The word pertussis means “violent cough,” which aptly describes the most consistent and prominent feature of the illness. The inspiratory sound made at the end of an episode of paroxysmal coughing gives rise to the common name for the illness, “whooping cough.” However, this feature is variable: it is uncommon among infants ≤6 months of age and is frequently absent in older children and adults. The Chinese name for pertussis is “the 100-day cough,” which accurately describes the clinical course of the illness. The identification of B. pertussis was first reported by Bordet and Gengou in 1906, and vaccines were produced over the following two decades.
