Infección por Bordetella pertussis: Una causa emergente de tos prolongada en adolescentes y adultos

Abstract

Whooping cough is increasingly recognized as a cause of prolonged cough illness in adolescents and adults. Systematic vaccination has changed its epidemiology, with the majority of cases now primarily affecting adolescents and adults. A 45-year-old female, active smoker, nurse, who works in a dialysis service, presented with a 6-week history of bothersome cough and malaise. Thorax x-ray was normal and direct immunofuorescence of nasopharyngeal swab was positive for Bordetella pertussis. This case illustrates pertussis infection in adulthood. We review the main causes of chronic cough in adults: asthma, chronic rhinosinusitis and gastroesophageal refux; the clinical features, prevalence, diagnostic tools, and management of adult patients with B. pertussis infection to increase awareness of this highly contagious disease.
