For 6,352 samples, we determined the G and/or P genotypes through sequencing of the genes encoding the outer capsid proteins VP7 and VP4.ResultsBefore the COVID-19pandemic, we received on average 622 samples per rotavirus epidemiological year, which decreased to 114 and 111 samples during the two pandemic rotavirus epidemiological years, followed by a peak of 1,048 samples in the first post-pandemic year. Notably, the proportion of cases in the age group 2-5-years increased from 20.3% before to 33% after the pandemic (p < 0.001). Over the 14-year study period, the most common genotypes were G2P[4], G3P[8] and G9P[8]. Post-pandemic data show an unusually strong dominance of the equine-like G3P[8] genotype which carried a DS-1-like genotype constellation in the period 2021 to 2023. Additionally, vaccinated individuals were significantly overrepresented among patients infected with the equine-like VP7 carrying G3P[8] rotavirus compared with other genotypes, including typical human VP7 G3P[8].ConclusionDespite the presence of typical yearly genotype fluctuations, several epidemiological changes were associated with the COVID-19 pandemic, including the unusual dominance of an emerging rotavirus strain against which current vaccines may be less effective. It is essential to closely monitor this strain to determine if the phenomenon is temporary.</p>","PeriodicalId":12161,"journal":{"name":"Eurosurveillance","volume":"30 12","pages":""},"PeriodicalIF":9.9,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11951416/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143742172","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Healthcare-associated infections refer to infections acquired in a hospital or another healthcare setting.AimThis systematic review aims to explore determinants of healthcare-associated malaria (HAM) cases.MethodThis review follows the PRISMA guidelines and was registered in PROSPERO (CRD42022309701). We searched five databases for publications on HAM cases published between 1 January 2000 and 7 December 2023. We initiated a data call for HAM cases to public health authorities from 37 European countries. We performed a backward and forward search, reviewed health authorities' websites, performed searches on Google and the European Scientific Conference on Applied Infectious Disease Epidemiology (ESCAIDE) conference abstracts book.ResultsWe identified 37 studies on HAM comprising 55 HAM cases, of which 35 (64%) were infected in Europe, primarily in Spain (nine cases), France and Italy (seven cases each). All cases were infected with <i>Plasmodium falciparum</i> except one individual. Fifty HAM cases were hospital inpatients and five were healthcare workers. Five patients died. Flushing of vascular catheters with contaminated heparin/saline solution and manipulation of intravenous catheters were the most frequently reported procedures leading to infection among patients.ConclusionsWhile rare, HAM transmission can be fatal. Healthcare-associated malaria is preventable through strict adherence to infection prevention and control procedures. Despite extensive investigations, the procedure leading to infection often remained unknown, highlighting the complexity of investigations. Guidance and protocols for conducting investigations may improve the success rate of such inquiries.</p>","PeriodicalId":12161,"journal":{"name":"Eurosurveillance","volume":"30 11","pages":""},"PeriodicalIF":9.9,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11927069/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143669533","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
