背景资料：2014年3月在几内亚爆发的埃博拉病毒病已被宣布为国际关注的突发公共卫生事件。Objectives：该综述文章的目的是评估接触者追踪在埃博拉疫情中的作用，并确定卫生工作者在进行接触者追踪时所面临的挑战。在PubMed、Medline、世界卫生组织网站和Google Scholar搜索引擎中对与埃博拉疫情和接触者追踪有关的所有材料进行了广泛搜索。检索中使用的关键词包括埃博拉病毒病、西非、接触者追踪、世界卫生组织。共选择了60篇文章，并列入了discussion.Results：接触者追踪是流行病学的一个重要战略，是指那些个人谁来接触感染者的识别和诊断。它的最终目的是缩短发现和治疗传染病病例所需的时间，从而大大减少传染给随后易感个体的风险。事实上，接触者追踪仍然是一个重要的措施，因为它有助于流行病学家在遏制infection.Conclusion：接触者追踪的战略有很大的潜力，显着降低埃博拉病毒病的病例的发病率。然而，它的成功最终取决于社区和公共卫生系统之间的信任程度以及诊断和治疗服务的质量。
Background: The 2014 outbreak of Ebola virus disease which emerged in the month of March in the year 2014 in Guinea has been declared as a public health emergency of international concern.Objectives: The objectives of the review article are to assess the role of contact tracing in the Ebola outbreak and to identify the challenges faced by the health workers while performing contact tracing.Methods: An extensive search of all materials related to the Ebola outbreak and contact tracing was carried out in PubMed, Medline, World Health Organization website and Google Scholar search engines. Keywords used in the search included Ebola virus disease, West-Africa, contact tracing, World Health Organization. Overall 60 articles were selected and included in the discussion.Results: Contact tracing is an important strategy in epidemiology and refers to the identification and diagnosis of those individuals who have come in contact with an infected person. It ultimately aims to reduce the time span required to detect and treat a case of an infectious disease and hence significantly minimize the risk of transmission to the subsequent susceptible individuals. In-fact, contact tracing continues to remain an important measure, as it aids the epidemiologist in containing the infection.Conclusion: The strategy of contact tracing has a great potential to significantly reduce the incidence of cases of Ebola virus disease. However, its success is eventually determined by the level of trust between the community and the public health system and the quality of the diagnostic & treatment services.
