Townsville Records Three Deaths from Rare Tropical Disease; Dengue Fever Cases Also Probed
Introduction: A Surge in Health Risks Following Heavy Flooding
Health authorities in North Queensland are sounding alarms following the death of three elderly people from melioidosis, a rare tropical disease linked to heavy rains and flooding. Two of the deaths occurred in the Townsville area, while one was recorded in Ingham, contributing to a rise in cases across the region. As the region grapples with the aftermath of significant flooding, experts are warning that more health risks could emerge. Along with the melioidosis deaths, there are also concerns about a potential outbreak of dengue fever and worsening respiratory issues due to mould infestations in homes.
Melioidosis Deaths: A Growing Threat Post-Floods
Melioidosis, caused by soil-borne bacteria, is spreading across the region with more than 20 cases recorded in Townsville this month alone. The recent uptick in cases has raised concerns among health experts, particularly given that the disease can be fatal, especially for vulnerable populations such as the elderly and those with pre-existing health conditions.
On Thursday, two elderly individuals in Townsville succumbed to the disease, and a third death occurred in the past week. These fatalities are part of a broader spike in melioidosis cases, with the Cairns region having already recorded four deaths from the disease this year, marking an unprecedented rise in infections.

Townsville Public Health Unit Director Steven Donohue acknowledged that the current surge in melioidosis cases was higher than typical seasonal levels, attributing the spike to the heavy rains and flooding. “We’re hoping that these numbers will begin to decline after the heavy rains are cleaned up,” Donohue said, though he expressed concern over the possibility of another cyclone exacerbating the situation.
Melioidosis: Risks and Precautions
The rare tropical disease typically emerges after heavy rainfall and flooding, as the bacteria in the soil become more widespread. Donohue stressed that melioidosis posed a particular threat to older individuals or those with compromised immune systems. He recommended that vulnerable people avoid participating in flood clean-up efforts, as they are at greater risk of exposure to the disease. “If you’re older and sick, you should be making the sandwiches and leave the clean-up to younger people,” he advised.
For those involved in clean-up activities, Donohue emphasized the importance of wearing personal protective equipment, including boots, long pants, long sleeves, and masks when using high-pressure hoses to avoid exposure to contaminated soil and water.
Dengue Fever Concerns: A New Outbreak Investigation
In addition to melioidosis, health authorities are also investigating a cluster of three locally acquired dengue fever cases in Townsville. The cases, which include two individuals from the same household and a neighboring resident, have raised concerns about the potential for a larger outbreak. Dengue fever, which is transmitted by mosquitoes, had been relatively rare in the region since mosquitoes carrying dengue-resistant bacteria were released 15 years ago. However, Dr. Donohue confirmed that the recent cases technically constitute an outbreak, though he expressed confidence that it would not become a widespread community threat.
“The risk of this dengue outbreak spreading further is low, but we’re closely monitoring the situation,” Donohue said.
Melioidosis and Dengue Fever: A Double Health Threat
As melioidosis and dengue fever cases continue to rise in the wake of flooding, experts warn that the combination of these diseases could strain the already overwhelmed healthcare system. Both illnesses can be serious, with dengue fever causing symptoms such as fever, joint pain, and rashes, while melioidosis can lead to severe infections affecting the lungs, bloodstream, and other organs.
James Cook University microbiology professor Jeff Warner explained that the high number of melioidosis cases in the region could be linked to recent disruptions in the soil caused by roadworks in Cairns, which may have exposed more people to the bacteria. Warner also emphasized the importance of continued research to understand how melioidosis is spreading and how to better protect the population.
Flood-Related Mold Growth: An Additional Health Hazard
Another pressing concern emerging from the floods is the rapid spread of mould in flooded homes across North Queensland. Mould growth can exacerbate respiratory conditions such as asthma and cause allergies in sensitive individuals. Kate Miranda, Chief Executive of Asthma Australia, warned that the wet conditions were creating an environment conducive to mould infestations, which could cause serious health complications for people with weakened immune systems or respiratory issues.
For those affected by flooding, Miranda advised prompt action to remove mould and improve ventilation in affected homes. “Mould can be a significant threat to people with respiratory conditions, and the longer it is left untreated, the worse it becomes,” she said.
Looking Ahead: Health Authorities Urged to Stay Vigilant
With the combined threat of melioidosis, dengue fever, and mould-related health issues, health authorities in North Queensland are urging residents to take precautions during the ongoing clean-up efforts. Donohue highlighted that the impact of flooding on public health could extend beyond the immediate aftermath of the storms, with illnesses continuing to emerge in the coming weeks.
“The health risks we’re seeing now are just the tip of the iceberg. We’re likely to see more infections in the coming weeks,” he warned, urging the public to remain vigilant and follow health guidelines to minimize their exposure to the various dangers present in the flood-affected areas.
As floodwaters recede and the clean-up process continues, North Queensland’s residents are being reminded to take extra care in protecting themselves from the ongoing health threats. The collaboration of local health authorities, researchers, and residents will be essential in preventing further spread of these diseases and safeguarding public health in the aftermath of the floods.
Conclusion: Urgent Action Needed in Flood-Ravaged North Queensland
With the continuing flood recovery efforts, North Queensland faces an uphill battle against the health risks posed by melioidosis, dengue fever, and mould infestations. Health experts and local authorities are working tirelessly to address the surge in infections and to provide guidance to the public on how to protect themselves during the clean-up process. For now, the region’s focus remains on minimizing health risks and preventing further outbreaks in the coming weeks.
