The first autochthonous dengue case was recorded in 2010, and by 2021 the disease was detected in 78% of the neighbourhoods. DENV-1 was the dominant serotype and most cases occurred among people aged 20–59. Clusters of vectors and dengue cases were more frequent during summer and autumn, but a few were also identified during winter. High-risk clusters for vectors were more frequent in the Partenon and Northwest regions and for dengue in the East, Centre, Partenon and South.</div></div><div><h3>Interpretation</h3><div><em>Ae. aegypti</em> successfully established and spread within a temperate city in Brazil. The presence of vectors, a susceptible population and socio-environmental characteristics conducive to mosquito proliferation resulted in autochthonous transmission of dengue fever after the continuous introduction of imported cases. The climatic barrier to dengue transmission in the south of Brazil has shifted southward, coinciding with the colonisation of <em>Ae. aegypti</em> and the emergence of dengue in recent years in Porto Alegre.</div></div><div><h3>Funding</h3><div><span>Generalitat de Catalunya</span>, <span>European Commission</span>, and <span>Conselho Nacional de Desenvolvimento Científico e Tecnológico</span> (CNPq).</div></div>","PeriodicalId":29783,"journal":{"name":"Lancet Regional Health-Americas","volume":"48 ","pages":"Article 101153"},"PeriodicalIF":7.0,"publicationDate":"2025-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144365894","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

An individualised haemodynamic resuscitation strategy is emphasised to avoid volume overload and not delay the use of norepinephrine in persistent hypotension. Additionally, we recommend addressing haematological and respiratory complications, including platelet transfusion restrictions and strict intra-abdominal pressure monitoring.
