Incidence rates (IRs) per 100,000 were calculated. Seasonality was analysed using Poisson regression, and antimicrobial susceptibility was determined by EUCAST disc diffusion.</div></div><div><h3>Results</h3><div>In total, 9470 iBHS cases were identified. Annual IRs increased from 2.6 to 9.4 for iGAS, 2.5 to 4.9 for iGBS, 1.4 to 4.8 for iGCS, and 3.1 to 8.5 for iGGS. iGAS exhibited marked seasonality, peaking in February and troughing in September (peak-to-trough ratio 3.2). Incidence declined during the COVID-19 pandemic but rebounded in 2023. No seasonality was observed for iGBS, iGCS, or iGGS. Incidences were highest in males and older adults, except iGBS, which showed a bimodal distribution. Recurrent infections occurred in 5.4% of cases, predominantly with iGGS and iGCS. All isolates were penicillin susceptible, but erythromycin and clindamycin resistance increased in iGBS and iGGS.</div></div><div><h3>Conclusions</h3><div>The rising incidence of iBHS, particularly iGAS resurgence and increasing resistance, highlights the need for continued surveillance.</div></div>","PeriodicalId":50180,"journal":{"name":"Journal of Infection","volume":"91 2","pages":"Article 106559"},"PeriodicalIF":11.9,"publicationDate":"2025-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144719042","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
