    Pertussis, also known as whooping cough, is a highly contagious respiratory disease. It is caused by the bacterium Bordetella pertussis.

    Pertussis is known for uncontrollable, violent coughing that often makes it hard to breathe. After fits of many coughs, someone with pertussis often needs to take deep breaths, which result in a “whooping” sound. Pertussis most commonly affects infants and young children and can be fatal, especially in babies less than 1 year of age.

    The best way to protect against pertussis is immunization.
