The NT Centre for Disease Control has issued urgent alerts for residents and visitors to remain vigilant against melioidosis, following an increase in cases of the soil-borne disease amid recent wet weather in the Top End.

The CDC reported a notable rise in melioidosis cases in recent weeks, with 25 recent cases recorded as of Friday and new cases emerging approximately every one to two days since New Year’s Eve.

The cases span all age groups, though the majority are among individuals aged 45 or older, with both males and females represented nearly equally, the health department said.

The NT reported 65 cases along with five fatalities last wet season.

Melioidosis bacteria reside deep in soil, especially during the wet season. Heavy rainfall can bring these bacteria to the surface, while wind can aerosolise them, making them inhalable through dust and droplets, the government said.

Individuals who are immunocompromised, including those with diabetes, chronic health conditions, or on immunosuppressive treatments, have a higher risk of contracting melioidosis.

Melioidosis can lead to severe pneumonia and sepsis, with a 10 per cent fatality rate. Three cases this wet season required intensive care.

Symptoms of melioidosis may include prolonged fever, cough, and difficulty breathing, but they can also affect various parts of the body, leading to abscess formation. The bacteria responsible for melioidosis can cause difficult-to-heal skin wounds. Timely initiation of treatment for melioidosis is crucial, the government said.

As a precaution, Territorians are advised to wear covered, waterproof footwear outdoors and gloves when gardening or working in soil. Wash and cover any sores with waterproof dressings, and consider wearing a mask when using high-pressure hoses near soil. Stay indoors during heavy wind and rain, and seek medical attention if experiencing symptoms.

Those experiencing symptoms of melioidosis should see their local GP, clinic, or hospital for advice.
