Great Valley School District notified parents Friday morning of a fourth case of whooping cough in the district. A student was diagnosed with the highly contagious disease, which had previously been found in at .
The letter to parents, signed by superintendent Alan Lonoconus, explained that students at the elementary school could have been exposed to the disease:
We learned today that one K.D. Markley student has a confirmed case of pertussis, which is also known as whooping cough. That student is currently under a doctor’s care and will not return to school until the doctor provides a note that the student is no longer contagious. However, your child may have been exposed between February 1, 2012, and February 3, 2012.
The average incubation period for Pertussis is 9–10 days, but ranges from 6-20 days. Pertussis is a highly contagious disease that is spread through the air when an infected person sneezes or coughs. Pertussis begins with cold symptoms and a cough that becomes much worse over 1-2 weeks. Symptoms usually include a long series of coughs (“coughing fits”) followed by a whooping noise. However, older children, adults and very young infants may not develop the whoop. There is generally no fever. People with Pertussis may have a series of coughs followed by vomiting, turning blue, or difficulty catching their breath. The cough is often worse at night and cough medicines usually do not help alleviate the cough. The disease can be very severe and, although deaths are rare, they do occur, especially in infants less than one year of age. For your information, the Pennsylvania Department of Health’s Fact Sheet is provided with this letter.
