The 2018 cholera outbreak in Nigeria affected over half of the states in the country, and was characterised by high attack and case fatality rates. The country continues to record cholera cases and related deaths to date. However, there is a dearth of evidence on context-specific drivers and their operational mechanisms in mediating recurrent cholera transmission in Nigeria. This study therefore aimed to fill this important research gap, with a view to informing the design and implementation of appropriate preventive and control measures.
Four bibliographic literature sources (CINAHL (Plus with full text), Web of Science, Google Scholar and PubMed), and one journal (African Journals Online) were searched to retrieve documents relating to cholera transmission in Nigeria. Titles and abstracts of the identified documents were screened according to a predefined study protocol. Data extraction and bibliometric analysis of all eligible documents were conducted, which was followed by thematic and systematic analyses.
Forty-five documents met the inclusion criteria and were included in the final analysis. The majority of the documents were peer-reviewed journal articles (89%) and conducted predominantly in the context of cholera epidemics (64%). The narrative analysis indicates that social, biological, environmental and climatic, health systems, and a combination of two or more factors appear to drive cholera transmission in Nigeria. Regarding operational dynamics, a substantial number of the identified drivers appear to be functionally interdependent of each other.
The drivers of recurring cholera transmission in Nigeria are diverse but functionally interdependent; thus, underlining the importance of adopting a multi-sectoral approach for cholera prevention and control.
2018 年尼日利亚爆发的霍乱疫情影响了该国一半以上的州，其特点是高攻击率和病死率。截至目前，该国仍在报告霍乱病例和相关死亡病例。然而，关于特定背景下的驱动因素及其在调节尼日利亚反复发生的霍乱传播中的运作机制的证据仍然缺乏。因此，本研究旨在填补这一重要的研究空白，以期为设计和实施适当的预防和控制措施提供信息。
为了检索与尼日利亚霍乱传播有关的文件，我们在四个文献来源（CINAHL（Plus with full text）、Web of Science、Google Scholar 和 PubMed）和一个期刊（African Journals Online）中进行了搜索。根据预先设定的研究方案，对确定的文件的标题和摘要进行筛选。对所有合格文件进行数据提取和文献计量分析，然后进行主题和系统分析。
有 45 份文件符合纳入标准，并纳入最终分析。大多数文件是同行评议的期刊文章（89%），主要是在霍乱流行的背景下进行的（64%）。叙述性分析表明，社会、生物、环境和气候、卫生系统以及两个或多个因素的组合似乎是尼日利亚霍乱传播的驱动因素。关于运作动态，许多已确定的驱动因素似乎在功能上相互依存。
尼日利亚反复发生霍乱传播的驱动因素是多样的，但在功能上相互依存；因此，强调了采取多部门方法预防和控制霍乱的重要性。
