Officials in the Canfield Local School District are trying to control the spread of illness.

A post on the Canfield Schools Facebook page states that there has been “an abundance” of illness at the high school.

The district says it is working with the health department to stop the transmission of the illness, which it does not name.

The post asks parents to keep students at home if they have active symptoms including coughing, congestion, fever, sore throat, and body aches.

The district also advises parents to contact their school nurse if they have any questions.

The CDC reports that influenza activity in Ohio is “very high” with the highest rates in the zero to 19 age group.

For the week ending November 26, the number of flu-related hospitalizations in Mahoning County was 21; 11 in Trumbull County, and seven in Columbiana County.
