分析了近两年来发表的有关水传播病毒发生的相关研究，发现大多数研究是在地表沃茨和废水中进行的。通过应用，主要是，负电性过滤或超滤结合聚乙二醇沉淀，离心或离心超滤，而对于废水，大多数作者使用絮凝/沉淀从地表水样品中浓缩病毒。主要创新包括整体过滤/色谱和超滤为基础的新方法，以及在现场部署的方法。考虑到未来气候变化的影响，需要对地下水，海水和再生水中的病毒发生进行更多的研究，并考虑到未来的法规，包括水基质中病毒参数的分析，需要标准化的方法。
Relevant studies on waterborne viral occurrence published in the past 2 years have been analyzed showing that most of them were performed in surface waters and wastewater. Viruses were concentrated from surface water samples by applying, mainly, electronegative filtration or ultrafiltration combined with polyethyleneglycol precipitation, centrifugation, or centrifugal ultrafiltration, whereas for wastewater, most authors used flocculation/precipitation. Main novelties include monolithic filtration/chromatography and ultrafiltration-based new approaches as well as methods deployable in the field. Considering future climate change impacts, more studies on viral occurrence in groundwater, seawater, and reclaimed water are needed as well as standardized methods in view of future regulations comprising analysis of viral parameters in water matrices.
