导言：目前，估计有三分之二的世界人口缺水。截至2015年，发展中国家每五个人中就有一个无法获得足够清洁的饮用水。为了共享有限的资源，发展中国家的城市不定期地分配水。这些城市的居民寻找替代水源来补充供应不足的水。其中一些替代水源对人类饮用是不安全的，导致水传播疾病的风险增加。非洲占全球报告的腹泻病例的53%，受污染的饮用水是主要的传播来源。腹泻、霍乱、伤寒、阿米巴病、痢疾、胃肠炎、隐孢子虫、环孢子虫病、贾第鞭毛虫病、麦地那龙线虫病和轮状病毒等水传播疾病是一个主要的公共卫生问题。这项范围审查的主要目的是绘制现有证据图，以了解非洲城市居民的水源，以及清洁水充足与非洲城市水传播疾病之间的关系。方法和分析：搜索战略将确定发表在科学期刊和报告上的与截至2014年人口超过50万的非洲城市直接相关的研究，以及关于十种新出现的水传播疾病的研究，这些疾病是腹泻、霍乱、伤寒、阿米巴病、痢疾、胃肠炎、隐孢子虫病、环孢子虫病、贾第鞭毛虫病、麦地那龙线虫病和轮状病毒。伦理和传播：这一范围审查不需要任何正式的伦理批准。这一发现将发表在同行评议的期刊上。
Introduction: Currently, an estimated two thirds of the world population is water insufficient. As of 2015, one out of every five people in developing countries do not have access to clean sufficient drinking water. In an attempt to share the limited resource, water has been distributed at irregular intervals in cities in developing countries. Residents in these cities seek alternative water sources to supplement the inadequate water supplied. Some of these alternative sources of water are unsafe for human consumption, leading to an increased risk in water-borne diseases. Africa contributes to 53% of the diarrheal cases reported globally, with contaminated drinking water being the main source of transmission. Water-borne diseases like diarrhea, cholera, typhoid, amoebiasis, dysentery, gastroenteritis, cryptosporidium, cyclosporiasis, giardiasis, guinea worm and rotavirus are a major public health concern. The main objective of this scoping review is to map the available evidence to understand the sources of water among residents in cities in Africa and the relationship between clean water sufficiency and water-borne diseases in urban Africa. Methods and analysis: The search strategy will identify studies published in scientific journals and reports that are directly relevant to African cities that have a population of more than half a million residents as of 2014 AND studies on the ten emerging water-borne diseases, which are diarrhea, cholera, typhoid, amoebiasis, dysentery, gastroenteritis, cryptosporidium, cyclosporiasis, giardiasis, guinea worm and rotavirus. Ethics and dissemination: This scoping review did not require any formal ethical approval. The findings will be published in a peer-reviewed journal.
