The kids developed symptoms of acute gastroenteritis including diarrhea and stomach pain between three to 18 hours after lunch on campus, the CHP said.

Seven pupils have sought medical treatment but did not require hospitalisation, the CHP said, adding all affected students are in stable condition.
