biostudies-literatureUnknown13(7)Viennet EArboviruses pose a significant global public health threat, with Ross River virus (RRV), Barmah Forest virus (BFV), and dengue virus (DENV) being among the most common and clinically significant in Australia. Some arboviruses, including those prevalent in Australia, have been reported to cause transfusion-transmitted infections. This study examined the spatiotemporal variation of these arboviruses and their potential impact on blood donation numbers across Australia. Using data from the Australian Department of Health on eight arboviruses from 2002 to 2017, we retrospectively assessed the distribution and clustering of incidence rates in space and time using Geographic Information System mapping and space-time scan statistics. Regression models were used to investigate how weather variableBiology524https://www.ebi.ac.uk/biostudies/studies/S-EPMC11273437biostudies-literatureArbovirus Transmission in Australia from 2002 to 2017.PMC11273437Frentiu FDViennet ETorres Vasconcelos FFlower RLPFaddy HMMcKenna EfalseArbovirus Transmission in Australia from 2002 to 2017.Arboviruses pose a significant global public health threat, with Ross River virus (RRV), Barmah Forest virus (BFV), and dengue virus (DENV) being among the most common and clinically significant in Australia.
