Fiocruz | Geographical distribution of American cutaneous leishmaniasis and its phlebotomine vectors (Diptera: Psychodidae) in the state of São Paulo, Brazil

To understand both the vector and disease distribution we used an initial step in applying geographic information systems (GIS) and remote sensing (RS) tools to map disease-risk. A dataset containing 910 individual records of sand fly occurrence in the state of São Paulo, from 37 different sources, was compiled.

These records date from between 1943 to 2009, and describe the presence of at least one of the six incriminated or suspected sand fly vector species in 183/645 (28.4%) municipalities. For the remaining 462 (71.6%) municipalities, we were unable to locate records of any of the six incriminated or suspected sand fly vector species (Nyssomyia intermedia, N. neivai, N. whitmani, Pintomyia fischeri, P. pessoai and Migonemyia migonei).
