Schistosomiasis mansoni in the northeast region of brazil: temporal modeling of positivity, hospitalization,and mortality rates.

Abstract

We aimed to analyze trends in Schistosomiasis positivity, mortality, and hospitalization rates in Northeast Brazil. 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. 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. Schistosomiasis mansoni represents an important public health problem in Pernambuco, Alagoas, Sergipe, and Bahia.
