Abstract INTRODUCTION We aimed to analyze trends in Schistosomiasis positivity, mortality, and hospitalization rates in Northeast Brazil. METHODS We conducted an ecological study using data from the Brazilian Schistosomiasis Control Program, and Hospital and Mortality Information Systems. A joinpoint regression model was used for temporal analysis. RESULTS The positivity(−4.7%;p<0.001) and hospitalization(−17.7%;p<0.001) rates declined globally, while the mortality remained stationary (−0.8%;p>0.05). However, the hospitalization in Alagoas(27.1%;p<0.001) and Pernambuco (35.1%;p<0.001), and the mortality in Bahia(2.9%;p<0.001) and Sergipe(4.1%;p<0.001), increased. CONCLUSIONS Schistosomiasis mansoni represents an important public health problem in Pernambuco, Alagoas, Sergipe, and Bahia.
