| Outline of Final Research Achievements |
In the Visayas region of the Philippines, a large-scale disaster occurred at the end of 2013 due to hit by huge typhoon Yolanda. The purpose of this research is to grasp the recovery situation of water environment and to evaluate the impact on the vector snail of schistosomiasis japonica which is an endemic disease in the affected area in Leyte Island. Through this pilot study in collaboration with counterpart researchers at DOH's two regional core hospitals of East Visayas Regional Medical Center and Schistosomiasis Research and Control Hospital, Leyte Island, it was strongly suggested that some drinking water sources in the affected areas was very contaminated with nitrate and E. coli just after hit of the typhoon. Also, there are still many vector snail Oncomelania quadrasi was collected in the endemic areas of the island, and the continuous future analysis of some specific vegetation suggested that the Japanese GIS vector surveillance system might be adoptable.

本研究成果の意義は、フィリピンレイテ島内の保健省の２中核病院と連携することで同施設との研究協力・支援および本研究が提案するGIS監視システムを、住血吸虫媒介貝モニタリング地区に導入する糸口を得た事である。本研究ではヨランダ台風後の媒介貝の個体数に与えた影響を十分検証できなかった。しかし、台風が飲料水源としての水環境に与えた影響を、水質分析を通じてある程度明らかにすることが出来た。また、フィリピンでの日本住血吸虫症の発見から今日に至るまでの予防対策の歴史と本研究の紹介に関わる総説を発表し、1970年代でのフィリピン政府と日本政府の共同作業による住血吸虫症対策への貢献について解説した。
