Anthrax outbreaks in the humans-livestock and wildlife interface areas of northern Tanzania: a retrospective review 2006 - 2016

BACKGROUND: Anthrax outbreaks in Tanzania have been reported from the human, livestock and wildlife sectors over several years, and is among the notifiable diseases. Despite frequent anthrax outbreaks, there is no comprehensive dataset indicating the magnitude and distribution of the disease in susceptible species. This study is a retrospective review of anthrax outbreaks from the human, livestock, and wildlife surveillance systems from 2006 to 2016. The objectives were to identify hotspot districts, describe anthrax epidemiology in the hotspot areas, evaluate the efficiency of the anthrax response systems and identify potential areas for further observational studies. METHODS: We prepared a spreadsheet template for a retrospective comprehensive record review at different surveillance levels in Tanzania. We captured data elements including demographic characteristics of different species, the name of health facility, and date of anthrax diagnosis. Also, we collected data on the dat...研究背景： 多年来，坦桑尼亚先后报告了发生在人类健康、家畜养殖及野生动物保护领域的炭疽（Anthrax）疫情，该病属于法定报告传染病范畴。尽管炭疽疫情频发，但目前尚无全面数据集能够阐明该疾病在易感物种中的流行规模与空间分布特征。本研究对2006年至2016年坦桑尼亚人类、家畜及野生动物监测系统中的炭疽疫情数据开展回顾性分析。研究目的如下：识别疫情热点区县，阐明热点区域的炭疽流行病学特征，评估炭疽疫情应对体系的运行效率，并明确后续可开展观察性研究的潜在领域。 研究方法： 我们针对坦桑尼亚不同监测层级的炭疽疫情回顾性全面资料审查工作，设计了专用电子表格模板。收集的数据条目涵盖不同物种的种群统计学特征、医疗机构名称以及炭疽诊断日期。此外，我们还收集了有关……的数据。
