The child’s parents emailed the letter to the Register on Wednesday, aiming to inform the entire school community of the matter.
The girl, 7, who is in first grade, was vaccinated against the respiratory disease but still contracted it, her parents said. They’re awaiting test results, which would officially confirm the diagnosis. She has been removed from classes but attended earlier this week and rode a school bus when she may have been contagious, her parents said.
On Friday, the Erie County Health Department will notify the parents of their child’s official diagnosis, they said.
Whooping cough, formally referred to as pertussis, is a highly contagious bacterial infection that causes violent, uncontrollable coughing, making it difficult to breathe, according to the letter, which the Erie County Health Department authored. Most children are immunized from the disease, but the vaccination is only 85 percent effective.
