Pemetaan Keong Fokus Oncomelania hupensis lindoensis di Empat Desa Schistosomiasis di Kabupaten Sigi dan Poso

Abstract The habitat of Oncomelania hupensis lindoensis snails was found widely spread in the three areas of the Napu, Bada and Lindu Highlands with the infection rate above 1%. The last focus distribution map of this snail was done eight years ago. Therefore, it needs to be updated. This study aimed to identify and map the primary and secondary foci area of O.hupensis lindoensis snail. Mapping of the intermediate host of schistosoma, O. hupensis lindoensis was conducted for seven month in four schistosomiasis endemic villages in Poso and Sigi District of Central Sulawesi in 2016. The result showed that snail of O. hupensis lindoensis in Sedoa was found reduced to 33 foci, in Watutau Village was also reduced to two foci, in Tomehipi Village was found increased become eight foci, and in Tomado Village was found reduced become 15 foci. The foci areas needs to be changed into agricultural land, to reduce the number and area of O. hupensis lindoensis. Abstrak Penyebaran habitat keong O. hupensis lindoensis ditemukan di tiga wilayah yaitu Dataran Tinggi Napu, Bada dan Lindu dengan infection rate di atas 1%. Data distribusi fokus telah dilakukan delapan tahun lalu melalui pemetaan fokus, sehingga perlu diperbaharui. Telah dilakukan pemetaan habitat perantara schistosomiasis keong O. hupensis lindoensis selama tujuh bulan di empat daerah endemis di Kabupaten Poso dan Sigi Sulawesi Tengah. Studi ini bertujuan memetakan dan mengidentifikasi fokus keong O. hupensis lindoensis di dataran tinggi Napu, Bada, dan Lindu, sebagai pembaharuan data perkembangan fokus di daerah endemis. Hasil pemetaan habitat hospes perantara schistosomiasis keong O. hupensis lindoensis menunjukan bahwa jumlah fokus keong O. hupensis lindoensis di Desa Sedoa menurun menjadi 33 fokus, di Desa Watutau jumlah fokus menurun menjadi dua fokus, di Desa Tomehipi meningkat menjadi delapan fokus, dan di Desa Tomado menurun menjadi 15 fokus. Aktivitas pengelolaan area fokus menjadi lahan produktif perlu diintensifkan guna mengurangi jumlah fokus O. hupensis lindoensis.
