The aim of this study was to analyze the magnitude and trend of American Tegumentary Leishmaniasis (ATL) in the State of São Paulo from 1975 to 2008. An ecological study that classified municipalities according to the magnitude of transmission was performed. From 1975 to 1985, 1,281 cases of ATL were registered in 45 municipalities, rising to 258 municipalities and 4,093 cases from 1986 to 1995; and reaching 385 municipalities and 7,604 cases from 1996 to 2008.

In the municipality of Dracena, in the state of São Paulo, we analysed 5,889 Lutzomyia longipalpis specimens collected from the peridomiciles of 14 houses in a sector where American visceral leishmaniasis (AVL) is transmitted to humans and dogs. The goal was to analyse the dispersion and a theoretical fitting of the species occurrence probability.

Methods: The 9 areas were grouped into 4 strata according to soil use and occupation. Larvae and pupas were collected in a sample of approximately 500 buildings in each area.
Article Synopsis
- The study analyzes serological data on Chagas' disease from the late 1960s to 1999, focusing on two key periods: the initial data collection from 1960-1983 and a later description of the disease from 1984-1999.
- The serological surveillance involved schoolchildren and the general population from specific municipalities in São Paulo, showing low seropositivity rates and patterns indicating low endemicity in some areas, with potential oral transmission sources.
- The conclusions emphasize the need for collaborative efforts among scientific institutions to study and characterize different strains of Trypanosoma, which could enhance understanding of Chagas' disease epidemiology and improve public health initiatives.
