What is pertussis?

  • Pertussis, also known as whooping cough, is a highly contagious respiratory infection.
  • Pertussis is known to cause uncontrollable, violent coughing which often makes it hard for the patient to breathe.
    After a prolonged bout of cough, children with Pertussis often need to take a deep breath which results in a "whoop” sound.
  • Pertussis in young infants can be severe and at times, fatal.

What are the symptoms of pertussis?


Symptoms vary according to age groups.

  • Classically, children present with fits of rapid and hard coughs followed by a gasping breath which makes a “whoop” sound. Children may vomit and feel exhausted after such fits of cough.
  • Young infants may not have such coughs or whoops. They may gasp for breath and turn blue. They could have trouble feeding or sleeping due to the coughing fits.
  • Adolescents and adults usually have a prolonged (>3 weeks) coughing illness without the whoop.
