The Somali Region of Ethiopia has been affected by drought for several years. Drought conditions have led to food and water scarcity and a humanitarian crisis in the region. In January 2017, an outbreak of acute watery diarrhea (AWD) was declared in the region. AWD prevention and control activities include strengthening water, sanitation, and hygiene (WASH) services. Access to safe drinking water is critical in preventing transmission of AWD and chlorine is an effective chemical to disinfect water supplies. The US Centers for Disease Control and Prevention collaborated with the WASH Cluster and the United Nations Children's Fund, Ethiopia, to provide technical assistance to the Somali Regional Water Bureau to improve chlorination of drinking water supplies and quickly assess water quality improvements in Jijiga town, Fafan Zone. Timely sharing of surveillance and case investigation data allowed for the identification of gaps within the water supply system in Jijiga and implementation of centralized and decentralized chlorination interventions and monitoring systems. Pilot use of a rapid assessment to determine residual chlorine levels at various points in the city helped improve chlorination intervention impact. This work illustrates that rapid community-level water quality improvements can be implemented and assessed quickly to improve interventions during outbreaks.

埃塞俄比亚索马里地区爆发急性水样腹泻,提高了氯化水平,并快速评估了水质

埃塞俄比亚的索马里地区遭受干旱影响已有数年。干旱条件导致该地区粮食和水短缺以及人道主义危机。2017年1月,该地区宣布爆发急性水样腹泻(AWD)。AWD预防和控制活动包括加强水,环境卫生(WASH)服务。获得安全饮用水对于防止AWD传播至关重要,而氯是消毒供水的有效化学品。美国疾病控制和预防中心与WASH集群和埃塞俄比亚联合国儿童基金会合作,向索马里地区水务局提供技术援助,以改善饮用水供应的氯化作用,并快速评估法范吉吉加镇的水质改善情况区。及时共享监视和案件调查数据有助于查明吉吉加供水系统内部的差距,并实施集中式和分散式加氯干预措施和监测系统。试点性使用快速评估来确定城市中各个地点的残留氯含量有助于改善氯化干预的影响。这项工作表明,可以快速实施社区级水质改善并进行评估,以改善暴发期间的干预措施。试点性使用快速评估来确定城市中各个地点的残留氯含量有助于改善氯化干预的影响。这项工作表明,可以快速实施社区级水质改善并进行评估,以改善暴发期间的干预措施。试点性使用快速评估来确定城市中各个地点的残留氯含量有助于改善氯化干预的影响。这项工作表明,可以快速实施社区级水质改善并进行评估,以改善暴发期间的干预措施。
