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

epidemiological surveillance data suggest a decrease in the morbidity
