Almost 19% of the GDP of Ethiopia results from livestock production. Ruminants, in particular, form the majority of the national herd and are a critical source of income for smallholder farmers. Infectious diseases have been identified as a major cause of reduced livestock productivity in low- and middle-income countries (LMICs); therefore, a sound and comprehensive understanding of the relevant evidence would be beneficial in order to enable decision making on disease control policies. However, livestock disease data from sub-Saharan Africa is variable and disparate, which poses a challenge for evidence synthesis. This paper describes a protocol for a systematic mapping review of the recent available evidence on ruminant disease prevalence and associated mortality in Ethiopia. Literature sources will be identified using database search strategies. The titles, abstracts and, subsequently, full texts will be screened for inclusion based on predefined eligibility criteria. Specific data will be extracted and a preliminary qualitative assessment of the evidence will be performed using predefined indicators. The planned systematic map will be the first to provide a large-scale overview of the available ruminant disease evidence in Ethiopia; the final output will be an interactive dashboard tool to inform critical stakeholders in policy and research.

为反刍动物传染病频率和疾病相关死亡率的最新证据制定系统绘图审查方案：以埃塞俄比亚为例

埃塞俄比亚近 19% 的 GDP 来自畜牧业生产。尤其是反刍动物，占全国畜群的大部分，是小农的重要收入来源。传染病已被确定为低收入和中等收入国家 (LMIC) 牲畜生产力下降的主要原因；因此，对相关证据有充分而全面的了解将有助于做出疾病控制政策的决策。然而，来自撒哈拉以南非洲的牲畜疾病数据是多变和不同的，这对证据合成提出了挑战。本文描述了对埃塞俄比亚反刍动物疾病流行率和相关死亡率最近可用证据进行系统绘图审查的协议。文献来源将使用数据库搜索策略进行识别。标题、摘要以及随后的全文将根据预定义的资格标准进行筛选以纳入。将提取特定数据，并使用预定义的指标对证据进行初步定性评估。计划中的系统地图将是第一个提供埃塞俄比亚现有反刍动物疾病证据的大规模概览；最终产出将是一个交互式仪表板工具，用于为政策和研究中的关键利益攸关方提供信息。计划中的系统地图将是第一个提供埃塞俄比亚现有反刍动物疾病证据的大规模概览；最终产出将是一个交互式仪表板工具，用于为政策和研究中的关键利益攸关方提供信息。计划中的系统地图将是第一个提供埃塞俄比亚现有反刍动物疾病证据的大规模概览；最终产出将是一个交互式仪表板工具，用于为政策和研究中的关键利益攸关方提供信息。
