Trachoma (Chlamydia-triggered blinding infection) provoked irreversible visual impairment in about 8 million people in 2011, and the prevalence among children with dirty faces is more than three fold that among children with clean faces. In 250 villages with a high prevalence of trachoma (Kolofata district, Far North Region, Cameroon), the lack of water for facial cleanliness was reported during trachoma awareness campaigns. The objective of this study was to determine if the lack of water was linked with the absence of means to dig wells.
Wells, waterholes, motorcycles, irrigation pumps, electricity, goats and oxen, cell phones and distance from waterholes were recorded in January 2011 in 50 randomized villages of Kolofata's district.
The number of villages with <25 goats and <5 oxen was 0 and the number of adults owning <1 goat was 0. The cost of a pail of water was 0.01 USD. Motorcycles, cell phones and televisions have been reported in more than 66% of villages. The cost for the construction of lined shaft wells ranged between 15-35 goats and 0.5-3 oxen; the cost for drinking water wells ranged between 50-200 goats and 3-30 oxen.
No link between the means for digging wells at the village level and access to water was found. Social solidarity, which refers to a social debt owed by each person to his/her group, should be added to training guides to gauge its ability to release people from the dead end of having to wait for external assistance to gain access to water.
2011年,沙眼(由衣原体引发的致盲性感染)致使约800万人出现不可逆的视力损害,面部不洁儿童的患病率是面部清洁儿童的三倍多。在沙眼高发的250个村庄(喀麦隆远北地区科洛法塔区),沙眼宣传活动期间报告称缺乏用于面部清洁的水。本研究的目的是确定缺水是否与缺乏打井手段有关。
2011年1月,在科洛法塔区50个随机选取的村庄记录了水井、水坑、摩托车、灌溉泵、电力、山羊和牛、手机以及与水坑的距离。
山羊数量少于25只且牛数量少于5头的村庄数量为0,拥有山羊数量少于1只的成年人数量为0。一桶水的成本为0.01美元。超过66%的村庄报告有摩托车、手机和电视。衬砌竖井的建设成本在15 - 35只山羊和0.5 - 3头牛之间;饮用水井的成本在50 - 200只山羊和3 - 30头牛之间。
未发现村庄层面的打井手段与获取水源之间存在关联。社会团结,即每个人对其群体所负的社会债务,应添加到培训指南中,以评估其能否使人们摆脱必须等待外部援助才能获取水源的困境。
