Oncomelania hupensis lindoensis as an intermediate host grows widely in rice field, cacao field and also neglected rice field.Schistosomiasis in those endemic areas was fluctuated every years. Prevalence of schistosomiasis in Napu were 0.64% in 2005, 1.21 %in 2006, and 1.14% in 2007. Prevalence in Lindu were 0.66% in 2005, 0.52 % in 2006, and 1.4% in 2007. The aim of this study was to investigate schistosomiasis case from 1984-2007. It is expected that it can determine the correlation between number of focus area and schistosomiasis. From this study, it showed that the fluctuation of prevalence was related to the numbers of focus area, with p-value was 0.025. In Central Sulawesi Schistosomiasis is difficult to be eliminated because there were many problems.   Keywords: correlation, focus area, schistosomiasis, Oncomelania hupensis lindoensis.
