In response to 31 elementary students developing skin irritation at school on Wednesday, a group of parents are keeping their children home until further notice.
About 20 parents gathered at Daniel Cameron Elementary School Thursday morning and called the incident "traumatic." Until CPS cleans the school, they said, they're keeping their kids out of school.
"We were told that it was a chemical reaction to something. They really don't know what it is," said Mary Cirado, the mother of a 12-year-old student who experienced the irritation.
The school held a pep rally in the auditorium that involved spraying whipped cream, but officials said Wednesday the cream wasn't the cause of the reaction.
Classes resumed after the children were transported.
Cirado said her daughter, who had itching and burning on her arm and leg, was terrified.
"We have to do what we have to do," she said of keeping her daughter out of class.
In a statement released Thursday, Chicago Public School representatives said the school took proper precautions to protect students' safety.
Janitors "immediately sanitized the affected areas and proceeded to sanitize and clean the entire school," they said.
