Schistosomiasis is only found in three areas of Indonesia, namely, Napu, Lindu, and Bada highlands. Napu and Bada highlands are located in Poso District whereas Lindu highland is located in Sigi District. The presence of snails is as an indicator for determining the focus areas of intermediate host of the worm. The purpose of this study was to determine the distribution of snail focus areas of schistosomiasis in 2017 by conducting habitats and snail survey. The result showed that there were 242 foci areas of O.hupensis lindoensis in 21 villages covering a total of 1,407,225 m2 marshland area. This indicates that there is a slight reduction in the number of focus in 2017 compared to the previous year. In order to eliminate schistosomiasis in the endemic areas, a multi sectoral collaborations to modify the environment is very essential. Elimination can only be succesful if the snails and their intermediate host can be eliminated by environmental management, as to converse the snail habitats into more productive agricultural area. These data can be used as updated baseline data to eliminate the snail intermediate host. Moreover, the community involvement is needed to ensure the sustainability of the schistosomiasis control program.
