Abstract
Mosquito-borne viruses (MBVs) remain a significant public health concern in Northern Queensland, Australia, with dengue virus (DENV), Ross River virus (RRV), and Barmah Forest virus (BFV) representing the most common pathogens. Wolbachia-based biological control programs have made notable contributions to reducing dengue transmission by suppressing Aedes aegypti vector competence. Recent surveillance data indicates increased MBV activity, with national case numbers nearly doubling between 2023 and 2024 and early 2025 data suggesting sustained transmission during seasonal peak. Traditional surveillance approaches, while highly valuable for disease monitoring, have limitations in detecting novel or divergent viral strains in real time. Over the past decades, more than 919 unclassified flaviviruses have been reported nationwide, including 117 in Queensland. The advent of metagenomic and metatranscriptomic approaches now enable enhanced, field-based detection of both known and emerging arboviruses. Strengthening mosquito control programs through continued Wolbachia releases, alongside integrated genomic surveillance, predictive modelling, and community engagement will enhance early detection, guide targeted interventions, and reduce the MBV burden in Northern Queensland. This integrated framework provides a strategic pathway to sustains and expand vector control effectiveness while safeguarding public health in high-risk regions.
