有记录以来最大规模的埃博拉病毒病疫情始于 2014 年 3 月；截至 2015 年 7 月，疫情仍在 3 个主要受影响国家继续发生：几内亚、利比里亚和塞拉利昂。控制工作包括追踪接触者，以加快识别可疑病例中的病毒。我们利用有关病例患者及其接触者的国家和地方数据，检查了 2014 年 9 月 20 日至 12 月 31 日期间在几内亚 2 个省的接触者追踪活动。结果显示，不到三分之一的病例（28.3%和31.1%）在病例识别前登记为接触者；大约三分之二（61.1% 和 67.7%）没有注册联系人。疑似病例患者的隔离时间并非即时（金迪亚和法拉纳的中位时间分别为 5 天和 3 天），二次发病率因与源病例患者接触者的关系以及接触者的病例类型而异。需要更全面的接触者追踪工作来加强对这一流行病的控制。
The largest recorded Ebola virus disease epidemic began in March 2014; as of July 2015, it continued in 3 principally affected countries: Guinea, Liberia, and Sierra Leone. Control efforts include contact tracing to expedite identification of the virus in suspect case-patients. We examined contact tracing activities during September 20-December 31, 2014, in 2 prefectures of Guinea using national and local data about case-patients and their contacts. Results show less than one third of case-patients (28.3% and 31.1%) were registered as contacts before case identification; approximately two thirds (61.1% and 67.7%) had no registered contacts. Time to isolation of suspected case-patients was not immediate (median 5 and 3 days for Kindia and Faranah, respectively), and secondary attack rates varied by relationships of persons who had contact with the source case-patient and the type of case-patient to which a contact was exposed. More complete contact tracing efforts are needed to augment control of this epidemic.
