Etymology

Origin of pertussis

1790–1800; < New Latin, equivalent to Latin per- per- + tussis a cough

Explanation

Pertussis is an illness that causes severe coughing, which can last for weeks or even months. Luckily, there is a vaccine for babies that protects them from getting pertussis. Pertussis is more commonly known as whooping cough for the distinctive, gasping "whoop" sound made during a coughing fit. Pertussis is highly contagious and especially dangerous for very young children and babies, who can stop breathing. The vaccine is very effective at preventing pertussis, although booster shots need to be given over time. Pertussis comes from per-, "thoroughly, and tussis, "cough."
