Four groups, each with seven experts and a medical writer, were formed to discuss epidemiology and diagnosis, risk groups, vaccines, and monoclonal antibodies (mABs). Predefined questions, formulated by a team of four experts, were discussed within each group, and consensus was reached on the answers. These responses were then analyzed and organized into recommendations based on national and international evidence.</div></div><div><h3>Results</h3><div>Evidence-based recommendations for epidemiological surveillance, diagnosis, and prevention of RSV infection were proposed. Future perspectives regarding the usefulness of new vaccines and passive immunoprophylaxis were analyzed.</div></div><div><h3>Conclusions</h3><div>Timely identification of at-risk populations, diagnosis and treatment of RSV infection, and particularly the rational use of mABs and vaccines are key strategies to reduce the clinical and epidemiological burden of RSV infection.</div></div>","PeriodicalId":8318,"journal":{"name":"Archives of Medical Research","volume":"56 4","pages":"Article 103183"},"PeriodicalIF":4.7,"publicationDate":"2025-02-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143445344","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
