Parasitological and malacological surveys were made in the Afar tribal area on the flood plains of the Awash River. S. haematobium--infections are most prevalent among seminomadic Afar living around the swamps and lakes in the middle part of the Awash Valley. Infection rates between 6 and 52% were found among seminomadic Afar and between 0 and 27% in agricultural groups. The highly localised distribution of vesical schistosomiasis is maintained by the distribution of the swamps, lakes and the human population and by migration patterns. On the marshy plain near Gewani significantly higher infection rates occur among Afar females than males. This is apparently due to sex differences in water contact patterns.
在阿瓦什河泛滥平原的阿法尔部落地区进行了寄生虫学和贝类学调查。埃及血吸虫感染在阿瓦什河谷中部沼泽和湖泊周边的半游牧阿法尔人群中最为普遍。半游牧阿法尔人群的感染率在6%至52%之间，农业群体的感染率在0%至27%之间。膀胱血吸虫病的高度局部性分布是由沼泽、湖泊、人口分布以及迁徙模式维持的。在格瓦尼附近的沼泽平原，阿法尔女性的感染率明显高于男性。这显然是由于接触水的模式存在性别差异。
