Health update: Mosquito-borne viruses surge in Queensland
Queensland has seen a significant rise in mosquito-borne virus cases, with numbers more than tripling due to ongoing hot and wet weather. These weather conditions have created an ideal environment for mosquito breeding, leading to an increased number of mosquitoes and more opportunity for mosquitoes to transmit viruses.
Warmer temperatures also accelerate virus replication, meaning mosquitoes become infective more quickly.
Highest case numbers in Queensland in 4 Years
2024 saw the highest number of mosquito-borne virus cases in Queensland in 4 years, according to Queensland Health.
Cases of Ross River virus and the potentially deadly dengue fever more than tripled.
Health professionals are reminded to urge your patients to take precautions to avoid getting bitten.
Japanese encephalitis virus (JEV) vaccination
Japanese encephalitis virus (JEV) is a flavivirus related to dengue, yellow fever, and West Nile virus. While not all mosquitoes carry JEV, those that do can pose a serious health threat.
The Communicable Disease Network Australia has prioritised JEV vaccination for individuals at risk of exposure. Healthcare providers should ensure eligible patients are aware of their vaccination options.
Queensland Health recorded 3,225 cases, including 1 of Japanese encephalitis virus (JEV) – the first since 2022 – in the Wide Bay region.
Outside of Brisbane the Sunshine Coast recorded the most cases of mosquito-borne viruses with 495 and the Gold Coast and Darling Downs more than doubled the numbers on previous years with more than 200 cases each.
