Wastewater surveillance offers a rapid evaluation of SARS-CoV-2 transmission in a community. We describe how a community group, the Yarmouth Wastewater Testing Team (YWTT), in Yarmouth, Maine, (population 8,990) utilized an asset-based community design framework to organize and manage a program to monitor SARS-CoV-2 RNA concentrations. From September 22, 2020 through June 8, 2021, the YWTT disseminated weekly reports of the wastewater results and reported COVID-19 cases within the Yarmouth postal code. After high and increasing SARS-CoV-2 RNA concentrations, the YWTT issued two community advisories to encourage extra care to reduce exposure. Correlations between SARS-CoV-2 RNA concentrations and COVID-19 cases were stronger the week after sampling, and the average of the COVID-19 cases during the week of sampling and the following week, indicating that surveillance provided advance notice of cases. A 10% increase in SARS-CoV-2 RNA concentrations was associated with a 13.29% increase in the average number of weekly reported cases of COVID-19 during the week of sampling and the following week (R2 = 0.42; p < 0.001). Adjusting for viral recovery (December 21, 2020 through June 8, 2021), improved R2 from 0.60 to 0.68. Wastewater surveillance was an effective tool for the YWTT to quickly respond to viral transmission.
污水监测可快速评估社区中 SARS-CoV-2 的传播情况。我们描述了缅因州雅茅斯社区的一个团体，即雅茅斯污水检测团队（YWTT），如何利用基于资产的社区设计框架来组织和管理监测 SARS-CoV-2 RNA 浓度的项目。从 2020 年 9 月 22 日到 2021 年 6 月 8 日，YWTT 每周发布污水检测结果报告，并报告雅茅斯邮政编码内的 COVID-19 病例。在 SARS-CoV-2 RNA 浓度升高且持续增加后，YWTT 发布了两条社区通告，鼓励居民加强防护以减少暴露。污水监测结果与 COVID-19 病例之间的相关性在采样后一周最强，采样周和随后一周的 COVID-19 病例平均水平也表明监测可提前发现病例。SARS-CoV-2 RNA 浓度增加 10%，则采样周和随后一周报告的 COVID-19 病例平均数量增加 13.29%（R2 = 0.42；p < 0.001）。考虑到病毒回收率（2020 年 12 月 21 日至 2021 年 6 月 8 日），调整后 R2 从 0.60 提高到 0.68。污水监测对 YWTT 快速应对病毒传播是一种有效的工具。
