the COVID-19 pandemic has spread across all countries in Africa, with much of the model forecasting disastrous results owing to weak health services and political uncertainty. In Niger, an adaptive solution to the COVID-19 pandemic has been implemented by community-based surveillance system (CBS) to complement passive case-finding in health systems.
the CBS program was designed to use the current CBS polio network spanning 37 health districts in six regions. Between April and November 2020, 150 community health workers (CHWs) were equipped to improve integrated disease surveillance and response (IDSR) preparedness and response to the COVID-19 pandemic. We retrospectively analysed the health data of the National Health Information System to describe the effect of CBS in COVID-19 surveillance.
overall, trained CHWs were able to raise awareness among 2,681,642 persons regarding COVID-19 preventions and controls strategies. They reported 143 (84%) valid alerts resulting in two positive COVID-19 cases missing in the community. In addition, CHWs added to the contact tracing of 37 individuals and informed about the deaths in the community.
community-based surveillance improved COVID-19 response in Niger. Logistic assistance and ongoing training are the foundations for increasing and sustaining the sensitivity of CBS systems in response to the COVID-19 pandemic to deter hotspots across countries.
COVID-19 疫情已在非洲所有国家蔓延，由于卫生服务薄弱和政治不稳定，许多模型预测结果将惨不忍睹。在尼日尔，通过社区为基础的监测系统（CBS）实施了一种适应性解决方案，以补充卫生系统中的被动病例发现，从而应对 COVID-19 疫情。
CBS 计划旨在利用当前覆盖六个地区 37 个卫生区的脊髓灰质炎 CBS 网络。2020 年 4 月至 11 月期间，150 名社区卫生工作者（CHW）接受了培训，以提高综合疾病监测和应对（IDSR）准备工作，并应对 COVID-19 疫情。我们回顾性地分析了国家卫生信息系统的卫生数据，以描述 CBS 在 COVID-19 监测中的作用。
总体而言，经过培训的 CHW 能够向 2681642 人宣传 COVID-19 预防和控制策略。他们报告了 143 起（84%）有效警报，导致社区中漏报了两例 COVID-19 阳性病例。此外，CHW 还协助追踪了 37 名接触者，并通报了社区中的死亡情况。
社区为基础的监测提高了尼日尔对 COVID-19 的应对能力。后勤援助和持续培训是提高和维持 CBS 系统对 COVID-19 疫情应对敏感性的基础，以防止各国出现热点。
