背景资料：在2014-2015年西非疫情中，接触者追踪的延迟和无效导致了埃博拉病毒病（EVD）的广泛传播。了解和应对实施和管理接触者追踪所面临的挑战对于阻止EVD传播和预防未来大规模EVD暴发至关重要。方法：对美国疾病控制和预防中心在受影响的西非国家塞拉利昂、几内亚、利比里亚、塞内加尔、尼日利亚、2014年9月至12月，马里。对每个国家的两名工作人员进行了访谈。五个最常提到的接触者追踪challenges.Results：挑战已经在接触者追踪过程中的每一个步骤，从实施到管理，包括识别，定位和登记的接触者，以及管理人员和确保接触者追踪性能是显而易见的。在所有受影响的西非国家观察到的共同主题包括恐惧、耻辱和社区对EVD的误解。已经克服这些挑战，确保立即和全面的接触者追踪的国家，已成功地阻止EVD的传播。结论：解决西非EVD疫情中接触者追踪实施和管理的挑战对于阻止持续传播至关重要。由Elsevier Ltd代表国际传染病学会出版。
Background: Delayed and ineffective contact tracing contributed to the extensive transmission of Ebola virus disease (EVD) in the 2014-2015 West African outbreak. Understanding and addressing the challenges to implementing and managing contact tracing is essential to stopping EVD transmission and preventing large-scale EVD outbreaks in the future.Methods: Interviews were conducted with United States Centers for Disease Control and Prevention staff members engaged in contact tracing activities in the affected West African countries of Sierra Leone, Guinea, Liberia, Senegal, Nigeria, and Mali from September through December 2014. Two staff members from each country were interviewed. The five most frequently cited contact tracing challenges were identified.Results: Challenges have been evident in every step of the contact tracing process from implementation to management, including identifying, locating, and enrolling contact-persons, as well as managing personnel and ensuring contact tracing performance. Common themes observed in all of the affected West African countries have included fear, stigma, and community misperceptions regarding EVD. Countries that have overcome these challenges, ensuring immediate and comprehensive contact tracing, have been successful in halting EVD transmission.Conclusions: Addressing challenges to contact tracing implementation and management in the West African EVD outbreak is essential to stopping ongoing transmission.
