RESUMO

Introduction. The northern coast of the State of São Paulo was, up to the decade of the 1980´s, hypoendemic for the transmission of American cutaneous leishmaniasis (ACL). However, as from the decade of the 1990´s this disease acquired epidemic characteristic in all the municipalities: Caraguatatuba, Ilhabela, São Sebastião and Ubatuba. Objective. To undertake a descriptive study of the occurrences of the autochthonous cases of ACL in the four municipalities of the northern coast of the state of São Paulo, between 1993 and 2005, and to record the phlebotomine species in the area of transmission. Methods. Secondary data of spatial and temporal distribution and personal characteristics were analyzed from the records of autochthonous ACL cases notified to the epidemiological surveillance service of the State Health Secretariat. Information on phlebotomines were obtained from data of entomological captures undertaken by the Superintendência de Controle de Endemias. Results. The ACL presented heterogeneous spatial distribution with both isolated and clustered cases. There was synchronicity in the occurrence of the disease in all the municipalities, with cyclicality at intervals of from six to eight years. All age groups and both sexes were affected, without any particular profession. The phebotomine fauna consisted of sixteen species, with Ny. intermedia predominating (>80.4%) both in the peri and intra domicíle. Conclusions. ACL presented a close relation with the forest and its transmission occurs in the peri and intra-domicile, in the periurban environment and within the forest. In this latter case the transmission is more closely related to the enzootic foci.
