A Mathayom 5 student, who asked not to be named, said she had developed stomach pains and felt bloated after eating her dinner on Monday and had been suffering from diarrhoea throughout the night.
Many of her friends were also suffering with the same symptoms, she said.
The camp had been attended by high-schoolers aged 16-18 from 96 schools around the country.
