The impact of temperature on Ross River virus and Barmah Forest virus infection in Australia: A scoping review

Le résumé fourni par la source

OBJECTIVES: To summarise existing evidence on the impact of temperature on Ross River virus (RRV) and Barmah Forest virus (BFV) notifications across different geographical regions in Australia and to identify knowledge gaps. METHODS: A comprehensive search was conducted across three databases (PubMed, Embase and Scopus) from inception until March 2025. Studies quantitatively assessing the impact of temperature on RRV/ BFV infections were included. Identified studies were screened for eligibility, followed by data extraction and descriptive analysis. RESULTS: From 406 studies identified, 30 studies were eligible for inclusion. Overall, studies reported a positive association between high temperatures and an increased risk of RRV and BFV notifications in Australia. Geographical variations were observed with maximum temperature being associated with higher notifications of RRV infections in coastal Australia, whileminimum temperature increased the risk of RRV infections in inland regions, and for BFV infections across both regions. CONCLUSIONS: Studies reported an overall positive association between temperature and RRV/BFV notifications, with spatial variations observed in different regions of Australia. IMPLICATIONS FOR PUBLIC HEALTH: Given that most studies were carried out in coastal regions, there is a need to undertake further exploration in inland regions in Australia, at a smaller spatial scale to implement tailored prevention strategies.
