Abstract:
Once a prevalent disease, acute epiglottitis in children has become a rare entity. The introduction of the Haemophilus influenzae type b vaccine has had a dramatic impact on the number of invasive infections caused by this organism. However, physicians must be aware that epiglottitis may result from vaccine failures or from infection with other pathogenic organisms. Vaccinated children with epiglottitis present in a similar fashion to those who are not vaccinated. We present a rare case of acute epiglottitis in a fully vaccinated child due to nontypeable H. influenzae and discuss the clinical presentation and management.
