QUEENSLANDERS are being urged to take precautions against mosquito bites after the first detection of Japanese Encephalitis Virus (JEV) in Brisbane.
Queensland Health confirmed the virus was found in mosquito surveillance samples in Hemmant and warned the risk of human exposure may increase following recent flooding from Ex-Tropical Cyclone Alfred.
Chief Health Officer Dr Heidi Carroll said this detection suggests JEV is spreading in mosquito populations across Queensland.
“This is the first detection for Brisbane, and we have already identified JEV activity in the Goondiwindi and North Burnett regions,” Dr Carroll said.
“It’s critical that Queenslanders remain extra vigilant against mosquito bites, as JEV can cause severe neurological illness and, in some cases, be fatal.”
She advised residents to use insect repellents containing DEET, picaridin or oil of lemon eucalyptus, wear loose-fitting, light-coloured clothing, and eliminate standing water around their homes to reduce mosquito breeding.
JEV spreads when mosquitoes bite infected pigs or wading birds before biting humans. While most infected people experience mild or no symptoms, severe cases can lead to fever, headaches, vomiting and, in rare instances, death.
A JEV vaccine is available for people at high risk, including piggery workers and those living near piggeries. More than 18,000 Queenslanders have been vaccinated since 2022, with free vaccines available at selected GPs and pharmacies.
There are no vaccines for Ross River or dengue viruses, making prevention essential. Queenslanders should take steps to avoid mosquito bites, especially during dusk and dawn when some species are most active.
