pertussis
Pronunciation: per-TUH-sis
Highly contagious bacterial respiratory infection caused by Bordetella pertussis, characterized by paroxysmal coughing fits and inspiratory whoop in children.
Full Definition
A highly contagious respiratory infection caused by Bordetella pertussis, also known as whooping cough. The disease has three stages: catarrhal (cold-like symptoms), paroxysmal (characteristic paroxysms of coughing followed by inspiratory whoop), and convalescent (gradual recovery). Infants under 6 months are at highest risk for severe disease and complications including apnea, pneumonia, and death. Diagnosis is confirmed by PCR or culture from nasopharyngeal specimens. Treatment with macrolide antibiotics is most effective when started in the catarrhal stage. Editorial attention should focus on proper bacterial nomenclature and accurate staging terminology.
Usage
Usage note: Use 'pertussis' in formal medical documentation; 'whooping cough' is acceptable for patient communication.
