Among children seeking care in ED or hospital settings, with confirmed RV or RV/EV single detections, hospitalization was more common with RV-A and -C than RV-B.</div></div>","PeriodicalId":15517,"journal":{"name":"Journal of Clinical Virology","volume":"179 ","pages":"Article 105806"},"PeriodicalIF":4.0,"publicationDate":"2025-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144221011","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
