The program of schistosomiasis control for the State of São
Paulo, where only low endemicity areas occur, is discussed in this paper.
Inclusion of schistosomiasis among the diseases due to obligatory
notification is considered as a measure of great importance. Accordingly
the search for passive cases conducted by the publich health system
acquired major importance in the disease surveillance. As from 1981 to
1992 only 11% of the detected cases were considered as autochthonous.
The main transmission areas are located at the Litoral and Paraiba
Valley regions.
In the period of time under analysis, the epidemiological
surveillance data suggest a decrease in the morbidity and in the
autochthony tendency in the State of São Paulo.
