At least 33 children, three adults fall ill at Lake Placid summer camp in Florida

At least 33 kids at a summer camp in Florida fell ill and are being examined, according to WFLA.com.

Officials in Highlands County say 33 kids and three adults from the Clover Leaf 4-H camp in Lake Placid began feeling nauseous — most began vomiting and suffering headaches.

The cause of the disturbance is still unknown.

The victims were rushed to local hospitals, according to Highlands County Public Safety Director Marc Bashoor.

Bashoor told CBS News Radio that one person passed out, prompting a 911 call. Miraculously, none of the cases appear to be serious.

Some children have been picked up, but about 50 of the 115 kids remains at the camp.

A call to Clover Leaf 4-H camp was not returned.
