Abstract：
UNASSIGNED: following the spread of the COVID-19 pandemic to Nigeria, the Federal Government of Nigeria restricted human and vehicular movements to curb the spread of the disease. This action had a negative impact on Acute Flaccid Paralysis (AFP) surveillance, with a resultant reduction in the number of AFP cases reported. This paper describes the impact of the COVID-19 pandemic on poliovirus surveillance in Nigeria and the proactive interventions by Nigeria´s polio program to mitigate the impact of COVID-19 on polio surveillance.
UNASSIGNED: nine innovative strategies were implemented in all 774 Local Government Areas (LGA) of the 36 states and Federal Capital Territory (FCT) of the country. These strategies were developed by the national surveillance officers and operationalized by sub-national surveillance officers with different strategies starting at different epidemiological weeks from week 14 to 23, 2020. Many of the strategy innovations were technology-based and included: the use of mobile phones to send the AFP case definition and video by WhatsApp or by SMS, the use of state-specific toll-free numbers and Mobile Telephone Network (MTN) (mobile service provider) CallerfeelTM to community informants (CI) who were the main targets of the interventions to increase case detection and reporting. Others included the use of abridged e-surveillance integrated supportive supervision (ISS) checklists, virtual monthly DSNO meetings, and batched AFP stool specimen transportation network.
UNASSIGNED: compared to the same period in 2019, the cumulative rate of AFP case detection and reporting had gradually declined from 39.1% in January to 16.7% before the commencement of the interventions in week 20, 2020. However, the detection and reporting increased by 57.% from week 20 to week 47 compared to the same period in 2019. This is because with COVID-19, hospital visitation dropped, and the sick remained in the communities, so the CI network was relied on to detect and report AFP cases. The cumulative proportion of AFP cases reported by community informants as of week 47 increased from 13% in 2018 to 21% in 2020. This indicates an increase of 38%. Thirty-five AFP cases were detected and reported using the MTN Caller Feel strategy, while 15 cases were reported through state-specific toll-free numbers.
UNASSIGNED: the implementation of the innovative strategies was able to mitigate the low AFP case detection and reporting observed at the initial stage of the COVID-19 pandemic. The use of technology facilitated reaching the CI network, which was more instrumental in detecting and reporting the cases.

摘要：
■在COVID-19大流行蔓延到尼日利亚之后，尼日利亚联邦政府限制人员和车辆的流动，以遏制疾病的传播。这一行动对急性弛缓性麻痹（AFP）监测产生了负面影响，导致报告的AFP病例数减少。本文介绍了COVID-19大流行对尼日利亚脊髓灰质炎病毒监测的影响，以及尼日利亚脊髓灰质炎计划的积极干预措施，以减轻COVID-19对脊髓灰质炎监测的影响。
■在36个州的所有774个地方政府区（LGA）和该国的联邦首都直辖区（FCT）实施了九项创新战略。这些策略由国家监测官员制定，并由国家以下各级监测官员在2020年第14至23周的不同流行病学周开始实施不同的策略。许多战略创新都是基于技术的，包括：使用手机通过WhatsApp或SMS发送AFP案例定义和视频，对社区线人(CI)使用特定州的免费电话号码和移动电话网络(MTN)(移动服务提供商)CallerfeelTM,这些线人是增加病例发现和报告的干预措施的主要目标.其他包括使用简化的电子监控综合支持监督(ISS)清单，虚拟每月DSNO会议，和分批AFP粪便标本运输网络。
与2019年同期相比，AFP病例检测和报告的累积率从1月份的39.1%逐渐下降到2020年第20周干预措施开始前的16.7%。然而,检测和报告增加了57。与2019年同期相比，从第20周到第47周的百分比。这是因为随着COVID-19，医院就诊人数下降了，病人留在社区里，因此依靠CI网络来检测和报告AFP病例。截至第47周，社区线人报告的AFP病例的累计比例从2018年的13％增加到2020年的21％。这表明增加了38%。使用MTNCallerFeel策略检测并报告了35例AFP病例，而15例病例是通过特定州的免费电话号码报告的。
■创新策略的实施能够减轻在COVID-19大流行初期观察到的低AFP病例检测和报告。技术的使用促进了CI网络的普及，这对检测和报告病例更有帮助。
