Queensland Health is urging people in flood-affected areas to be mindful of the risk of disease from floodwaters.
Residents across southern Queensland are cleaning up after the recent wild weather, while some are still waiting for high river levels to subside.
The Darling Downs Public Health Unit's environmental health manager, Virgil Kelk, says simple precautions must be taken.
"Like wearing good stout boots, put on some gloves, if necessary just a little face mask and every time that we stop to have something to eat or have a cigarette make sure that we give our hands a wash," he said.
"Hand washing is absolutely critical and it's our primary protection against a whole range of things that can make us quite unwell."
