The students were inside the school's gym for a Thanksgiving prayer assembly, officials said. Officials said the area of concern was isolated and the school was placed on lockdown but there was no further threat to students.
Officials say they responded within five minutes and began checking almost everything that could be to blame, including cleaning supplies, AC units, gas leaks, even going as far as to do hazmat sweeps that checked for more than 5,000 chemical compounds, all of which came back negative.
All patients have been medically cleared and released from the hospital, fire officials said Monday night.
There is no further information on what might have caused symptoms.
