Parents of Clinton Elementary School in Columbus received a warning about Pertussis, or Whooping Cough, cases at the school.
A spokesperson with Columbus City Schools could not confirm how many cases the school has reported.
The letter stated that cases involve a "small number of students in the fourth and fifth grade."
Pertussis is a bacterial disease that is highly contagious.
According to the Ohio Department of Health, the illness usually starts with cold-like symptoms and maybe a mild cough. Pertussis is often not suspected or diagnosed until a persistent cough with spasms sets in after one or two weeks.
