Whyalla Town Primary School students have been affected by a gastro outbreak while at an Adelaide Hills School Camp yesterday evening.
Between 15-20 students were affected, with two girls and one boy taken to the Women's and Children's hospital by emergency services.
Close to 60 Year 6 and 7 students from Whyalla Town Primary were attending the four-day camp.
Albury Park principal David Doherty said two of the children were hospitalised because they were not able to keep down anti-vomiting medication and needed fluids, while the other was an asthmatic.
“I would have to praise the work done by the teachers, under pressure they did a tremendous job at managing the incident,” Mr Doherty said.
Mr Doherty said a bus driver on the camp had also become ill, which could be linked to a possible cause.
“I would be hesistant to say, but it's possible there was something on that bus which could have contributed,” he said.
Students have now returned home, and those in hospital have been discharged.
Arbury Park Outdoor School is an outdoor education facility run by the Education Department with 90 dormitory beds.
