Queensland’s chief health officer, Dr John Gerrard, has issued a warning regarding an escalating risk of Ross River virus infections this year. Recent testing of over 700 mosquito traps across the state has detected significantly high levels of the virus, surpassing those recorded during the 2019-20 outbreak. Currently, there have been 31 positive traps identified, which is already more than the total from last summer’s significant outbreak.
Gerrard expressed concern over the early indications of heightened virus activity across a wide area, suggesting that Queensland may be heading for another year of high infections. Historically, Ross River virus cases tend to increase with the onset of rain and warmer temperatures, typically peaking in February and March. Since there was a notable rise in cases every three to four years, health officials are monitoring the situation closely.
The Ross River virus, primarily transmitted through mosquito bites, can cause joint pain, fatigue, fever, rashes, and swollen joints, with symptoms potentially lingering for months. There is currently no vaccine or specific antiviral treatment, making prevention crucial. Residents are advised to take measures to avoid mosquito bites, particularly considering the current high mosquito population due to favourable weather conditions.
