Rising Whooping Cough (Pertussis) Cases in Schools

Whooping cough (pertussis) is making a noticeable comeback in schools across the U.S., including here in Massachusetts. With students spending long days together in classrooms, cafeterias, and on school buses, this highly contagious respiratory infection can spread quickly—often before symptoms are recognized. Recent CDC data shows cases remain higher than usual in 2025, making it especially important for families to understand how pertussis spreads, what symptoms to watch for, and when to seek medical care. Staying informed can help protect your child and your community during this rise in cases.
