This study aimed to determine the incidence and risk factors for developing Vibrio species bloodstream infections and compare differences between different species. The study found an incidence rate of 1.2 cases/1 million person-years for Vibrio infections in Australia, with the highest incidence occurring in the summer months and in the tropical north. Increasing age, male sex, and multiple comorbidities were identified as risk factors. Vibrio vulnificus was the most frequently isolated pathogen and associated with the most severe disease. The overall case fatality rate was 19%.
BackgroundVibrio species bloodstream infections have been associated with significant mortality and morbidity. Limited information is available regarding the epidemiology of bloodstream infections because of Vibrio species in the Australian context. AimsThe objective of this study was to define the incidence and risk factors for developing Vibrio species bloodstream infections and compare differences between different species. MethodsAll patients with Vibrio spp. isolated from positive blood cultures between 1 January 2000 and 31 December 2019 were identified by the state-wide Pathology Queensland laboratory. Demographics, clinical foci of infections and comorbid conditions were collected in addition to antimicrobial susceptibility results. ResultsAbout 100 cases were identified between 2000 and 2019 with an incidence of 1.2 cases/1 million person-years. Seasonal and geographical variation occurred with the highest incidence in the summer months and in the tropical north. Increasing age, male sex and multiple comorbidities were identified as risk factors. Vibrio vulnificus was isolated most frequently and associated with the most severe disease. Overall case fatality was 19%. ConclusionsThere is potential for increasing cases of Vibrio species infections globally with ageing populations and climate change. Ongoing clinical awareness is required to ensure optimal patient outcomes.
