The effects of viral gastroenteritis are more devastating in children than in any other age category. Thus, children exposed to the consumption of low quality water are at an increased risk of infection, especially in regions where sanitation is inadequate. The present study aimed to provide a survey of the occurrence of representative enteric viruses: human adenovirus (HAdV), human enteroviruses (hEV), and genogroup A rotavirus (GARV) in tap water samples collected in public schools located at six municipalities of Rio Grande do Sul, southern Brazil. Seventy-three schools were included in the study and tap water samples were analyzed by conventional PCR for the presence of HAdV, hEV, and GARV genomes. hEV showed the highest detection rate (27.4%), followed by HAdV (23.3%), and GARV (16.4%). New approaches to water monitoring should be considered to promote a better water quality and reduce the risk of waterborne diseases, especially considering drinking water to be served to vulnerable individuals.
病毒性肠胃炎对儿童的影响比对其他任何年龄段的人都更具破坏性。因此，饮用低质量水的儿童感染风险增加，尤其是在卫生条件不足的地区。本研究旨在对巴西南部南里奥格兰德州六个市的公立学校采集的自来水样本中代表性肠道病毒的发生情况进行调查：人类腺病毒（HAdV）、人类肠道病毒（hEV）和A组轮状病毒（GARV）。该研究纳入了73所学校，并通过常规PCR分析自来水样本中HAdV、hEV和GARV基因组的存在情况。hEV的检出率最高（27.4%），其次是HAdV（23.3%）和GARV（16.4%）。应考虑采用新的水监测方法来改善水质并降低水传播疾病的风险，特别是考虑到饮用水要供应给弱势群体。
