Far North Queenslanders are being warned by public health officials to take precautions particularly with swimming pools as stomach bug cases spike in the region.

Since the start of 2024, 25 cryptosporidiosis cases have been reported in the Cairns region.

Cryptosporidiosis is a gastrointestinal disease caused by the microscopic parasite Cryptosporidium and is a common cause of acute diarrhoea in young children.

A rise in cryptosporidiosis cases has been reported nationwide across Queensland, New South Wales and Victoria in recent weeks, with many of the cases being diagnosed in children aged nine years and under.

Tropical Public Health Services Cairns director Dr Richard Gair said Cryptosporidium was usually acquired through the ingestion of contaminated water or food, or through contact with infected individuals or animals.

“Drinking or accidentally swallowing water contaminated with Cryptosporidium parasites is a common mode of transmission. This can occur in places such as swimming pools, water parks, and other recreational water facilities where water may be contaminated with faecal matter,” Dr Gair said.

“The most common symptom of cryptosporidiosis is diarrhoea, especially in young children. Other symptoms include nausea, vomiting, fever, headache, and loss of appetite.

He said people should avoid swimming in pools, water parks or other recreational water facilities for at least 14 days after diarrhoea has ceased.

“Swimming pool operators also need to make sure that their swimming pools are properly maintained,” he said.

“This includes ensuring water quality is well maintained alongside good filtration, and disinfection processes.”

People experiencing severe illness, difficulty maintaining adequate fluid intake or long-lasting diarrhoea should seek medical advice.
