KLAMATH FALLS, Ore. -- Health officials in Klamath County have identified two confirmed cases of whooping cough in children.

Officials say one infected child is a student at Shasta Elementary school, the other attends Henley Middle School.

Efforts are being made at both schools to identify close contacts of the two infected children in order to prevent the spread of the disease.

Officials say anyone who has not been immunized is at risk.
