Cattell Elementary School has still now answers to causes of illness

Cattell Elementary School still has no answers to a mysterious illness that knocked down 22 kids last Thursday.

At 1:30 p.m. a group of kids began to show symptoms like lightheadedness, nausea and even vomiting. They were immediately delivered to Methodist Medical Center in Des Moines . All have been treated and released later.

The health department conducts an investigation including interviews and air sample tests. The department suspects that children were exposed to carbon monoxide.
