) braziliensis.
