A potentially dangerous mosquito-borne virus, Japanese encephalitis (JE), has been identified in Brisbane for the first time, prompting health officials to issue warnings. The discovery coincides with concerns over increased infection risks due to wet weather influenced by ex-tropical Cyclone Alfred, which could lead to a surge in mosquito populations.
Professor Paul Griffin, an expert in infectious diseases, highlighted that JE is rarely encountered in South-East Queensland, and its appearance in local mosquitoes is alarming. Queensland Health has cautioned that residents throughout the region should remain vigilant.
Following a recent rise in wet weather conditions, authorities fear that the virus may spread further as mosquito numbers grow. Griffin acknowledged the seriousness of the situation, urging people to stay informed and take precautions.
This latest detection comes after Queensland recorded its first locally acquired JE case since 2022. Meanwhile, New South Wales has reported five cases in recent months, including a man in his 20s who travelled to the northern part of the state. Tragically, two fatalities associated with the virus have occurred there this year.
Symptoms of Japanese encephalitis can include fever, headaches, nausea, neck stiffness, and disorientation, although many cases are mild or asymptomatic. To protect against infection, health authorities recommend wearing long sleeves and pants, using mosquito repellent, and avoiding outdoor activities at dawn and dusk. Vaccines are available for free across the country for individuals at higher risk due to their occupation or living conditions.
