A rare tropical disease which can spread just by breathing it in has left at least 31 people dead in Queensland.

Some 221 cases of melioidosis have been reported so far this year,which is up by 163 compared to this time last year.

The family of Evan Brown who was killed after contracting the disease last year has urged residents to be vigilant.

He was taken to hospital with multiple organ failure and septicaemia just days after his 40th birthday.

His wife Sarah said: ‘Knowing what we went through as a family and having so many other people who were impacted by our news,it makes me scared for the general populous because it’s clearly in our area,the flooding is causing it to be present.’

The soil borne disease has spread due to heavy rain and flooding bringing the bacteria to the surface,with tropical cyclone Alfred exacerbating the spread.

It then enters the body through cuts,drinking contaminated water of even just breathing it in after heavy rain.

Queensland Health said: ‘Cases are most commonly reported in residents of the Torres and Cape,North West,Cairns and Hinterland and Townsville regions.’

Cases increased by 400% in Cairns and 600% in Townsville this year.

How is melioidosis treated?

Melioidosis first presents itself as a common infection,with experts describing the bacteria as a ‘great imitator’.

Queensland Government said: ‘Melioidosis is treated with strong antibiotics for at least three months.

‘People who are very sick will usually need to go to hospital and might need treatment in intensive care.

‘It can be fatal if not treated with the right antibiotics.’

People living in high-risk areas have bene encouraged to wear correct footwear when outside.

Who is most at risk of catching melioidosis?

It is rare healthy adults and children catch and become unwell from the disease.

But people with long term illnesses including cancer,diabetes,lung and kidney diseases are at risk.

Heavy alcohol drinkers are also more susceptible to catching the bacteria.

Pets can also contract the disease from other animals.
