MAYFIELD - A case of pertussis, or whooping cough, was confirmed Friday at Mayfield Junior-Senior High School, and district officials began notifying parents.
Children who have been around someone with pertussis can become sick with the disease. Mayfield school officials warned that even children who have received their pertussis vaccines - DPT or DTaP - can still become ill.
Pertussis is highly contagious and is spread through the air by coughing. The disease begins with cold symptoms, a slight fever and coughing, but can also include vomiting, turning blue and difficulty breathing.
The state Department of Health recommends that a child who has developed the symptoms should be taken to the doctor immediately, and parents should tell the doctor if pertussis has been diagnosed in their child's school.
It also notes infants younger than one year old - especially those younger than six months - are most likely to have severe symptoms if they contract the disease. Infants should be kept away from people with a cough and should be brought to a doctor immediately if they develop a coughing illness.
