Distribution of schistosomiasis intermediate snail in Lore Lindu National Park, Central Sulawesi

Abstract

Schistosomiasis in Indonesia is only found in three locations, namely the Napu Highland and the Bada Highland in Poso District and the Lindu Highland in Sigi District, Central Sulawesi Province. The disease is caused by Schistosoma japonicum with snail Oncomelania hupensis lindoensis as its intermediate host. The previous study found that almost all of this host snail foci area were distributed in the seepage water near the Lore Lindu National Park area. Unfortunately, there was no evidence whether O. h. lindoensis exists in the Lore Lindu National Park Area. The study aimed to map the focus areas of schistosomiasis intermediate host snails in the Lore Lindu National Park. The survey was conducted in February 2018, covering 12 villages belong to Napu Highland, Bada Highland, and Lindu Highland. Data collection included surveys on the snail habitat and the snail density. In both activities, geographic coordinates were determined using Global Positioning System (GPS). The results showed 14 foci areas of O. h. lindoensis were found in the buffer zone of Lore Lindu National Park.
