Resumo: The epidemiological study was conducted during the 1973-1984 period. The clinical prospective exam and Montenegro skin, immunoflurescent and passive hemagglutination tests have been carried out in three small localities between Pedro de Toledo e Miracatu municipalities, São Paulo, Brazil. The retrospective study of human-cases involved 108 and 65 cases registered in Pedro de Toledo e Miracatu, respectively. In the three communities studied, 273 people were examinated clinically and serologically. Twenty two individuals had had signals of cutaneous leishmaniasis; 10.2 and 12.8% were seropositive to IF and HA. Leishmanin skin testing of a sample of 154 people residents in Pedra do Largo showed prevalence of Leishmania infection in 25.5%. This result involved individual of all ages and sex. However, 5.8% of them were from 0 to 9 years old. The data confirmed that active parasite transmission didn't occur every year, either. The human infection seems not to depend on man contact with a forest. The incidence relatively low suggests low endemic area for cutaneous leishmaniasis and an explosive behavior of the cases. The temporal distribution of disease was irregular and the epidemiological pattern seen was different from the other endemic area of South America

Foi feita uma análise retrospectiva de 108 e 65 casos humanos, respectivamente, para os dois municípios acima. Outro estudo prospectivo foi realizado através do exame clínico e testes de Montenegro, imunofluorescência indireta (IF) e hemaglutinação passiva (HA). Duzentos e setenta e três pessoas foram examinadas, sendo que 22 tinham leishmaniose clínica; 10,2 e 12,8% foram soropositivos à IF e HA, respectivamente. O teste de Montenegro foi aplicado em 154 indivíduos residentes em Pedra do Largo, com prevalência de 25,5% de infecção humana. Destes, 5,8% eram crianças com idade entre 0 e 9 anos. A morbidade mostrou-se variável no tempo, manifestada sob a forma de surtos epidêmicos explosivos e sugerindo feição cíclica ainda mal definida. Notou-se tendência para incidência nula em período subseqüente a cada surto. O aspecto epidemiológico geral mostra uma leishmaniose tegumentar com baixa endemicidade. O padrão de transmissão pareceu não depender do contato do homem com a floresta e a infecção humana sem distinção entre crianças e adultos Universidade de São Paulo.
