To assess the global prevalence of HAdV in case-patients of all ages with AGE, we conducted a systematic literature search for studies published in English during 2015–2022. We generated pooled prevalence estimates using generalized linear mixed models. Using data from 147 included articles, the overall pooled prevalence among AGE case-patients of any species of HAdV (pan-HAdV) was 5.8 % and 6.0 % for HAdV-F. The prevalence of HAdV was significantly higher among case-patients &lt; 5 years of age compared with case-patients ≥ 5 years of age (pan-HAdV: 6.6 % vs. 2.0 %, p &lt; 0.0001; HAdV-F: 8.7 % vs. 2.3 %, p = 0.04). Prevalence was significantly higher in high mortality developing countries and lowest in developed countries (pan-HAdV: 9.4 % vs. 4.0 %, p &lt; 0.0001; HAdV-F: 11.6 % vs. 3.2 %, p = 0.0003). Understanding the burden of HAdV-associated AGE may be useful for targeted interventions, including future vaccine development.</div></div>","PeriodicalId":16087,"journal":{"name":"Journal of Infection and Public Health","volume":"18 7","pages":"Article 102800"},"PeriodicalIF":4.7,"publicationDate":"2025-05-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143912985","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}
