the number of wild poliomyelitis cases, worldwide, dropped from 350,000 cases in 1988 to 33 in 2018. Acute flaccid paralysis (AFP) surveillance is a key strategy toward achieving global polio eradication. The 2014 Ebola virus disease (EVD) epidemic in West Africa infected over 28,000 people and had devastating effects on health systems in Guinea, Liberia, and Sierra Leone. We sought to assess the effects of the 2014 Ebola outbreak on AFP surveillance in Guinea and Liberia.
a retrospective cross-sectional analysis was performed for Guinea and Liberia to evaluate EVD´s impact on World Health Organization (WHO) AFP surveillance performance indicators during 2012-2015.
both Guinea and Liberia met the WHO target non-polio AFP incidence rate nationally, and generally sub-nationally, prior to the EVD outbreak; rates decreased substantially during the outbreak in seven of eight regions in Guinea and 11 of 15 counties in Liberia. Throughout the study period, both Guinea and Liberia attained appropriate overall targets nationally for "notification" and "stool adequacy" indicators, but each country experienced periods of poor regional/county-specific indicator performance.
these findings mirrored the negative effect of the Ebola outbreak on polio elimination activities in both countries and highlights the need to reinforce this surveillance system during times of crisis.
全球野生脊髓灰质炎病例数量从 1988 年的 35 万例降至 2018 年的 33 例。急性弛缓性麻痹（AFP）监测是实现全球消灭脊髓灰质炎的关键策略。2014 年西非埃博拉病毒病（EVD）疫情感染人数超过 28000 人，对几内亚、利比里亚和塞拉利昂的卫生系统造成了毁灭性影响。我们试图评估 2014 年埃博拉疫情对几内亚和利比里亚 AFP 监测的影响。
对几内亚和利比里亚进行回顾性横断面分析，以评估 2012-2015 年期间 EVD 对世界卫生组织（WHO）AFP 监测绩效指标的影响。
在埃博拉疫情爆发之前，几内亚和利比里亚均符合 WHO 全国非脊髓灰质炎 AFP 发病率目标，总体上符合次国家级目标；在几内亚的八个地区中有七个地区和利比里亚的 15 个县中有 11 个地区的发病率在疫情爆发期间大幅下降。在整个研究期间，几内亚和利比里亚在国家一级均达到了“通知”和“粪便充足性”指标的总体适当目标，但两国都经历了地区/县特定指标表现不佳的时期。
这些发现反映了埃博拉疫情对两国消除脊髓灰质炎活动的负面影响，突出了在危机时期加强这一监测系统的必要性。
