Johnson says following protocol, the roughly 45 students and track team coaches on the bus were taken to the hospital to be evaluated.

“All of our kids are fine. They’re back at the school this morning. Some of the book bags that they had on the bus were contaminated, and were kept by the hospital to be decontaminated,” Johnson said.

Johnson says those bags are expected to be returned to students, and accommodations made for any missed homework.
