To determine the burden of trachoma and its related risk factors amongst the native population of Car-Nicobar Island in India.
Rapid assessment for trachoma was conducted in ten villages of Car-Nicobar Island according to standard WHO guidelines. An average of 50 children aged 1-9 years were assessed clinically for signs of active trachoma and facial cleanliness in each village. Additionally, all adults above 15 years of age in these households were examined for evidence of trachomatous trichiasis and corneal opacity. Environmental risk factors contributing to trachoma like limited access to potable water & functional latrine, presence of animal pen and garbage within the Nicobari hut were also noted in all villages.
Out of a total of fifteen villages in Car-Nicobar Island, ten villages were selected for trachoma survey depending on evidence of socio-developmental indicators like poverty and decreased access to water, sanitation and healthcare facilities. The total population of the selected clusters was 7277 in the ten villages. Overall, 251 of 516 children (48.6%;CI: 46.5-55.1) had evidence of follicular stage of trachoma and 11 children (2.1%;CI:1.0-3.4) had evidence of inflammatory stage of trachoma. Nearly 15%(CI:12.1-18.3) children were noted to have unclean faces in the ten villages. Trachomatous trichiasis was noted in 73 adults (1.0%;CI:0.8-1.2). The environmental sanitation was not found to be satisfactory in the surveyed villages mainly due to the co-habitance of Nicobari people with domestic animals like pigs, hens, goats, dogs, cats etc in most (96.4%) of the households.
Active trachoma and trachomatous trichiasis was observed in all the ten villages surveyed, wherein trachoma control measures are needed.
在印度的安达曼-尼科巴群岛的原住民中，确定沙眼及其相关危险因素的负担。
根据世界卫生组织的标准指南，对安达曼-尼科巴群岛的 10 个村庄进行了快速评估。在每个村庄，平均评估了 50 名 1-9 岁的儿童的活动性沙眼和面部清洁状况。此外，对这些家庭中所有 15 岁以上的成年人进行了沙眼性倒睫和角膜混浊的检查。还记录了所有村庄中导致沙眼的环境危险因素，如饮用水和功能厕所有限、存在动物围栏和垃圾等。
在安达曼-尼科巴群岛的 15 个村庄中，根据贫困和获得水、卫生和医疗设施机会减少等社会发展指标的证据，选择了 10 个村庄进行沙眼调查。所选村庄的总人口为 7277 人。总的来说，516 名儿童中有 251 名（48.6%；CI：46.5-55.1）有滤泡性沙眼的证据，11 名（2.1%；CI：1.0-3.4）有活动性沙眼的证据。在这 10 个村庄中，近 15%（CI：12.1-18.3）的儿童面部不干净。在 73 名成年人（1.0%；CI：0.8-1.2）中发现了沙眼性倒睫。由于在大多数（96.4%）家庭中，尼科巴人与猪、母鸡、山羊、狗、猫等家畜共同生活，调查村庄的环境卫生状况不佳。
在所调查的 10 个村庄中均观察到活动性沙眼和沙眼性倒睫，需要采取沙眼控制措施。
