Aichi virus 1 (AiV-1) has been proposed as a causative agent of human gastroenteritis. In this study, raw, decanted, and treated wastewater samples from a wastewater treatment plant in an urban area of Dakar, Senegal, were collected. AiV-1 was detected in raw (70%, 14/20), decanted (68.4%, 13/19), and treated (59.3%, 16/27) samples, revealing a noticeable resistance of AiV-1 to chlorine-based treatment. Phylogenetic analysis revealed that all sequences clustered within genotype B. Our study presents the first report on the detection of AiV-1 in the environment of Dakar and constitutes indirect evidence of virus circulation in the population.

塞内加尔城市废水中爱知病毒 1 的流行率和遗传多样性

爱知病毒 1 (AiV-1) 已被提议作为人类胃肠炎的病原体。在这项研究中，收集了来自塞内加尔达喀尔市区的污水处理厂的原始、倾析和处理过的废水样本。在原始 (70%, 14/20)、倾析 (68.4%, 13/19) 和处理 (59.3%, 16/27) 样品中检测到 AiV-1，表明 AiV-1 对氯基样品具有明显的抗性治疗。系统发育分析表明，所有序列都聚集在基因型 B 内。我们的研究首次报告了在达喀尔环境中检测到 AiV-1 的情况，并构成了病毒在人群中传播的间接证据。
