What is pertussis?

ANSWER

Pertussis, or whooping cough, is an extremely contagious respiratory infection that can lead to severe breathing problems, especially in infants. Pertussis first appears like an ordinary cold, but then causes intense, uncontrollable coughing spells. You'll hear a "whoop" noise when you try to take a breath after coughing.
