Full Definition
Pertussis, commonly known as whooping cough, is a highly contagious respiratory tract infection caused by the bacterium Bordetella pertussis. The disease is characterized by three stages: catarrhal (cold-like symptoms), paroxysmal (severe coughing spells with the characteristic 'whoop'), and convalescent (gradual recovery). In infants and young children, pertussis can be particularly severe, leading to complications such as pneumonia, seizures, encephalopathy, and death. The condition is preventable through vaccination, but immunity wanes over time, making booster shots necessary.
