Health authorities in Queensland have confirmed that the death toll from melioidosis, a rare tropical disease, has risen to 12 following widespread flooding and heavy rainfall in the state’s northeast. The number of fatalities has more than doubled since February 21, when only five deaths had been reported.
According to local health officials, the 12 deaths occurred across two major cities: nine in Cairns, the region’s largest city, and three in Townsville, located approximately 300 kilometers to the south. The surge in cases follows unprecedented rainfall that affected Queensland’s tropical northern coast earlier this month, with many areas experiencing record-breaking rainfall over a short period.
Melioidosis, caused by a bacteria commonly found in soil and water in Southeast Asia and northern Australia, has become airborne after the heavy rainfall, exacerbating the spread of the disease. The bacteria typically infects individuals through contact with contaminated soil or water, and the risk is heightened during wet conditions.
As of early 2025, there have been 53 confirmed cases in Cairns and 34 in Townsville. Jacqueline Murdoch, Director of Tropical Public Health Services, described this as a “record-breaking year” for melioidosis in the region, with cases and deaths reaching alarming levels. “It’s a very severe disease with a high fatality rate,” Murdoch said, emphasizing the significant toll on older residents.
Health authorities have urged the public to exercise caution during heavy rainfall, advising people to avoid contact with soil and wear masks when using high-pressure hoses. Anyone experiencing respiratory symptoms, such as a cough or difficulty breathing, is encouraged to seek medical attention immediately.
Melioidosis has become a growing concern as Queensland continues to grapple with the aftermath of extreme weather events, underscoring the challenges posed by climate-related health risks.
