ABSTRACT

The detection of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) during wastewater treatment leads to concerns about whether this process may represent a focal point for the transmission of COVID-19. An epidemiological analysis, based on a COVID-19 IgG/IgM Rapid Test Cassette, performed on 134 wastewater workers from 59 wastewater treatment plants from the province of Granada (Spain) showed a seroprevalence of 8.95% in IgG for SARS-CoV-2, which is similar to the incidence rate found for the general population of the province (9.6%; 95%CI = 7.2–12.8). These findings suggest that current safety measures are sufficient for the protection of workers against SARS-CoV-2.

摘要

在废水处理过程中检测到严重急性呼吸系统综合症冠状病毒 2 (SARS-CoV-2) 导致人们担心该过程是否可能代表 COVID-19 传播的焦点。一项基于 COVID-19 IgG/IgM 快速检测盒的流行病学分析，对来自格拉纳达省（西班牙）的 59 个污水处理厂的 134 名污水处理工人进行，结果显示 SARS-CoV-2 的 IgG 血清阳性率为 8.95%，这与全省普通人群的发病率相似（9.6%；95%CI = 7.2-12.8）。这些发现表明，当前的安全措施足以保护工人免受 SARS-CoV-2 的侵害。
