A population-based survey on trachoma was carried out in Jimma zone. The survey showed that trachoma is hyperendemic: of 7,423 people examined, 33.02% had signs of trachoma, 28.9% of males and 37.01% of females; 26.13% of the urban and 34.09% of the rural population had clinical signs of trachoma. Active trachoma (TF/TI) was seen in 24.5% of the study population (an estimated half million people). The prevalence of signs of active trachoma among children 0-10 years of age was 35.7%. Blinding trachoma (CO/TT) was seen in 3.81% of the population: 6.86% of the female population aged 15 years had trichiasis and/or entropion. Both active and critical trachoma were significantly associated with the female gender (P < 0.0000001 for each), living in rural areas (P < 0.0001 for each type), parental illiteracy (P < 0.0000001 for each) and absence of a latrine (P < 0.01 for each). Shorter distance of the household water supply was associated with a higher prevalence of both active and cicatricial trachoma. This was significant only for cases of active trachoma living in households within 16 to 30 minutes walking distance from the water source (P < 0.03). An estimated 17000 people in the zone are blind; 3500 of these from trachoma. About 52,000 people are in danger of blindness from trichiasis. Primary eye care activities such as promoting health education (face washing) among community members, especially women and children, mass chemotherapy for trachoma, training of health workers and establishment of community-based surgical services are recommended. These are to be executed by the Zonal Health Department in close collaboration with the community, governmental and non-governmental organisations.
在吉姆马地区开展了一项基于人群的沙眼调查。调查显示,沙眼为高度流行:在接受检查的7423人中,33.02%有沙眼体征,男性为28.9%,女性为37.01%;城市人口中有26.13%、农村人口中有34.09%有沙眼临床体征。在24.5%的研究人群(估计50万人)中发现了活动性沙眼(TF/TI)。0至10岁儿童中活动性沙眼体征的患病率为35.7%。在3.81%的人群中发现了致盲性沙眼(CO/TT):15岁女性人群中有6.86%患有倒睫和/或睑内翻。活动性沙眼和重度沙眼均与女性性别(每种情况P<0.0000001)、居住在农村地区(每种类型P<0.0001)、父母文盲(每种情况P<0.0000001)以及没有厕所(每种情况P<0.01)显著相关。家庭供水距离较短与活动性沙眼和瘢痕性沙眼的患病率较高有关。这仅在居住在距水源步行16至30分钟距离内的家庭中的活动性沙眼病例中具有统计学意义(P<0.03)。该地区估计有17000人失明;其中3500人因沙眼失明。约52000人有因倒睫致盲的危险。建议开展初级眼保健活动,如在社区成员中,特别是妇女和儿童中促进健康教育(洗脸)、沙眼群体化疗、培训卫生工作者以及建立社区外科服务。这些活动将由地区卫生部门与社区、政府和非政府组织密切合作执行。
