Epidemiological studies were carried out among 180 randomly chosen settler and 180 non-settler households in the three resettlement schemes of Kishe, Gera and Didessa located in river valleys and highland areas of Illubabor Administrative Region in western Ethiopia. Up to 49% of the indigenous populations (in Kishe) and 0.9% of the settlers had onchocerciasis, with a mean density of 13.6 filariae per slide/skin snip for indigenous people and 9.4 for settlers. Onchocerciasis prevalence rates were higher in males than females and were highest in the 20-59 age group. In the Kishe scheme, rates were inversely related to distance between residences and probable forest/stream habitat of Simulium damnosum. No onchocerciasis transmission appears to occur in the Gera scheme at 1,950 meters altitude, apparently due to the absence of suitable vectors. Eight of 622 (1.2%) persons had malaria (P. vivax and P. falciparum). The most common man-biting anophelines were A. gambiae and A. funestus. No human trypanosomiasis cases were found but high livestock mortality was reported by local populations in the lowland schemes of Kishe and Didessa.
在埃塞俄比亚西部伊鲁巴博尔行政区河谷和高地地区的基舍、盖拉和迪德萨三个重新安置点,对180个随机选取的定居家庭和180个非定居家庭进行了流行病学研究。在基舍,高达49%的当地人口患有盘尾丝虫病,而定居者中这一比例为0.9%,当地人群每玻片/皮肤切片的丝虫平均密度为13.6条,定居者为9.4条。盘尾丝虫病的患病率男性高于女性,在20 - 59岁年龄组中最高。在基舍安置点,患病率与居住地和致倦库蚊可能的森林/溪流栖息地之间的距离呈负相关。在海拔1950米的盖拉安置点似乎没有盘尾丝虫病传播,显然是因为没有合适的病媒。622人中有8人(1.2%)感染疟疾(间日疟原虫和恶性疟原虫)。最常见的叮人按蚊是冈比亚按蚊和致倦库蚊。未发现人类锥虫病病例,但在基舍和迪德萨的低地安置点,当地居民报告牲畜死亡率很高。
