McCANDLESS TOWNSHIP, Pa. - A third North Allegheny School District student has been diagnosed with pertussis, more commonly known as whooping cough.
Whooping cough is a disease which is spread through the air when a contagious person sneezes or coughs.
North Allegheny posted the following information from the Allegheny County Health Department on its website:
“Older children or adults can also carry the pertussis bacteria home. Children who are too young to be vaccinated or who have not completed the vaccination series and adults whose immunity from vaccination has begun to wane are most susceptible to infection.”
