International data indicate the importance of iGBS infections among non-pregnant adults.<h4>Aims</h4>To describe the burden of iGBS infections in Western Australia (WA) between 2000 and 2018 in terms of incidence, length of hospitalisation and all-cause 30- and 90-day mortality.<h4>Methods</h4>This was a retrospective, population-based study using linked data from the state government-owned pathology provider, hospitalisations and death registrations. Children and adults with isolation of GBS in a normally sterile site or a hospital-based diagnosis of iGBS infection were included.<h4>Results</h4>There were 2861 cases; just over a quarter (Internal medicine journal453-460https://www.ebi.ac.uk/biostudies/studies/S-EPMC11900862biostudies-literatureInvasive group B streptococcal infections in Western Australia, 2000-2018.PMC11900862Wright CMMoorin RCarapetis JDyer JManning LfalseInvasive group B streptococcal infections in Western Australia, 2000-2018.<h4>Background</h4>Neonatal and puerperal sepsis are major manifestations of invasive group B streptococcal (Streptococcus agalactiae; iGBS) infections.
