Authorities are warning Territorians that monsoons are boosting the risks of people getting infected with a deadly tropical disease from bacteria found in soil.

Getting stuck in the mud has never been so dangerous in the Top End, as monsoons boost the risk of a deadly bacteria found in soil.

There's been 17 cases of melioidosis in the Northern Territory since October, and one person has already died.

That's higher than usual, and authorities are warning that contact with mud, puddles and wind-blown soil during heavy rain increases the chance of exposure to the tropical disease.

"The bacteria can invade the body through cuts and sores but it can also be breathed in if it's stirred up by the wind," Centre for Disease Control director Dr Vicki Krause said.

The highly infectious illness can lead to severe pneumonia and blood poisoning and has a mortality rate of 15 per cent, Dr Krause said.

"We usually see symptoms of fever, coughing and breathing difficulties but the symptoms of melioidosis can vary greatly," she said.

People usually get sick one to 21 days after coming into contact with the germs.

The onset of symptoms can be slow and may include signs like weight loss or sores that don't heal.

The soil-borne disease lies dormant deep in the ground for most of the year, but comes to the surface during the wet season.

Those at risk of catching melioidosis include gardeners who come into close contact with soil and people with compromised immune systems.

People at risk should stay indoors in windy and rainy conditions, Dr Krause said.

That includes those suffering from chronic alcoholism, diabetes, cancer or who are taking steroids.

"Labourers and other people who work with soil should always wear protective clothing, as healthy people can get the disease," Dr Krause said.

HOW TO AVOID MELIOIDOSIS:

* Stay indoors during heavy wind or rain
* Wear waterproof footwear and gloves around mud and areas of pooled water
* Wear masks when using high pressure hoses outside
* Avoid binge drinking.
